dPMR™ OPERATION
7-2
The transceiver provides digital Private Mobile
Radio (dPMR™) operation that meets the 6�25 kHz
bandwidth requirements for narrow band operation�
This increases the efficiency of channel allocation and
use of the spectrum�
NOTE:
In the dPMR™ mode, BIIS 1200 operation is
disabled�
dPMR™ operation enables you to make a call to a
specific station (Individual call) or to a particular group
(Talkgroup call)� Other digital mode transceivers on
the channel will not receive a call whose ID or code
does not match their Individual or Talkgroup ID and/or
CC*�
D
General
The target ID (Individual ID or Talkgroup ID) and TX
CC* are preset to a channel� To make a call, you
should select the desired channel that your target
station is set to�
• When no acknowledgement is received
After making an Individual call, the transceiver waits
for an acknowledgement for a preset period of time�
If no acknowledgement is received, the transceiver
automatically repeats the call 4 times (default)�
However, when no acknowledgement is received
after the fourth call, an error beep sounds and the
transceiver automatically returns to the Standby
mode�
* You can select the desired CC in only the Conventional
channel�
NOTE:
When the “Called Party Check” item is
OFF, the communication is established even if no
acknowledgement is received in the Conventional
channel�
