14TK-780 Monitor FunctionYou can select either QT/DQT or 5-tone decoding to becanceled when [Monitor] or [Monitor momentary] key ispressed. When monitor function is activated, “MON” iconappears.When the transceiver is set up in “QT/DQT”, cancels thedecoding in QT/DQT decode. The squelch is controlled bythe signal carrier only.When the transceiver is set up in “5-tone”, cancels thedecoding in 5-tone decode. The squelch is controlled by QT/DQT decode only.If QT/DQT code is programmed in QT/DQT decode, in-coming signal must match the QT/DQT code to open thesquelch. Digit Entry MethodReceive, Selcall or Status digit appears when you entertheir entry mode, pressing [Receive entry], [Selcall entry] or[Status entry] key, or “Keypad operation” is programmed to“Selcall entry” or “Status entry” and press [0] to [9] key.You can select the operation of the function. Or the digitnumber when entering their entry mode appears.When the transceiver is set up in “Overwrite”, new theirdigit number will overwrite the previous their digit when en-tering their entry mode.When the transceiver is set up in “Replace”, new theirdigit number will overwrite the their digit that is pro-grammed in RX address or TX address menu when enteringtheir entry mode. Busy Channel LockoutYou can inhibit the transmission while the channel isbusy. You can program the following different conditions.When the transceiver is set up in “Lockout 1”; Do nottransmit when the transceiver is receiving the carrier.Transmit when the transceiver is not receiving the carrier.When the transceiver is set up in “Lockout 2”; Do nottransmit when the transceiver is receiving the carrier andQT/DQT code does not match. Transmit when the trans-ceiver is not receiving the carrier or receiving the QT/DQTcode matches. Selectable Receive DigitSelect the check box to change receive code (maximum8 digits) manually when receiving decode code. You cannotselect selectable receive digit, store selcall digit and storestatus digit at the same time.For example, the transceiver receives 5-tone code,#59401 when you have 4th and 5th digit checked in select-able receive digit menu. In this case, #01 is stored as re-ceive code.Press [Receive entry] key to enter receive entry mode.When you enter receive entry mode, you can change thereceive code, #01. You can receive the receive code afterthe modification. Selectable Selcall DigitSelect the check box to change selcall code (maximum 8digits) manually when transmitting encode code. You can-not select selectable selcall digit and selectable status digitat the same time.For example, the transceiver receives 5-tone code,#59401 when you have 4th and 5th digit checked in select-able selcall digit menu. In this case, #01 is stored as selcall.Press [Selcall entry] key or “Keypad operation” to enterselcall entry mode. When you enter selcall entry mode, youcan change the selcall code, #01. You can transmit theselcall after the modification. Selectable Status DigitSelect the check box to change status code (maximum 8digits) manually when transmitting encode code. You can-not select selectable selcall digit and selectable status digitat the same time.For example, the transceiver receives 5-tone code,#5940167 when you have 6th and 7th digit checked in se-lectable status digit menu.Press [Selcall entry] key or “Keypad operation” to enterstatus entry mode. When you enter status entry mode, youcan change the status code, #67. You can transmit the sta-tus code after the modification. Automatic CloseIt compares the selected digits of RX address code inchannel menu when the transceiver receives 5-tone signal-ling. If the selected digits matches to the received 5-tonecode, the transceiver closes monitor. You can select maxi-mum 8 digits of RX address. Copy from TX/RX addressYou can select to copy the digit to the memory when youchange the channel, using [Channel up], [Channel down]key. The memory represents the code that is displayed bythe keypad. Or key buffer, “^K1 ... ^K8” used by encodeformat.Receive digit in “RX address” is copied when the chan-nel is changed. Selcall/Status digit in “TX address” is copiedwhen the channel is changed. Encode CodeWhen “Special setting” is disabled, you can select theencode code to transmit when [Call 1 to 6] key is pressed.You can select up to 3 codes to transmit 3-frame 5-tonecode. The encode code is transmitted from left to rightdigit. 24 different encode codes are available.When “Special setting” is enabled, you can select theencode format setting from #1 to #32. You can select theencode format name, configured in encode format menu.OPERATING FEATURES
