Transmission Management
You can initiate a private call, group call or all call (your radio
must be programmed to allow you to use the all call service)
through the same operations on digital channel. When calling
back, the radio will make a call to the calling party in private call
and all call (your radio must be programmed to allow you to call
back in an all call); but in group call, the radio will make a call to
all parties involved when calling back.
Here we take the private call as example to illustrate the call
process:
1. User A and B select the same digital channel.
2. User A holds down the PTT key to initiate a call.
You preset a regular private call/group call/all call contact
for each digital channel via your dealer.
3. User A can talk to the microphone when the LED indicator on
the radio glows red.
4. User A releases the PTT key to finish talking.
User A can hold down the PTT key to talk when the LED
indicator on the radio is glowing orange.
When receiving, the LED indicator on the radio glows green.
5. User B can receive the call without any operation. When
receiving, the LED indicator glows green.
6. User B can hold down the PTT key to talk when the LED
indicator on the radio is glowing orange.
Note: The duration of LED indicator glowing orange (Call Hold
Time) is preset by your dealer. If neither one talks before this
duration expires, the call will end.
Calling on Digital Channel
Calling on Analog Channel (No Signaling)
On the analog channel without signaling, the calling operations
are the same as on the digital channel. The difference is that
the called parties are all the users on the channel, rather
than the preset contact for the channel.
Please refer to the corresponding Feature Book for calling
operations on the analog channel with signaling.
