comes wet, be sure to dry it BEFORE attaching it to the trans-
ceiver.

speaker-microphone, as shown in the diagram above. To

I Attachment

Turn power OFF before attaching the speaker-microphone.
Then, insert the speaker-mic connector onto the [SP MIC]
connector and carefully screw it tight, as shown in the dia-
gram below. Be careful not to cross-thread the connection.
IMPORTANT: KEEP the transceiver's [SP MIC] connector
cap attached when the speaker-microphone is not in use.
If the cover is not attached, water will get into the trans-
ceiver. Moreover, the terminals (pins) will become rusty, or
the transceiver will function abnormally if the connector has
become wet.
CAUTION: Attach the speaker-microphone's
connector securely to prevent accidental
loss, or water intrusion in the connector.
