Version: 1.01 Field Programming Reference (FPRG) 286 EDIT MENU! The duration configured in the Repeat Hold Time is handledas the TOT.! The audio signal is muted while the Repeat Hold Time iscounting down." DQT Turn-off CodeIt can configure a duration to send a DQT Turn-offcode. This function eliminates the squelch tail noiseon the receiving side by sending the DQT Turn-offcode when the transmitting party stop to transmit.You can configure it by the spin buttons or directlyenter the value.Note: When the QT/DQT Encode configured to the channel isDQT, the DQT Turn-off code is sent." QT Decode DelayIt can configure a duration between the time when thetime the received QT signalling un-matches and thetime when the TKR-750/850/751/851 starts the QTDecode operation. With this function, the QT ReverseBurst code should not be recognized as a normal QTsignalling. You can configure a time by the spinbuttons or directly enter the value. (Refer to 6.2.12 QTReverse Burst.)Note: The TKR-750/850/751/851 starts the QT Decodeoperation immediately after the received QT signallingun-matches if the QT Decode Delay is disabled." Test ToneIt can configure the frequency of single tonetransmitted when Test Tone assigned to a PF key oran Auxiliary Input Port is enabled. You can configurea tone by the spin buttons or directly enter the value toconfigure the duration. (Refer to 6.5 Key AssignmentWindow, 6.10 Function Port Window.)Note: The TKR-750/850/751/851 sends the CW ID/Messageonly when sending the CW ID/Message whiletransmitting Test Tone. It does not modulate the repeataudio signal while transmitting Test Tone. (Refer to 6.3CW ID Window, 6.12 CW Message Window.)" Squelch LevelIt can configure a squelch level used to eliminate theweak signal. It should decrease to listen to weak radiosignals and increase the level for only strong radiosignals communication. You can configure the level bythe spin buttons or directly enter the value.Note: When using the channel that “Operation Mode” isconfigured as “Repeat” and the “QT/DQT Encode” isconfigured as “None”, the TKR-750/850/751/851activates the repeat operation regardless of thepresence of the reception signal if the Squelch Level isconfigured as “0”. (Refer to 6.2.4 QT/DQT Encode, 6.2.8Operation Mode.)" QT Reverse Burst TimeIt can configure a duration to send the QT ReverseBurst code. This function eliminates the squelch tailnoise on the receiving side by sending the QTReverse Burst code at end of transmitting. You canconfigure a duration by the spin buttons or directlyenter the value. (Refer to 6.2.12 QT Reverse Burst.)Note:! This function is available only when the QT/DQT Decodecode is enabled in the “Channel Edit” window.! When the QT/DQT Encode code configured to the channelis QT, the TKR-750/850/751/851 sends the QT ReverseBurst Code. When the DQT Encode is selected, the it sendsthe QT Turn-off Code." Backup Battery SystemIt can configure a timing to emit the Backup BatteryWarning Tone/Operation Tone. Select “SecondaryInput Backup” or “Main Line Backup” from thedropdown list. (Refer to 6.4.2 Optional Features 2Tab.)" Power Supply Lower LevelIt can configure a reference voltage in order toactivate/deactivate the Power Supply Lower Limit.This function activates an Auxiliary output port that isassigned to the Power Supply Lower Limit when theRange 140 - 200 msIn steps of 1 msDefault 170 msRange Off, 1 - 250 msIn steps of 1 msDefault 80 msRange 300 - 3000 HzIn steps of 1 HzDefault 1000 HzRange 0 (Shallow) - 15 (Tight)In steps of 1Default 1Range 140 - 200 msIn steps of 1 msDefault 160 msRangeSecondaryInputBackupEmits the Backup Battery WarningTone or the Operation Tone when thepower is switched from the mainpower to the backup power.Main LineBackupEmits the Backup Battery WarningTone or the Operation Tone when thevoltage of the main power becomeslower than the Power Supply LowerLevel.Default Secondary Input Backup
