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-120/170 receives the CTCSS tone pair which is stored in
the Receiving Pager Code Memory (configured via Set Mode Item 31: PAG.CDR) on the
frequency which is stored in Memory Channel "000," the radio will automatically transmit a
short (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. Furthermore, if your call sign is stored in the radio by Set Mode Item
11: CW WRI, the radio will transmit your callsign on the air when this feature is first engaged
by the remote page, and every 10 minutes thereafter.
In the Continuous mode, when the VX-120/170 receives the CTCSS tone pair which is stored
in the Receiving Pager Code Memory (configured via Set Mode Item 31: PAG.CDR) on the
frequency which is stored in Memory Channel "000," the radio will automatically transmit
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 by Set Mode Item 11: CW WRI, transmit your callsign on the air
at the activating this feature, and after that every 10 minutes thereafter.
The "callsign" ID can be changed to any desired sequence of characters, such as a name.
After sending the callsign or name, the radio will repeatedly transmit three tones for a
user-defined period of time (between 1 and 30 minutes). The callsign or name will be
transmitted every 10 minutes.
The Emergency Automatic ID (EAI) feature requires that you (1) store the CTCSS Tone Pair
into the Receiving Pager Memory (see page 44 for procedure), and (2) store the desired UHF
coordination frequency into Memory Channel "000" (see page 28 for procedure).

and its transmit time (1-10, 15, 20, 30, 40, and 50 minutes) or OFF.
5.
Press the PTT switch to save the new setting and exit to normal operation.
