dPMR ™ OPERATION
4-4
Transmitting a call
dPMR
™
operation allows you to make a call to a spe-
cific station (Individual call) or to a particular group
(Talkgroup call). Other digital mode transceivers on the
channel will not receive a call that does not match their
individual or talkgroup ID and/or CC.
Transmitting a Voice call D
Rotate [ROTARY SELECTOR], or push one of the
q
memory channel keys, [MR-CH 1] to [MR-CH 4], to
select a desired channel, Individual ID or Talkgroup
ID, depending on the presetting.
Push [PTT] or [Call] to make a Voice call.
w
• The status indicator lights red while transmitting.
• The status indicator fast blinks orange.
• After an acknowledgement is received, the status indica
-
tor slowly blinks orange in the Audible mode, or it goes
OFF when no acknowledgement is received.
Hold down [PTT], then speak at your normal voice
e
level.
• The status indicator lights red while transmitting.
Release [PTT] to receive.
r
After you finish your communication, push [Clear] to
t
send a ‘Disconnect’ signal to terminate the connec-
tion.
Transmitting an Emergency call D
When [Emergency] is held down for the specified time
period, the emergency signal (digital command) is trans-
mitted once or repeatedly* on the specified emergency
channel. When no emergency channel is specified, the
signal is transmitted on the operating channel.
* When the Repeat Cancel function is ON, the transceiver
cancels repeating after receiving a return signal.
When the Repeat Cancel function is OFF, the trans-
ceiver repeats calling according to the number of re-
peat cycles, even after receiving
a return signal
.
Individual or Talkgroup call types of emergency calls
can be pre-set. If the call type is not preset, the default
or selected call type is used.
If you want to cancel the emergency call, hold down
[Emergency] again before transmitting the call.
If your transceiver is programmed for Silent operation,
you can transmit an Emergency call without the beep
sounding and the status indicator lighting.
The transceiver can also be programmed to keep the
microphone open during an emergency call, so others
can monitor the situation.
IMPORTANT: We recommend you set an emergen-
cy channel individually to provide the certain emer-
gency call operation.
NOTE: If the Digital Request Ack function is activat-
ed, the transceiver transmits the emergency call with
a request to send back a return signal.
