Receiving
When the RSM is connected to the radio accessory
connector, the radioÕs speaker is muted, and the audio is
only heard from the RSM speaker. Similarly, when a
secondary receiver audio accessory is plugged into the
3.5mm audio jack (MDHMN9053), audio to the RSM is
rerouted to the secondary accessory.
Transmitting
Connecting the remote speaker/microphone to the radio
does not disable the radioÕs microphone and PTT.
Removing the RSM
Turn the radio off before removing the RSM from the radio
accessory connector. Remember to reattach the radio
accessory connector seal to the side of the radio when an
accessory is not being used.
Service
Other than the cable assembly, the MDHMN9052 and
MDHMN9053 Remote Speaker/Microphones are not
repairable. Order replacement speaker/microphones as
necessary. The replacement Speaker/Microphone Cable
Kit, HKN9055, includes the replacement cable and
installation instructions.
