PERATION
Before activating the scanner, make sure that the Squelch is set to silence the background
noise when no signal is present. Scanning is not possible while the Squelch is open (if noise
or signals are being heard).
Scanning may be started or stopped using the microphone’s [UP] or [DWN] button. The
following techniques are used for scanning:
r Pressing and holding in either the [UP] or [DWN] button for one second in the VFO
mode will cause upward or downward band scanning, respectively, to begin.
r Pressing and holding in either the [UP] or [DWN] button for one second in the Memory
mode will cause memory channel scanning toward a higher- or lower-numbered memory
channel, respectively.
r Scanning pauses when a signal opens the squelch, and the decimal point on the display
will blink. You can choose one of three scan-resume modes (described later).
r To halt the scan manually, the easiest way is to push the PTT switch on the microphone
momentarily (no transmission will occur while you are scanning). The scan may also be
halted manually by pressing the microphone’s [UP] or [DWN] button, or the [D/
MR(MW)] key.

PTIONS
Three scan-resume modes are available on the FT-2800M:
r In the “BUSY” mode, the scanner will remain halted for as long as there is carrier present
on the channel; after the carrier drops at the end of the other station’s transmission,
scanning will resume.
r In the “HOLD” mode, the scanner will halt on a signal it encounters. It will not restart
automatically; you must manually re-initiate scanning if you wish to resume.
r In the “5 SEC” mode, the scanner will halt for five seconds only, after which scanning
will resume (whether or not the other station is still transmitting).
The default scan-stop mode is “BUSY.” To change the scan-resume mode, use the following
procedure:
1. Press and hold in the [MHz(SET)] key for one second, then rotate the DIAL knob to
select “23 SCAN.”
2. Press the [MHz(SET)] key, then rotate the DIAL knob to select the desired scan-resume
mode (BUSY/HOLD/5 SEC).
3. Press and hold in the [MHz(SET)] key for one second to save the new setting and exit to
normal operation.
