2. Programmable keys
The functions the FPU programs to the function keys are
described in the following sections.
1) Channel up/down (TK-270G only)
When the key is pressed each time, the channel number to
be selected is incremented/decremented and repeats if held
for one second or longer.
This key functions as the voice scrambler code selector in
the voice scrambler code select mode.
2) Display character (TK-270G only)
This key switches the LCD display between the group/
channel number and group/channel name.
3) Group up/down (TK-270G only)
When the key is pressed each time, the group number to
be selected is incremented/decremented and repeats if held
for one second or longer.
4) Home Channel (TK-270G only)
Press this key once, the channel switches to the pre-
programmed home channel.
5) Key lock (TK-270G only)
When the KEY LOCK switch is held down for one second
or more, keys other than [PTT], [LAMP], [MONI], [VOL],
[POWER], and KEY LOCK are locked.
When 12/16 KEY LOCK is set with the FPU, the DTMF
key is locked and when front-panel KEY LOCK is set, the
DTMF key and the [PF] key are locked.
6) Lamp (TK-270G only)
This key illuminates the LCD and keys on the front panel.
When the key is pressed, the LED lamp goes on.
When it is released, the lamp goes off after about five
seconds. If any key is pressed while the LED lamp is on,
the lamp is kept on for five seconds.
7) Monitor
Used to release signalling or squelch when operating in
conventional mode. It is also used to reset option signalling.
8) Operator Selectable Tone (TK-270G K types only)
This key switches the pre-set decode QT/DQT and encode
QT/DQT to OST (Operator Selectable Tone) tone pair.
Press this key, the transceiver enters OST mode. In this
mode, the display shows "OFF" and the operator can select
one of the OST tone pair using the tuning control. The display
shows "TONE ∗∗" and tone pair No. ∗∗ is selected.
Press OST key again, the transceiver exits from OST mode,
and returns to the group/channel mode.
16 tone pairs for OST can be programmed by KPG-56D.
OST is useful to access the repeater with same radio
frequency and different tone (QT/DQT).
