4 dPMR™ OPERATION Transmitting a call dPMR™ operation allows 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 that does not match their individual or talkgroup ID and/or CC. DDTransmitting a Voice call qqRotate [ROTARY SELECTOR], or push one of the memory channel keys, [MR-CH 1] to [MR-CH 4], to select a desired channel, Individual ID or Talkgroup ID, depending on the presetting. wwPush [PTT] or [Call] to make a Voice call. • The status indicator lights red while transmitting. • The status indicator fast blinks orange. • After an acknowledgement is received, the status indicator slowly blinks orange in the Audible mode, or it goes OFF when no acknowledgement is received. eeHold down [PTT], then speak at your normal voice level. • The status indicator lights red while transmitting. rrRelease [PTT] to receive. ttAfter you finish your communication, push [Clear] to send a 'Disconnect' signal to terminate the connection. DDTransmitting an Emergency call When [Emergency] is held down for the specified time period, the emergency signal (digital command) is transmitted 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 transceiver repeats calling according to the number of repeat 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 emergency channel individually to provide the certain emergency call operation. NOTE: If the Digital Request Ack function is activated, the transceiver transmits the emergency call with a request to send back a return signal. 4-4
