1. Recall the Memory Channel “EAI EAI EAI EAI EAI ” (must be the same as the
searched person’s radio), which is found in the next to the
last “regular” memory channel.
2. Set the CTCSS tone pair to the same CTCSS tone pair stored
in the Receiving Pager Code Memory of the missing person’s radio.

3. Press and hold in the PTT switch for five seconds. If the EAI signal is received by a
VX-8R transceiver programmed with matching EAI CTCSS tones the EAI feature
will activate. The lost operator’s radio will beep loudly, and its transmitter will re-
spond repeatedly. You may now begin direction-finding efforts.
4. The ATT (Front End Attenuator) is often useful in locating
the missing person’s radio, as peaks in weaker signals are
more easily observed. You may select the ATT level “ATT 1
