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.
D Attaching the HM-213
1. Turn OFF the transceiver.
2. Insert the speaker microphone connector into the [SP/MIC] connector and securely
screw it, as shown below.
L Be careful not to cross-thread the connection.
CAUTION: Attach the speaker microphone's connector securely to
prevent accidental loss, or water intrusion into the connector.
NOTE: KEEP the transceiver's [SP/MIC] cover 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.
