Werecommend to set these mode to Disable after set up tosave contents.3-15. IDThe transceiver is capable to have ID. The format isDTMF. The timing that the transceiver sends ID is program-mable.Connect ID : Connect ID is send on beginning of trans-mission.Disconnect ID : Disconnect ID is send on end of trans-mission.Both : Connect ID is send on beginning of transmissionand disconnect ID is send on end of transmission.Off : Sending ID function is disabled.There is also "PTT ID" setting for each channel. Refer"PTT ID" of channel feature.3-16. OST (Operator Selectable Tone)The transceiver is capable to have "OST" function and16 tone pair (QT/DQT) with max 7-digit name for each tonepair.• "OST" Back UpThe transceiver is programmable the selected "OST"code is memorized or not. If you set to Disable (no memo-rized), the "OST" function always starts at "off".• Direct "OST"It is possible to call "OST" number directory using keypad.In this case, keypad is used for "OST", then "DTMF Auto PTT""DTMF Auto Dial" functions by keypad are not usable.3-17. Radio Password (Keypad Model Only)The radio password prevent unauthorized users opera-tion. Every time the power on, transceiver is locked andunusable until entering correct password.Enter pre-programmed password by FPU and [#] keycauses the transceiver unlocked.3-18. Data Password (Keypad Model Only)The data password prevents unauthorized reading of theprogrammed transceiver data by FPU. Enter pre-pro-grammed password in FPU reading process. This passwordalso protects the clone.Enter pre-programmed password by FPU and [#] key toclone.4. Group FeaturesYou can use these features using the programming soft-ware (KPG-38D).4-1. "TOT" (Time-Out Timer)The transceiver has the "TOT". This parameter selectsthe period of time users can continuously transmit.When the selected period passes, the transceiver gener-ates an warning tone and stops the transmission.4-2. "TOT" Pre-AlertThe transceiver has "TOT" pre-alert timer. This parameterselects the time at which the transceiver generates "TOT"pre-alert tone before "TOT" is expired."TOT" will be expired when the selected time passesfrom a TOT pre-alert tone.4-3. "TOT" Re-Key TimeThe transceiver has "TOT" re-key timer. This timer is thetime you can not transmit after "TOT" exceeded. After "TOT"re-key time expired you can transmit again.4-4. "TOT" Reset TimeThe transceiver has "TOT" reset timer. This timer is theminimum wait time allowed during a transmission that willreset the "TOT" count."TOT" reset time causes the "TOT" to continue even afterPTT is released unless the "TOT" reset timer has expired.4-5. Group Delete/AddThe transceiver can set the delete/add in each group. If"Delete" is selected, the transceiver does not scan the de-leted group in multi group scan.4-6. Battery SaveThis is the automatic battery saver during a standbymode operation. The receiver circuit is repeated on and offto conserve the battery life.4-7. SignallingSignalling "AND/OR" sets the audio unmute condition forany channel programmed with the option signalling (2-Tone/DTMF).AND : "AND" requires both the valid option signalling andthe programmed QT/DQT to be received for audio tounmute (and initiate an option signalling decode alert).OR : "OR" requires either the valid option signalling or theprogrammed QT/DQT to be received for audio to unmute(an option signalling decode alert is only initiated if theproper option signalling is decoded).OPERATING FEATURES
