Call Services
After the radio is powered on, you can make and receive calls. To ensure
optimal volume of the receiving radio, keep the microphone about 2.5 to
5 centimeters away from your mouth when transmitting.
The types of calls you may initiate are listed below:
●
Private call: A call made to a private contact.
●
Group call: A call made to the group contacts.
●
All call: A call made to all the contacts on the current channel.

Call on Digital Channel
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 for radios.
Users can request the dealer to preset a regular private call/group
call/all call contact for each digital channel.
2. User A holds down the PTT key to initiate a call.
User A can talk to the microphone when the LED indicator on the
radio glows red and release the PTT key to nish talking.
3. User B can receive the call without any operation. When receiving,
the LED indicator glows green.
User B can hold down the PTT key to talk when the LED indicator on
the radio glows orange.
4. User A can receive the call without any operation. When receiving, the
LED indicator glows green.
User A can hold down the PTT key to talk when the LED indicator on
the radio glows orange.
The duration of LED indicator glowing orange (Call Hold
Time) is preset by your dealer.
