INSTALLING THE BELT CLIP
If necessary, attach the belt clip 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: To keep the transceiver water resistant,
the phone jack cover must remain closed.
