Getting ‘on air’ with your Radioddity GD-73 v1.0
Initiating a DMR group call
All radios that you wish to communicate with must be on the same group.
1. Select the desired channel using the and buttons. Programming channel
names with a name that associates with the Talkgroup is useful to facilitate this.
2. Hold the radio vertically, about 2.5 to 5cm from your mouth
3. Now press the PTT key to transmit. The status LED lights up red. The group name
appears on the display
4. Once finished speaking, release the PTT button to return to receive. If a response
is not heard within a predetermined time, the call is terminated.
5. When the call is answered, you will see the status LED light up green.
6. On the display you will see:
• in the top line ‘Group’
• in the middle line the DMR-ID of the caller
• in the bottom line ‘Calling’ is displayed, followed by ‘end call’ if the channel
was not previously active.
7. If the Channel Free Indication Tone feature is enabled, you will hear a short beep
as soon as the transmission has finished.
8. When the group call is over, the display changes back to the previous display.
9. A group call can also be initiated from the contacts.
