Monitor Function
You can select either QT/DQT or 5-tone decoding to be
canceled when [Monitor] or [Monitor momentary] key is
pressed. When monitor function is activated, "MON" icon
appears.
When the transceiver is set up in "QT/DQT", cancels the
decoding in QT/DQT decode. The squelch is controlled by
the signal carrier only.
When the transceiver is set up in "5-tone", cancels the
decoding 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 the
squelch.
Digit Entry Method
Receive, Selcall or Status digit appears when you enter
their 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 digit
number when entering their entry mode appears.
When the transceiver is set up in "Overwrite", new their
digit number will overwrite the previous their digit when en-
tering their entry mode.
When the transceiver is set up in "Replace", new their
digit number will overwrite the their digit that is pro-
grammed in RX address or TX address menu when entering
their entry mode.
Busy Channel Lockout
You can inhibit the transmission while the channel is
busy. You can program the following different conditions.
When the transceiver is set up in "Lockout 1"; Do not
transmit 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 not
transmit when the transceiver is receiving the carrier and
QT/DQT code does not match. Transmit when the trans-
ceiver is not receiving the carrier or receiving the QT/DQT
code matches.
Selectable Receive Digit
Select the check box to change receive code (maximum
8 digits) manually when receiving decode code. You cannot
select selectable receive digit, store selcall digit and store
status 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 the
receive code, #01. You can receive the receive code after
the modification.
