2 PANEL DESCRIPTION Programmable function keys (Continued) The following functions can be assigned to the [Upper], [Lower] and [Emer] programmable function keys. SCAN Push to start and cancel scanning. • When the scan started with the Power ON Scan or Auto Scan function, push to pause the scan. The paused scan resumes after the specified time period has passed. PRIORITY A CHANNEL, PRIORITY B CHANNEL Push to select the Priority A or Priority B channel. PRIORITY A CHANNEL (REWRITE), PRIORITY B CHANNEL (REWRITE) ➥➥Push to select the Priority A or Priority B channel. ➥➥Hold down [Prio A (Rewrite)] or [Prio B (Rewrite)] for 1 second to assign the operating channel to the Priority A or Priority B channel, respectively. MEMORY CHANNELS 1, 2, 3, 4 Push to directly select memory channel 1, 2, 3 or 4, if programmed. LONE WORKER (p. 3-13) ➥➥Hold down for 1 second to turn ON the Lone Worker function. • When the Lone Worker function is turned ON, and no operation is performed for the specified time period, the Emergency function is automatically turned ON. ➥➥Push to turn OFF the Lone Worker function. MONITOR, MONITOR (AUDIBLE) ➥➥Push to turn the CTCSS (DTCS) or 2/5-tone squelch Mute ON or OFF. • Only during LMR operation, push to open any squelch functions, or deactivate any mute functions. • Only during PMR operation, push to activate one or two of the following functions on each channel. - Hold down to unmute the channel (Audible mode). - Push to mute the channel (Inaudible mode). - Push to send a 'reset code' after the communication is finished. NOTE: The unmute condition may automatically return to the mute condition, after a specified time period. ➥➥Depending on the presetting, holding down this key for 1 second cancels a scan. LOCK Hold down to electronically lock all programmable keys except [Moni(Audi)], [Call] (including Call A and Call B), [Emergency], [Surveillance] and [Lone Worker]. HIGH/LOW (p. 3-12) Select the transmit output power level temporarily or permanently, depending on the presetting. TALK AROUND ➥➥Hold down for 1 second to turn ON the Talk Around function. • The Talk Around function equalizes the transmit frequen- cy to the receive frequency for transceiver-to-transceiver communication. ➥➥Push to turn OFF the Talk Around function. DTMF AUTODIAL Push to transmit a programmed DTMF code. RE-DIAL Push to transmit the last-transmitted DTMF code. NOTE: TX memories are cleared after turning OFF the transceiver. WIDE/NARROW Push to select the IF bandwidth between Wide, Mid* or Narrow. *Depending on the presetting, the Mid channel width may not be selectable. CALL, CALL A, CALL B Push to transmit a 2/5-tone code. • Tone call transmission may be necessary before you call another station, depending on your signalling system. • [Call A] and/or [Call B] keys may be selectable when your system employs selective 'Individual/Group' calls. EMERGENCY Hold down for specified time period to transmit an emergency call. • The emergency call transmits with beeps, and the status indicator lights red. • The transceiver can transmit an emergency call without the beep sounding and the status indicator lighting. • If you want to cancel the emergency call, hold down the key again before transmitting the call. • The emergency call is transmitted one time only, or repeat- edly until receiving an acknowledgement signal, or until the power is turned OFF. When a matched 5-tone code signal is received, the emergency function can be cancelled, depending on the presetting. (PMR operation only) 2-6
