Basic Scan
The VXA-700 allows you to scan automatically in the
VFO*
1
, Main Memory, “Book” Memory, or Weather Chan-
nel*
modes. It pauses on signals encountered, so you can
talk to the station(s) on that frequency, if you like.
*
1: In the VFO mode, the automatic scanner is only avail-
able in the current operating band (AIR band, 2-m
Amateur band, or FM BC band). Furthermore, on the
AIR band, the automatic scanner is only available in
the COM band (118.000 - 136.975 MHz); when the
scanner reaches the uppermost frequency in the COM
band, it will revert to the bottom end of the COM band
and repeat the scanning process until you cancel the
scanning process.
*
2: USA version only.
If you wish to scan in the NAV band (108.000 - 117.975
MHz), you can do so manually, as described below.
Scanning operation is basically the same in each of the
above modes.
r Press the 
 key momentarily to start the automatic
scanner upward (toward a higher frequency or a higher
channel number).
r When the scanner encounters a signal, scanning pauses
and the radio remains on that channel until one sec-
ond after the signal disappears, after which scanning
will resume.
r While the scanner remains paused on a frequency, the
decimal point of the frequency display blinks. The dis-
play will be illuminated unless the Scan Lamp Fea-
ture is turned off.
r To change the scan direction, turn the DIAL selector
knob one click in the opposite direction.
r To stop the automatic scanner, press the PTT switch
or the 
 key momentarily..
The VXA-700’s automatic scanner is not operational in
the NAV band (108.000 - 117.975 MHz), because the NAV
stations (ILS, etc.) transmit constantly (thereby causing
the scanner to stop repeatedly). However, you can scan
manually in the NAV band, per the following procedure:
r Press and hold the 
 key to start the manual scan-
ner. Scanning will continue as long as the key is de-
pressed.
r Release the 
 key to stop the manual scanner im-
mediately.
Note: When scanning upward in frequency, when the fre-
quency reaches the COM Band (118.000 - 136.975 MHz)
via manual scanning, the VXA-700 will switch to the au-
tomatic scanner mode.
