5TK-7102HOPERATING FEATURES• Key lockPressing this key causes the transceiver to accept entryof only the [Vol Up/Down]*, [Key lock], Microphone [PTT],[Monitor], [Emergency], and [Power] keys.* Programmable• MonitorUsed to release signalling (press once) or squelch (pressand hold for approximately two seconds) when operating asa conventional. It is also used to reset option signalling.• Scan ON/OFFPress this key starts scanning. Pressing this key stopsscanning.• Talk aroundPress this key, the transceiver uses the receive fre-quency and the tone for transmission.The operator can call the other party directly (without re-peater). Press this key again, the talk around function goesoff.• Temporary deleteThe “Add” channel contained in the scan sequence, and“Delete” channel is not contained. In the scan mode, thiskey switches the channel delete temporarily (Press and holdfor approximately one second).When the transceiver is turned off, the transceiver exitsthe scan or switches the scan function off.• NoneSounds error operation beep, and no action will occur.Use this function when the transceiver is required to bemore simple operated.4. Scan Operating SCAN start conditionTwo or more channels must be added to all channels thatcan be scanned. The transceiver must be in normal receivemode (PTT off).When you activate the key programmed to the scan ON/OFF function, the scan starts. The indicator next to the pro-grammed key LED blinks. Scan stop conditionThe scan stops temporarily if the following conditions aresatisfied.1) A carrier is detected, then QT/DQT matches on channelsfor which receive the QT/DQT is set by the programmingsoftware.2) A carrier is detected on the channels for which receivingQT/DQT is not set by the programming software or whenthe monitor (signalling cancel) function is activated. Revert channelThe revert channel is used to transmit during scanningand set by the programming software (KPG-70D).1) Selected channelThe transceiver reverts to the channel before scanning orthe channel that you changed during scan.2) Selected with talkbackThe transceiver reverts to the selected channel prior toscan initiation.However, if a call is received on a channel other then theselected channel and PTT is pressed before scanning re-sume, the transceiver “talks back” on the current receivechannel. Scan endWhen you press the key programmed to the scan func-tion during scan mode, the scan ends.The indicator next to the programmed key LED turns off. Temporary deleteIt is possible to delete channel temporary during scan.When scan stops on unnecessary channel for example byinterference of the other party, activate the delete function(for example press and hold the key for approximately onesecond), then that channel is deleted temporarily and scanre-start immediately.The temporary deleted channels return to pre-set delete/add channels, when the transceiver is turned off or the scanfunction is switched off.5. Details of Features Time-out timerThe time-out timer can be programmed in 30 secondsincrements from 30 seconds to five minutes and off. If thetransmitter is transmitted continuously for longer than theprogrammed time, the transmitter is disabled and a warningtone sounds while the PTT button is held down. The warn-ing tone stops when the PTT button is released. PTT IDPTT ID provides a DTMF ANI to be sent with every timePTT (beginning of transmission, end of transmission, orboth).You can program PTT ID “on” or “off” for each channel.The contents of ID are programmed each Radio.The timing that the transceiver sends ID is program-mable.BOT : DTMF ID (Beginning of TX) is sent on beginning oftransmission.EOT : DTMF ID (End of TX) is sent on end of transmis-sion.Both : DTMF ID (Beginning of TX) is sent on beginning oftransmission and DTMF ID (End of TX) is sent on end oftransmission.
