LC90 is powered by 2*18650 rechargeable lithium battery. A USB-Type-C cable is supplied in the package. Press and hold the( )button to power on.To shutdown the radio,press and hold the same button.
2.Charging battery
To charge the battery,connect the Type-C cable to 5V power adapter,you can use any mobile phone charger,the mobile quick charge protocol ensures that the output voltage of the charger will adjust to 5V when charging to radio,but DO NOT USE THE CHARGER OF IPAD OR COMPUTER! Note:The charging might take much longer to complete if the radio is playing while charging.
3.Bluetooth playback
Press the BT() Key to make the radio enter Bluetooth mode. Open your device' s Bluetooth setting,and active the pairing mode,the device scans for Bluetooth devices. When the radio is found,your Bluetooth device shows its name "Choyong-LC90" ,select the radio and connect it.

12

(next,previous,pause...ect). The connection will be restored automatically when both devices are in range and the radio in Bluetooth mode.
4.Software update
There may be software release to upgrade features of the radio from time to time.Check the update regularly to keep your radio up to date with the latest software. Caution:Do not do any operation during the upgrade progress!!! Or the radio will be damaged!
5.Telescopic antenna assist Middle Wave
An auxiliary middle wave receiving circuit is integrated in the radio,you can try to use telescopic antenna to increase the MW signal strength and to improve the performance of SNR ,especially effective outdoors.
6.About MW(medium-wave)
1.This radio is equipped with a built-in ferrite bar MW antenna, and also has a telescopic antenna to assist in MW reception. When receiving medium waves, you can try to extend the telescopic antenna to improve the reception capability. 2.This radio can be connected to an external antenna. You can use a 3.5mm headphone jack and a longer wire to modify it into an external antenna, which helps in
13

receiving medium and short waves and FM. It is important to note that any pin of the 3.5mm jack can serve as a signal pin, allowing you to design your own external antenna. However, it does not support connecting to active MW antennas. Q: Why is the medium-wave reception performance relatively weak? A: Due to the interference of LCD, the medium wave reception performance of this radio is indeed a bit weak. You can pull out the telescopic antenna to enhance the reception performance of MW (we have designed a circuit to enhance the reception of MW with telescopic antenna), or try it outdoors to see if the medium wave reception of this radio is really defective.Indoors, we still recommend connecting to Wi-Fi to listen to online radios.
7.How to adjust the meter band and bandwidth
1.The first knob of the radio is used to adjust the meter band. In the SW playback interface, simply press the middle position of the first knob once. When you see the meter band value blinking, you can adjust the meter band by turning the knob. 2.The second knob of the radio is used to adjust the bandwidth. In the SW/MW playback interface, simply
14

press the middle position of the second knob once. When you see the bandwidth value blinking, you can adjust the bandwidth by turning the knob.

1.ON/OFF
Press 2 seconds to turn the radio ON/OFF,press 5 seconds till the white screen appeared to force restart the radio.
1.1 Received the radio and found that it had no power, what should you do
To meet the requirements of air transportation, the voltage of the 18650 battery should not exceed 3.65V. The battery voltage of the radio you received is relatively low. I suggest you charge it for a while before using it. Due to the actual capacity of the battery being about 5400mAh, it will require a longer charging time. It's recommended that you charge it before going to bed at night, so that the radio will be fully charged the next morning.
