VX-170 OPERATING MANUAL 43 SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The VX-170 will automatically illuminate the LCD/Keypad Lamp whenever the scanner stops on a signal; this allows you to see the frequency of the incoming signal better at night.

Press the [F] key momentarily to enable adjustment of this Set Mode Item. When you have made your selection, press the PTT switch to save the setting and exit to normal operation. BAND EDGE BEEPER The VX-170 will automatically "beep" when a band edge is encountered during scanning (either in standard VFO scanning or during PMS operation). You may also enable this feature (band edge beeper) to operate when the frequency reaches the band edge while tuning using the DIAL knob. Press the [F] key momentarily to enable adjustment of this Set Mode Item. When you have made your selection, press the PTT switch to save the setting and exit to normal operation. 44 VX-170 OPERATING MANUAL SCANNING WEATHER ALERT SCAN This feature allows you to check the Weather Broadcast Memory Channels for the presence of the NOAA Alert Tone while operating using VFO scan or Memory channel scan. When the Weather Alert Scan feature is engaged, the VX-170 will check the Weather Broadcast Memory Channels for activity every five seconds while scanning. If you watch the display carefully, you'll observe the scanner periodically shifting to the Weather Broadcast bank, scanning the Weather channels quickly in search of the Alert Tone, after which regular scanning will resume for another five seconds.
