HM-167 descriptions ■
NEVER immerse the connector in water. If the connector
becomes wet, be sure to dry it BEFORE attaching it to the
transceiver.
NOTE: The microphone is located near the top of the
speaker-microphone, as shown in the illustration above.
To maximize the readability of your transmitted signal
(voice), hold the microphone approximately 5 to 10 cm
from your mouth, and speak at a normal voice level.
Attachment ■
Turn power OFF before attaching the speaker-microphone.
Then, insert the speaker-microphone’s connector into the
[SP MIC] connector and carefully screw it tight, as shown in
the diagram below. Be careful not to cross-thread the con-
nection.
IMPORTANT: KEEP the transceiver’s [SP MIC] cap attached
when the speaker-microphone is not used. If the cover is not
attached, water will get into the transceiver. Moreover, the
terminals (pins) will become rusty, or the transceiver will
function abnormally if the connector gets wet.
Set the triangle mark K
to the back side.
CAUTION: Attach the speaker-
microphone’s connector securely
to prevent accidental dropping, or
water intrusion in the connector.
