7TK-860G/862G• Display character (TK-860G only)This key switches the LCD display between the groupand channel number and the group and channel name.• Emergency (M market models only)Pressing this key for longer than 1 second causes thetransceiver to enter the emergency mode. The transceiverjumps to the programmed "Emergency the group and chan-nel" and transmits for 25 seconds.The transceiver disables mic mute while transmitting.After finishing transmission, the transceiver receivers for 5seconds. The transceiver mutes the speaker while receiv-ing. Following the above sequence, the transceiver contin-ues to transmit and receive.• Group up/down (TK-860G only)When the key is pressed each time, the group number tobe selected is incremented/decremented and repeats if heldfor one second or longer.• Home channelPress this key once, the channel switches to the pre-pro-grammed home channel.• Horn alertIf you are called from the base station using 2-tone/DTMFwhile you are away from your transceiver, you will bealerted by the vehicle horn or some other type of externalalert. To turn the horn alert function on , press this key. Aconfirmation tone sounds, (and the display shows "HA" onthe LCD * 1).If this key is pressed again, the horn alert function isturned off.*1 : TK-860G only.• Key lockPressing this key causes the transceiver to accept entryof only the [Vol Up/Down], [Key lock], [PTT], [Monitor A],[Monitor B], [Monitor C], [Monitor D], and [Emergency] keys.• MonitorUsed to release signalling or squelch when operating as aconventional. It is also used to reset option signalling.• Operator selectable tone (K market models only)This key switches the pre-set decode QT/DQT and en-code QT/DQT to OST (Operator Selectable Tone) tone pair.Press this key, the transceiver enters to OST selectmode. In this mode, the display shows "OFF" and the opera-tor can select one of the OST tone pair using the channel up/down key. The display shows "TONE **" and tone pair No.** is selected.Press OST key again, the transceiver exits from the OSTselect mode.16 kinds of tone pair for OST can be programmed byKPG-56D. OST is useful to access the repeater with sameradio frequency and different tone (QT/DQT).OPERATING FEATURES• Public addressPublic address amplifies the microphone audio, and out-puts it through a PA speaker. PA is activated by pressingthis key. A confirmation tone sounds, (and the displayshows "PA" *1 ). PA can be activated at anytime (scanning ornon-scanning).The RADIO continues to scan & receive calls while in PAmode. Pressing PTT activates PA, and will override an in-coming call at anytime; however, no RADIO transmissiontakes place.If this key is pressed again, a confirmation tone willsound, (the display will return to the normal channel orSCAN display * 1 ), and the PA function will turn off.*1 : TK-860G only.• RedialIf you press this key when the group/channel is dis-played, the last transmitted DTMF code will appear on thedisplay. Pressing the PTT switch at this time will transmitthe displayed DTMF code.• Scan (TK-860G only)Press this key starts scanning. Pressing this key stopsscanning.• Scan del/add (TK-860G only)This key switches the currently displayed channel be-tween "Delete" and "Add".The "Add" channel contained in the scan sequence, and"Delete" channel is not contained. In the scan mode, thiskey switches the channnel delete or add temporarily.• Talk aroundPress this key, the transceiver uses the receive fre-quency and the tone for transmission.The operator can call the other party directory (withoutrepeater). Press this key again, the talk around functiongoes off.• Volume up/downWhen the key is pressed, the volume level is increased/decreased and repeats if held for 200ms or longer.• NoneSounds error operation beep, and no action will occur.Use this function when the transceiver is required to bemore simple operated.4. Scan Operating (TK-860G only) Scan types• Single group scanYou can scan all valid (ADD) channels in the displayedgroup that can be selected with the group up/down key.• Multiple group scanYou can scan all valid (ADD) channels in the all valid(ADD) group.
