Emergency Channel Operation
The VX-120/170 includes an "Emergency" feature which may be useful if you have someone
monitoring on the same frequency as your transceiver's "Home" channel. See page ?? for
details on setting the 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 UHF amateur band Home channel,
(B) it emits a loud "Alarm" sound (the volume is controlled by the VOL knob), (C) it flashes the
LCD/keypad lamp, (D) if you press the PTT key, you will disable the Emergency feature
temporarily; you can then transmit on the Home channel, and (E) two seconds after the PTT
release, the Emergency feature will resume.
To disable the "Emergency" feature, press the [F/W] 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. The alarm sound may discourage an attacker and allow you to
escape.
R.F. Says: 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. And do not
transmit the alarm tone except in a true emergency!
2) The "Emergency" feature may be changed to another function via Set Mode Item 21: EMG
S; see page ?? for details.
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, 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
