■ Attachment

Attach the connector of the speaker-microphone into the [SP MIC]
jack on the transceiver and tighten the screw.

IMPORTANT: KEEP the [SP MIC] jack cover attached to the
transceiver when the speaker-microphone is not in use. (p. 3)
Water will not get into the transceiver even if the cover is not at-
tached, however, the terminals (pins) will become rusty, or the
transceiver will function abnormally if the connector becomes
wet.

CAUTION: Attach the 
[SP MIC] jack securely to 
prevent accidental drop-
ping, or water intrusion in 
the jack.
