2) Direct Keypad Frequency Entry

The desired operating frequency may be entered directly from the keypad. The first “1” in
the frequency does not need to be entered, as it is “assumed” by the microprocessor.

To enter a frequency directly, just key in the 10 MHz, 1 MHz, and the kHz digits.

Examples: To enter 436.560 MHz, press [3] 

 [6]  [5] [6] [0]

To enter 436.5625 MHz (12.5 kHz steps), [3] 

 [6]  [5] [6] [2]

3) Scanning

Press and hold in either the [

(MHz)] or [(MHz)] key

for one second to initiate upward or downward scanning,
respectively (Manual VFO Scan).

For scanning within a limited sub-band range, from the VFO
mode, press and hold in the [MR(SKIP)] key for one sec-
ond to begin scanning toward a higher frequency within the
previously-defined sub-band (Programmed VFO Scan). De-
tails regarding sub-band setup may be found on page 37.

If you wish to reverse the direction of the scan (i.e. toward a
lower frequency, instead of a higher frequency), just rotate
the DIAL one click in the counter-clockwise direction while
the VX-177 is scanning. The scanning direction will be re-
versed. To revert to scanning toward a higher frequency once
more, rotate the DIAL one click clockwise.

The scanner will stop when it receives a signal strong enough to break through the Squelch
threshold. The VX-177 will then hold on that frequency according to the setting of the
“RESUME” mode (Set Mode Item 32: 

RESUME

). Press the PTT switch momentarily to

cancel the scanning. This only stops the scan; it does not cause transmission to occur. See
page 36 for details regarding Scan Operation.
