40rAdio A cceSS numBer (rAn)RAN is a new signaling system designed only for digital radiocommunications. The operation is the same as the analogQT/ DQT signaling.When a channel is set up with a RAN, squelch will only openwhen a call containing a matching RAN is received. Likewise,signals that you transmit will only be heard by parties whoseRAN signaling matches your transceiver.If a call containing a different RAN is made on the samechannel you are using, squelch will not open and you will nothear the call. This allows you to ignore (not hear) these calls.optionAl SignAlingYour dealer may also program several types of option signalingfor your transceiver channels.2-tone Signaling: 2-tone Signaling opens the squelch only whenyour transceiver receives a call containing matching 2 tones.DTMF Signaling: DTMF Signaling opens the squelchonly when the transceiver receives a call containing amatching DTMF code. Refer to “DTMF (DUAL TONE MULTIFREQUENCY) CALLS” on page 34.FleetSync Signaling: Refer to “SELCALL (SELECTIvE CALLINg)”on page 30.NXDN ID Signaling: NXDN ID is an optional signaling systemavailable only for digital communications.viBrAtorWhen an optional external vibrator is installed, the vibratorfunction will alert you when an optional signaling call isreceived.Press the key programmed as Vibrator, or access the Vibratorfunction through the Menu {page 23}, to turn the Vibratorfunction ON and OFF.• When activated, the icon appears on the display.
