[. . . ] Rotate the DIAL knob to set this Set Mode Item to "RVT. ON. " 5. When you have made your selection, press the PTT switch to save the setting and exit to normal operation. To disable the Priority Revert operation, just repeat the above procedure, rotating the DIAL knob to select "RVT. OFF" in step 4 above. VX-177 OPERATING MANUAL 43 SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The VX-177 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-177 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-177 OPERATING MANUAL NOTE VX-177 OPERATING MANUAL 45 EMERGENCY FEATURE EMERGENCY CHANNEL OPERATION The VX-177 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 [4(RPT)] 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-177 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. The callsign of the incapacitated person will also be transmitted, to assist the rescue team. If an emergency group is working in a dangerous area, all members should engage the EAI feature on their transceiver, so that others can provide assistance to a fallen team member, if necessary. The Emergency Automatic ID (EAI) Feature has two operating modes: (1) Interval mode and (2) Continuous mode. In the Interval mode, when the VX-177 receives the CTCSS tone pair which is stored in the Receiving Pager Code Memory (configured via Set Mode Item 18: ECS. CDR) on the frequency which is stored in Memory Channel "200" for more than five seconds, the radio will automatically transmit a brief (0. 5 second) beep tone every 2. 5 seconds until the EAI timer expiration at the power level stored in that memory channel; it is NOT necessary for the incapacitated person to press the PTT switch. In the Continuous mode, when the VX-177 receives the CTCSS tone pair which is stored in the Receiving Pager Code Memory (configured via Set Mode Item 18: ECS. CDR) on the frequency which is stored in Memory Channel "200" for more than five seconds, the radio will automatically transmit (with maximum microphone gain) continuously, until the EAI timer expiration, at the power level stored in that memory channel; it is NOT necessary for the incapacitated person to press the PTT switch. Furthermore, if your call sign is stored in the radio via Set Mode Item 11: CW WRT and you have enabled the CW identifier by Set Mode Item 10: CWID, the radio will transmit your callsign on the air when the EAI feature is first engaged by the remote page, and every 10 minutes thereater.
