Motorola XPR 4300 ユーザーズマニュアル

Once the channel, 
subscriber ID, or group 
ID is set, you can 
proceed to receive and 
respond to calls. 

NOTE: The green LED lights up while the radio is transmitting 

and blinks rapidly when the radio is receiving a 
privacy-enabled call.

To unscramble a privacy-enabled call, your radio must 
have the same Privacy Key (programmed by your 
dealer) as the transmitting radio (the radio you are 
receiving the call from). See Privacy on page 20 for 

more information. 

To receive a call from a group of users, your radio must be 
configured as part of that group.

Procedure:
When you receive a Group Call:

The green LED blinks. 

 

If the Channel Free Indication feature is enabled, you 

will hear a short alert tone the moment the transmitting radio 
releases the PTT button, indicating the channel is free for 
you to respond.

Press the PTT button to respond to the call. The green LED 
lights up.

Wait for the Talk Permit Tone to finish (if enabled) and speak 
clearly into the microphone.

Release the PTT button to listen.

If there is no voice activity for a predetermined period of 
time, the call ends.

See Making a Group Call on page 11 for details on making a 
Group Call.
