DESCRIPTION
The MDHMN9052 and MDHMN9053 Remote Speaker/
Microphones (RSMs) provide a convenient means of com-
municating by having a speaker, a microphone, and a PTT
in a single, hand-held or clip-on accessory. The
MDHMN9053 Remote Speaker/Microphone includes a
noise cancelling port that reduces background noise during
transmission. It also includes a 3.5 mm audio jack (located
on opposite side of RSMÕs PTT) to accept secondary
receiver audio accessories.
OPERATION
Attaching the RSM to the Radio
1. Turn the radio off.
2. Remove the universal connector seal from the side of
the radio and attach the RSM.
3. Turn the radio on.
Wearing the RSM
(See Figure 1)
For optimum performance
from your RSM, wear the
radio and RSM so that the
accessory cord will not
cross over or touch the
antenna. Also, try to wear
the radio and accessory
combination fairly close to
each other to avoid strain on
the accessory connector.

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.
