Preface

This user's manual describes the installation, commissioning and maintenance of 17C-5S-A01 wide band consumer repeaters of LTE700(A+B+C) +CDMA/GSM850+ PCS/GSM1900+AWS five systems. Please do read user manual carefully before installing and maintaining the repeaters. The information in this manual is subject to change without prior notice. Opinions are welcomed about the manual improvement.

1. Safety Warnings

Users must follow the below principles  Repeater should follow system requirement of communication equipment, assure good grounding and
lightning protection.  The power supply voltage of repeater should meet the standards of security requirement; any operation
shall be carried out only after cutting off power in advance. Only the professional is authorized for the operation.  Do not dismantle machine, maintain or displace accessories by yourself, because in this way, the equipment may be damaged and you may even get an electric shock.  Do not open the repeater, touch the module of repeater, or open the cover of module to touch the electronic component. The components will be damaged due to electrostatic.  Please keep away from heating-equipment, because the repeater will dissipate heat during working. And do not cover booster with anything that influences heat-dissipation.

2. Introduction
Our 17C-5S-A01 full band repeater is the perfect solution for providing a wireless improvement in the cellular reception of a home, office, restaurant, VIP Room, apartment, building or shopping mall, in the quickest time possibly. One repeater covers 50 to 2000 square meters.
In order to maintain safe and specific output signal levels, this repeater has built-in signal oscillation detection circuit to adjust the gain automatically so as to avoid interference to the cellular network.
Below diagram shows how simple and fast the repeater system is installed and works effectively: One Yagi antenna, as donor antenna, is installed at the top of the roof to pick up good mobile phone signals from outside, and send through 5D-FB cable to repeater to amplify the signals significantly, then the output signals are sent to the indoor omni antennas and finally transmitted into the covering area. Very clear phone call or high speed mobile data are immediately achieved within the area.

7.4. Installation of donor antenna
The repeater's main function is to improve weak RF signals of an area. A simple formula: Input power+ Gain= Output power. The signal strength from the outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the donor antenna location in order to get the best signals.

 Testing the signal strength received from donor antenna mounted in site by mobile phone:  Please select the top of building to install the donor antenna if total floors are less than 7 floors, and shall try your best to select places like balcony or platform lower than 7th floor for donor antenna if the buildings are over 7 floors, because the mobile signals are clean at less than 7th floor.  The mobile phone shall display full bar signals in location where the donor antenna is installed  The phone calls or data transmission shall be smooth and stable by 3 times testing in location where the donor antenna is to be installed  As shown from the above illustration, testing the signals from A to E, and select a best place that displays full bar signals to install the donor antenna.
 Selecting the installation direction of donor antenna.  The donor antenna shall point to the direction of the tower, and it would be much better to keep line of sight.  Please select the opposite directions for donor antenna and server antenna. If donor and server antennas have to be installed in the same direction, please install them only after the signal quality is tested and the self-oscillation is avoided. If the directional antenna is selected, the
- 13 -

main directional angle should point to the tower antenna.

SZZJ-A17F-5S User Manual

 If the performance is poor due to weak signals or poor phone call quality, please adjust the

direction of donor antenna or change its position in order to obtain the best calling effect.

 The wide band repeater supports all mobile operators or different mobile systems, so please

adjust the donor antenna direction to have balance between signals of different mobile operators

or various mobile systems.  Donor antenna installation ---Notes:

 Do not install the donor antenna during the rainy day with lightning.

 Please follow the instructions to install the donor antenna.

 It is a must that the waterproof shall be done to connectors of donor antenna and feeder lines.

 In order to avoid interference, please note that the donor antenna should be far away from the

following objects of metal, high-voltage line, and RF antenna and high-voltage transformer.

 Repeater is a two-way signal amplifier. So proper isolation between donor antenna and server

antenna is necessary in order to avoid self-oscillation. About the definition for self-oscillation,

take MIC and loudspeaker for example; if it is too close for each other, it could make big noise.

So the repeater can only run smoothly if alarm LED always remains GREEN color.

 The minimum distance between donor antenna and server antenna shall be more than 10

meters; again the direction of donor and server antennas shall be opposite.

As shown in the below illustration, the booster amplifies the downlink signal r from the tower and send to the indoor antenna hereafter. If the distance between outdoor antenna and indoor antenna is less than the required distance, the amplified signal R will go back from indoor antenna to outdoor antenna. So it will lead to self-oscillation and reduce the coverage area, also the bad calling quality could happen at the same time, and the worse is that the mobile network could be influenced badly and the operators will finally come to shut off the repeater system.

Fix the donor antenna after selecting the best position, and adjust slightly its height or angles in order to get the signals with suitable input power level and calling quality.  System Requirement of GSM or PCS
1) The total input power level shall be around -50dBm, lowest shall be more than ­80dBm 2) Test by mobile phone or data card by 3~5 times to make sure the calling quality is good at
95% of the time, and no handovers. 3) It is requested that the leading BCCH shall be 6dB higher than the second BCCH in order
to avoid call drops (for professional engineering reference only).  System Requirement of CDMA or AWS
- 16 -

SZZJ-A17F-5S User Manual
1) The input power level shall be around -55 ~ -60dBm (it is less than GSM or DCS because of breathing effect), the lowest shall be more than ­90dBm.
2) Test by mobile phone or data card by 3~5 times to make sure that Ec/Io is more than ­7dB, and no handovers.
3) Ec/Io of adjacent carrier shall be 8dB less than that of donor carrier to avoid soft handover. The active PN shall be only 1.
7.5. Cable layout and connector assembly
1) Keep the type, specifications, routing direction, location, and curvature radius of cables in compliance with the design requirement. Place cables in good order, bend them smoothly, and protect the outer skin against any damage.
2) Bind cables in good order when laying them on cable racks. When leading cables in or out of troughs, use a hole-opener to open cable troughs and then install PVC lock-nuts to protect them.
3) Keep horizontal cables straight and fasten them stably with a fixing clip every 1 to 1.5 meters, with a proper stress.
4) Bind and fasten vertical cables every two to three meters to avoid damaging cables or connectors owing to their own heavy weight. Take back the cables and re-lay them when you have difficulty in pulling them, and avoid using a strong force to pull them.
5) Separate RF cables from power cables. Take proper isolation measures if they have to be placed on the same cable racks owing to the site condition restriction.
6) Correctly fasten all connection parts of the whole system, from the antenna to active interfaces to passive interfaces, and keep electrical interfaces well contacted. Give waterproof treatment to outdoor connection parts.
7) Take lightning protection measures for the antenna and feeder system in accordance with the design requirement. Avoid deforming the antenna feeder where grounding clips are placed, and give waterproof treatment to the feeder.
8) Keep exposed indoor cables in good order. Install PVC troughs or tubes if the exposed cables are more than 1 meter long. Place small passive RF parts such as power splitter in cable troughs.
9) Process both ends of RF coaxial cables as follows:  Keep the same redundant cable length and keep the length of stripped cables to agree with the corresponding connectors.  Use a proper force to cut the jacket layer or insulation layer and avoid damaging the braid shielded net and cores.  Weld cores firmly and smoothly with a proper amount of solder, without solder projections or nodules. Assemble coaxial cables strictly in accordance with the installation specifications.  Keep a moderate length of heat-shrinkable tubes and heat-shrink the tubes evenly when adding heat-shrinkable tubes to the end of cables.
- 17 -

SZZJ-A17F-5S User Manual
 Protect the ends of cables against water and dampness. Use waterproof tape to give waterproof treatment to exposed cable ends. Cut off the end if it is dampened or water-soaked.
7.6. Indoor antenna installation Proper antennas shall be selected according to the site conditions and the requirement. And more than one antenna can be used with the repeater, especially for repeaters equal with or over 20dBm, and 30dBm can be connected with up to 10 antennas in order to send the signals to larger areas or distribute the signals equally. Please consult our professional engineers about the solution if you want to connect more than one antenna. 1) Omni antenna (Indoor ceiling omni antenna or whip antenna), is suitable to be installed in the center and radiate all directions.
2) It is better to use a directional panel antenna or Yagi when the coverage shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space).

7.7. Repeater Installation
7.7.1. Installation Steps 10dBm~30dBm shall be installed in indoor areas only 1) Connect the power supply and the cables properly to the repeater ports. 2) Check again to make sure the repeater is installed firmly and repeater alarm LED must stay green.
7.7.2. Repeater's ports description
1) Outdoor port: connected with the donor antenna by cable. 2) Indoor port: connected with server antenna directly or by cable. 3) DC IN: connected with power supply.
7.7.3. Accessories selection Please pay attention to the two points of "frequency" and "impedance" during the selection of the accessories. All accessories shall support the repeater's frequencies from feeder line, antenna and splitter to combiners etc. For example, the repeater's frequency is GSM900, so all the accessories must support the GSM900 frequency. And the repeater's impedance is 50ohm, so the accessories shall all be 50ohm. To use any other impedance of coax will put an extra load on your repeater, shorten its life span and decrease the system performance.
7.8. Repeater Settings Please check very carefully all cable connections are correct and firm before running operation test and then carry out following tests.

7.9.2. Repeater can not communicate in Power-ON status

SZZJ-A17F-5S User Manual

1) The power is on but it has a signal fluctuation or a flash signal. The phone call can not be achieved.
It shall be caused by the insufficient isolation between donor antenna and serve antenna. Please take below measures:  Firstly check whether the alarm LED is orange. The orange light shows the insufficient isolation.  Secondly adjust the antennas' directions or locations or enlarge the distance between them.  Thirdly reduce the repeater's gain by ATT DIP if the above methods don't work. The following measures can also be tried:  Use the roof of the building to enlarge the isolation (Please try to place the donor antenna and
server antenna in different floors).  Use some obstacles (Such as wall). 2) The repeater's power is on but the phone is not connected into the network and still can not
communicate.
 Reason 1: There are loose or wrong connections in the repeater system.  Solution: Please try to fasten the connections between the different parts of the system.
 Reason 2: The signals received by donor antenna of other operators nearby are too strong. (For example, the other operators' signals are 10 dB stronger than the needed signals.)  Solution 1: Change the direction of donor antenna or its installation position, so that the gap of signal strength is reduced between operators.  Solution 2: Use barriers (like buildings) to block signals of other operators.
3) The repeater has alarm OFF status
 Reason: the repeater breaks down.  Solution: Please check the power adaptor to see if it breaks down or not, then take off the plug and re-plug in, if alarm LED maintains off, the repeater break down is confirmed, then please consult local dealers for warranty.
 Reason 2: There is self oscillation if alarm LED turns red after re-plugging in.  Solution 1: Change the direction or location of donor or server antennas to enlarge the distance.  Solution 2: Use barriers (like buildings) to increase isolation.  Solution 3: Reduce the repeater gain by DIP switch.

FURTHER INFORMATION ON SIGNAL BOOSTER END-USE REGISTRATION

SZZJ-A17F-5S User Manual

CONSUMER BOOSTERS

A subscriber must have the consent of a wireless-services provider to operate a Consumer Signal Booster.

Subscribers may obtain provider consent in a variety of ways. For example, AT&T, Sprint, T­Mobile,

and Verizon Wireless have voluntarily committed to allow their subscribers to use properly certificated

Consumer Signal Boosters (i.e., boosters that meet the new rules) on their networks. Also, a signal

booster manufacturer could seek authorization for use of a particular booster model on behalf of all

subscribers of specific providers. Alternatively, a provider may specify a testing protocol that if satisfied

would result in licensee consent to specific booster models. A subscriber may also seek a licensee's

express consent to operate a signal booster, e.g., by phone call or e-mail.[R11]

Public Notice DA 16-137 [R28] gives listings of Consumer Boosters that have received FCC certification

as of February 2, 2016.

The following selected information about wireless providers' Consumer Booster registration mechanisms

supplements the requirements and information given in Sections 20.21, 22.9, 24.9, 27.9, and the FCC

Signal Boosters website (http://wireless.fcc.gov/signal-boosters/).

· Sprint Nextel will allow consumers to register their signal boosters by calling their toll-free number.

They have already trained their calling center and have designated an engineer to handle inquiries.

They may eventually allow consumers to register on their website but they want to gauge how the

process works via phone first.

· T-Mobile online registration link: (www.T-Mobile.com/BoosterRegistration);

(https://saqat.t-mobile.com/sites/SignalBooster#).

· Verizon's online registration link:

(http://www.verizonwireless.com/wcms/consumer/register-signal-booster.html).

· AT&T will allow online registration and will inform OET Lab with the weblink when it is ready.
