IDAS OPERATION
Auto CH Reserve function
■
If enabled, this feature is effective when a subscriber attempts
to push [PTT] while the site is in an “All Trunks Busy” status,
and/or is still “Receiving a Downlink” at the time the [PTT] is
pushed.
In the event of an “All Trunks Busy” condition, and/or a “Re-
ceiving a Downlink” condition, a quick [PTT] push results
in the transceiver going into a waiting for an open repeater
mode. When an open repeater signal is received by the trans-
ceiver, the transceiver handshakes and holds the channel for
the preprogrammed time period. After receiving a handshake
beep, the transceiver will hold the channel for this period be-
fore it releases it. The operator must then key up their trans-
ceiver to communicate. Failure of the operator to push [PTT]
before this timer expires results in a loss of the channel grant
and another push of the [PTT] will be required.
When the preprogrammed CH Reserve Timeout timer elaps-
es, the transceiver returns to its default state.
Talk Back function
■
The Talk Back function allows you to select the same call type
(Individual or Talkgroup) for 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 a 10-key keypad, or after the Talk Back timer period
has passed, the transceiver automatically returns to the de-
fault call 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 is activated
only for Voice Call.
