Talk back function
The talk back function allows you to select the same call
mode (Analog or Digital) and/or call type (Individual or Talk-
group) as the received call.
When the talk back timer is set to 0 seconds, this function is
not activated. Ask your dealer for details.
If this function is cancelled by pushing
[Digital Button]
or any
key on the 10-key keypad, or after the talk back timer period
has passed, your transceiver automatically returns to the de-
fault call mode and type.
If the received call is a digital signal, the talk back function is
activated only for Voice Call, Call Alert, Status Message and
Message.*
* Depending on the presetting, the talk back function may be acti-
vated only for Voice Call.
When the channel type is “Mixed-Analog”
After receiving a digital signal, you can select the digital call
mode by pushing
[PTT]
before or during the talk back timer
period.
When the channel type is “Mixed-Digital”
After receiving an analog signal that can release the mute,
you can select the analog call mode by pushing
[PTT]
before
or during the talk back timer period.
When the channel type is “Mixed-Digital” or “Digital”
After receiving a digital signal, you can select the same call
digit mode to transmit by pushing
[PTT]
before or during the
talk back timer period.
NOTE:
When this function is not activated, the transceiver trans-
mits an analog signal on a “Mixed-Analog” channel, and
transmits a digital signal on a “Mixed-Digital” channel.
• The transceiver receives both analog and digital signals on the
“Mixed-Analog” and “Mixed-Digital” channels, regardless of the
function's setting.
This function is usable in transceivers whose revision number
is 2.9 or later. Ask your dealer for details.
