Remark: 1. This is a C2PC(FCC) or C4PC(IC) application to evaluate the antenna(s) used for the module: AP72598V transmit simultaneously with Bluetooth module: QCC5181 in specific hosts (Model No.: MA710, MA7100HP, MA9100HP). 2. The Bluetooth function of module AP72598V will be disabled via software. 3. Electrically identical in RF signal characteristics in transmitting singly. So only re-test radiated emissions transmitting simultaneously.

1.1.1.1 RF Exposure Compliance Requirement for FCC
FCC requirement: Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 20cm normally can be maintained between the user and the device.

1.1.1.2 RF Exposure Compliance Requirement for IC
The EUT shall comply with the requirement of RSS-102 section 6.6. RF exposure evaluation is required if the separation distance between the user and/or bystander and the device's radiating element is greater than 20 cm, except when the device operates as follows: · below 20 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1 W (adjusted for tune-up tolerance);
· at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 4.49/0.5 W (adjusted for tune-up tolerance), where  is in MHz;
· at or above 48 MHz and below 300 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up tolerance);
· at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 x 0.6834 W (adjusted for tune-up tolerance), where  is in MHz;

· at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 5 W (adjusted for tune-up tolerance).
In these cases, the information contained in the RF exposure technical brief may be limited to information that demonstrates how the e.i.r.p. was derived.
