Receiving
When the RSM is connected to the radio accessory jack, the radio speaker
is muted and the audio is heard from the RSM. Similarly, when a secondary
audio accessory is plugged into the 3.5 mm audio jack (MDPMMN4021),
audio to the RSM is rerouted to the secondary accessory.
Transmitting
To transmit using your RSM:
1
Press and hold the Push-To-Talk (PTT) button on the RSM.
2
Speak into the RSM.
3
Release the PTT button when finished.
NOTE:
Connecting the RSM to the radio does not disable the radio
microphone and PTT.
Removing the RSM
Turn the radio off before removing the RSM from the radio. Remember to
reattach the radio accessory connector seal to the side of the radio when an
accessory is not being used.
Service and Warranty
Other than the replaceable cable assembly and clip, the MDPMMN4021 and
MDPMMN4027 Remote Speaker Microphones are not repairable. The
RSMs are covered under the standard Motorola Solutions one year limited
warranty.
