Vertex Standard VX-177 manual Scanning, Setting the Scan-Resume Technique

SCANNING

The VX-177allows you to scan just the memory channels, the entire operating band, or a portion of that band. It will halt on signals encountered, so you can talk to the station(s) on that frequency, if you like.

Scanning operation is basically the same in each of the above modes. Before you begin, take a moment to select the way in which you would like the scanner to resume scanning after it halts on a signal.

Setting the Scan-Resume Technique

Three options for the Scan-Resume mode are available:

BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the carrier has dropped because the other station(s) ceased transmission, the scanner will resume. In the case of constant-carrier signals like Weather Station broad- casts, the scanner will likely remain on this frequency indefinitely.

HOLD: In this 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.

TIME: In this mode, the scanner will halt on a signal it encounters, and will hold there for five seconds. If you do not take action to disable the scanner within that time period, the scanner will resume even if the stations are still active.

To set the Scan-Resume mode:

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 32: RESUME.

3. Press the [F] key momentarily to enable adjustment of this Set Mode Item.

4. Rotate the DIAL knob to select the desired scan-resume mode.

5. When you have made your selection, press the PTT switch to save the new setting and exit to normal operation.

The default condition for this Set Mode Item is “BUSY.”

SETTING THE SQUELCH LEVEL DURING ACTIVE SCANNING OPERATION

The VX-177allows adjustment of the Squelch level “on the fly” while you are scanning. 1. While the scanner is engaged, press the [F] key, then press

the MONI switch (the current squelch level (e.g. “S 3”) will appear in fine print above the frequency display).

2.Rotate the DIAL to select the desired Squelch level.

3.Press the PTT switch momentarily to save the new setting and exit to normal operation. In this case, pressing the PTT switch this one time will not causing scanning to stop.
