SCANNING

The FT-2800M’s scanning capability provides the operator with many convenient methods of rapid frequency navigation.

BASIC SCANNER OPERATION

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:

rPressing 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.

rPressing 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.

rScanning 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).

rTo 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.

SCAN-RESUME OPTIONS

Three scan-resume modes are available on the FT-2800M:

rIn 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.

rIn 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.

rIn 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.
