(1) BURST
When this switch is in the ON position, a short
duration audio tone of 1800 Hz will be super-
imposed on the transmitted signal. This is normally
used only with repeaters requiring tone access.
(2) BUSY/MAN/CLEAR
This switch selects the mode of the PLL scanner.
In the BUSY position, the scanner will search until
it finds an occupied channel (one containing a
signal strong enough to trip the FT-227R13
squelch). In the MAN position, scanner stop
commands come exclusively from the microphone.
In the CLEAR position, the scanner will search
until it finds a channel which has no signal present.
