The device does not use the provisions of 47CFR 15.323 (c) (6), random waiting mechanism is not used in this system. 2. The provisions of 47CFR 15.323 (c) (10) and 47CFR 15.323 (c) (11) are not used to extend the range of spectrum occupied over space or time for the purpose of denying fair access to spectrum to other devices. 3. Only the handset will act as the initiating device, which will initiate the establishment of the duplex connection. 4. The device complies with the provisions of 47CFR 15.319(f). The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude transmission of control and signaling information or use of repetitive codes used by certain digital technologies to complete frame or burst intervals. The following table explains the reaction of device in case of either absence of information to transmit or operational failure after a connection of its companion device is established. Circumstances Reaction of Base Unit Reaction of Handset 1 Switch-off companion device NA NA 2 On hook by companion device B NA 3 Remove power from companion device B A 4 Switch-off device NA NA 5 On hook device NA C 6 Remove power from device A C A – Connection is terminated and, transmission ceases.

INTERTEK TESTING SERVICES FCC ID: EW780-7764-00 RF exposure info - 1 of 1 For Maximum Permissible Exposure (MPE) evaluation of the base unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65. For the base unit of tested model of TL92271, the maximum field strength measured (FS) was 117.5 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. And the maximum source-based time-averaging duty factor in four-handsets operation is 20.8%. From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The radiated power (EIRP) = (FS*D) 2 / 30 = 168.70 mW The radiated (EIRP) source-based time-averaging output power = (168.70 * 0.208) mW = 35.09 mW The power density at 20 cm from the antenna = EIRP / 4πR 2 = 0.0070 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the base unit at least 20cm from nearby persons.”
