■ Using the HM-165

NOTE:
• NEVER immerse the connector in water. If the connector becomes wet, BE SURE to
dry it before attaching to the transceiver.
• The microphone element is located at the top of the speaker microphone, as shown in
the illustration above. To maximize the readability of your transmitted audio, hold the
microphone approximately 5 ~ 10 cm (2 ~ 4 inches) from your mouth, and then speak
at your normal voice level.
• If the audio sound becomes muffled, remove any water that may be inside the speaker
grill and/or microphone hole.
• The DSC alarms sound from the transceiver, even while the speaker microphone is attached.

NOTE: KEEP the jack cover attached when the speaker microphone is not used. If the
