Press the [VFO(PRI)] key to disable the VFO-VFO Dual Watch. Priority Revert Mode During Priority channel operation (Dual Watch), a special feature is available which will allow you to move to the Priority channel instantly, without waiting for activity to appear on the Priority channel.

VX-127 OPERATING MANUAL 43 SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The VX-127 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. Note that this will, of course, increase the battery consumption, so be sure to switch it off during the day (the default condition for this feature is "ON"). 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-127 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-127 OPERATING MANUAL NOTE VX-127 OPERATING MANUAL 45 EMERGENCY FEATURE EMERGENCY CHANNEL OPERATION The VX-127 includes an "Emergency" feature which may be useful if you have someone monitoring on the same frequency as your transceiver's "Home" channel. The "Emergency" feature is activated by pressing and holding in the [SET( )EMG] key for one second. When this is done, (A) the radio is placed on the Home channel, (B) it emits a loud "Alarm" sound (the volume is controlled by the VOL/PWR knob), (C) it flashes the LCD/keypad lamp, (D) if you press the PTT switch, you will disable the Emergency feature temporarily; you can then transmit on the Home channel, and (E) two seconds after the PTT switch release, the Emergency feature will resume. To disable the "Emergency" feature, press the [F] key momentarily or turn the radio off by rotating the VOL/PWR knob fully counter-clockwise into the click-stop position. Use this feature if you are out for a walk and want a quick way of alerting a family member as to a dangerous situation. 1) Be sure to arrange with a friend or family member to be monitoring on the same frequency, as there will be no identification sent via the Emergency alarm sound. 2) The "Emergency" feature may be changed to another function via Set Mode Item 21: EMG S; see page 76 for details. 46 VX-127 OPERATING MANUAL EMERGENCY FEATURE EMERGENCY AUTOMATIC ID (EAI) FEATURE The Emergency Automatic ID (EAI) feature can be used for searching for persons who are incapacitated in disasters like earthquakes, especially search-and-rescue personnel who may have become injured in a debris field. In such cases, if another searcher sends out a unique command (CTCSS tone pair), the radio of the incapacitated party, who may not be able to speak or even press the PTT switch, will automatically cause the injured party's radio to transmit, so others may perform direction-finding and effect a rescue.
