Turn the transceiver power OFF
when connecting the HM-165.
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 at the top of the
speaker-microphone, as shown in the diagram above. To
maximize the readability of your transmitted signal (voice),
hold the microphone approx. 5 to 10 cm (2 to 4 inch) from
your mouth, and speak in a normal voice level.

■ 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] cap at-
tached when the speaker-microphone is not in use. If the
cap 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.
CAUTION: Attach the speaker-microphone's
connector securely to prevent accidental
loss, or water intrusion in the connector.
