The Emergency Automatic ID (EAI) feature can be used to aid in searching for persons
who are incapacitated in disasters like earthquakes, especially search-and-rescue person-
nel who may have become injured in a debris field. When using the EAI feature, a searcher
transmits a unique command (CTCSS tone pair), which will automatically cause the in-
jured party's radio to transmit, so others may perform direction-finding and effect a res-
cue. The incapacitated party may not be able to speak or even press the PTT switch. The
callsign of the incapacitated person may 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 transceivers, so that others can assist 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-8DR/DE receives the
CTCSS tone pair), the radio will transmit a loud (0.5 second) beep every 2.5 seconds until
the EAI timer expires. In the continuous mode, the radio will automatically transmit a
continuous signal (with maximum microphone gain), until the EAI timer expires.
The EIA is activated when the CTCSS tone pair stored in the Receiving Pager Code Memory
(configured via Set Mode Item 67: PAGE CODE-RX) is received for 5 seconds on the
frequency, which is stored in Memory Channel "EAI." It is NOT necessary for the inca-
pacitated person to press the PTT switch.
A call sign may be stored in the radio and the CW identifier enabled via Set Mode Item
21: CW. Then, when the EAI feature is activated in the Interval mode, the radio will
transmit the callsign once each minute. In addition, the bright LED will blink the call sign
in Morse code. The "callsign" ID can be changed to any desired sequence up to 16 char-
acters, such as a name. The radio will transmit a loud (0.5 second) beep every 2.5 seconds,
and send the call sign each minute, until the EAI timer expires.
The Emergency Automatic ID (EAI) Feature requires that you:
1) Store the CTCSS Tone Pair into the Receiving Pager Memory (see page 40 for the
procedure),
2) Store the desired UHF coordination frequency into Memory Channel "EAI" (see page
47 for procedure). (We suggest using a frequency different from your normal operat-
ing channel.)
3) Set the operating band to "A-Band".
4) Activate the EAI function "Set Mode Item 32: EAI" to "ON". The VX-8DR/DE radio
may now be used normally.
The EIA function will monitor the EIA memory channel in the background, and it will be
activated when the Pager Memory Tone Pair is received on the EIA memory channel.
