INSTALLING THE BELT CLIP If necessary, attach the belt clip firmly using the two supplied M3 x 6 mm screws (with washers). Note: If the belt clip is not installed, its mounting location may get hot during continuous transmission or when left sitting in a hot environment. Do not use glue which is designed to prevent screw loosening when installing the belt clip, as it may cause damage to the transceiver. Acrylic ester, which is contained in these glues, may crack the transceiver's back panel. CONNECTING AN EARPHONE/ MICROPHONE Connect an earphone/ microphone to the phone jack on the top of the transceiver. Note: ◆ Be sure to connect an earphone/ microphone to the phone jack fully and tightly. If the pin jack of an earphone/ microphone is not inserted fully, a pin contacting error will happen and a noise may occur. ◆ Depending on the sleeve shape of
an earphone/ microphone jack foot, it may be difficult to judge the inserted condition. Before using the radio, confirm the Transmit/ Receive operation with an earphone/ microphone. ◆ To keep the transceiver water resistant, the phone jack cover must remain closed. 3.5 mm plug Phone jack cover 6
