to your shirt or collar, etc.

Turn the transceiver power OFF 
when connecting the HM-165.

NEVER immerse the connector in water. If the connector 
gets wet, be sure to dry it BEFORE attaching it to the trans-
ceiver.

NOTE: The microphone is located at the top of the 

speaker-microphone, as shown above. To maximize the 
readability of your transmitted signal (voice), hold the mi-
crophone approx. 5 to 10 cm (2 to 4 inches) from your 
mouth, and speak in a normal voice level.

NOTE: When the speaker-microphone is connected to 
the transceiver, the noise cancellation does not work.

Turn power OFF before attaching the speaker-microphone.
Then, insert the speaker-mic connector into the 

[SP MIC] 

connector and carefully screw it tight, as shown 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 
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.

CAUTION: Attach the speaker-microphone’s 
connector  securely  to  prevent  accidental 
loss, or water intrusion in the connector.

Detaching:
Rotate the 

[SP MIC] cap counter-

clockwise (q), then detach it (w).

Attaching:
Attach the 

[SP MIC] cap (q), then 

rotate it clockwise completely (w).
