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.
●
Private call: It is a voice call between one individual user and
another individual user.
●
Group call: It is a voice call between one individual user and a
predefined group of users. All parties in the group can communicate
with each other.
●
All call: It is a one-way voice call from any user to all users on a
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; but in group call, the radio will
make a call to all parties involved when calling back. And you cannot call
back in an all call.
Here takes the private call between Radio A and Radio B for example:
1. Radio A and B select the same digital channel.
You may preset a regular private call/group call/all call contact for
each digital channel via your dealer.
2. Radio A holds down the
PTT
key to initiate a call.
3. Radio A can talk to the microphone when the LED indicator on the
radio glows red and release the
PTT
key to finish talking.
4. Radio B can receive the call without any operation
.
When receiving,
the LED indicator glows green.
5. Radio B can hold down the
PTT
key to talk when the LED indicator on
the radio is glowing orange.
6. Radio A can receive the call without any operation. When receiving,
the LED indicator glows green.
7. Radio A can hold down the
PTT
key to talk when the LED indicator on
the radio is glowing orange.
The Call Hang Time (the duration of LED indicator
glowing orange) is preset by your dealer.
Call on Analog Channel
The calling operations on the analog channel are the same as that 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.
