IDAS OPERATION

Receiving a call (continued)
D
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 setting details.
If this function is cancelled by pushing [Digital Button] or any
other keys, or after the talk back timer period has passed,
the transceiver automatically returns to the default 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 preprogramming, the talk back function may be
activated for only 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
type for the received call (Individual or Talkgroup), by pushing
[PTT] before or during the talk back timer period.
NOTE:
When the Talk Back function is not activated, the trans-
ceiver transmits 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 this
function.
