D Transmitting an Emergency Call When [Emergency] (described in the instruction manual) is held down for the specified time period, the emergency signal is transmitted once or repeatedly* on the emergency channel. When no emergency channel is specified, the signal is transmitted on the operating channel. * W hen the Repeat Cancel function is ON, the transceiver cancels repeat calling after receiving an acknowledgement. When the Repeat Cancel function is OFF, the transceiver continues to call according to the number of repeat cycles, even after receiving an acknowledgement. Individual or Talkgroup call types of emergency calls can be preset. 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. The emergency call can be transmitted without sounding beeps or changing the LCD display, depending on the preprogramming. (Silent operation) The transceiver can also be programmed to keep the microphone open during an emergency call, allowing other stations to monitor the situation. Ask your dealer for details.
