3 BASIC OPERATION ■ Emergency Call When [Emergency] is pushed for the specified time period*, the emergency signal is transmitted once, or repeatedly, on the specified emergency channel. A repeat emergency signal is automatically transmitted until the transceiver receives an acknowledgement signal, or you turn the transceiver power OFF. When no emergency channel is specified, the signal is transmitted on the previously selected channel. If you want to cancel the emergency call, push and hold [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 LED indicator lighting. IMPORTANT: It is recommended to set an emergency channel individually to provide the certain emergency call operation.
