VX-8DR/DE OPERATING MANUAL110
TO LOCATE AN UNRESPONSIVE OPERATOR USING THE EAI FEATURE
1. Recall the Memory Channel “EAI” (must be the same as the
searched person’s radio), which is found at the end of the
“regular” memory channels.
2. Set the Transmitting Pager Code Memory tone pair to the
same CTCSS tone pair stored in the Receiving Pager Code Memory of the missing
person’s radio.
1) Press the key, then press the key. This pro-
vides a “Short-cut” to Set Mode Item 68: PAGE CODE-
TX.
2) Rotate the DIAL knob to select the first tone.
3) Press the key.
4) Rotate the DIAL knob to select the second tone.
5) Press the key to save the new setting and exit from
setting mode.
3. Press and hold in the PTT switch for five seconds. If the EAI signal is received by a
VX-8DR transceiver programmed with matching CTCSS Receiving Pager Code, the
EAI feature will activate. The lost operator’s radio will transmit in accordance with
the setting of Set Mode item 33: EAI TIME (For example, in the Interval mode, 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 continuously
with maximum microphone gain). You may now begin direction-finding efforts.
4. The ATT (Front End Attenuator) is often helpful in locating
the missing person’s radio, as peaks in weaker signals are
more easily observed. You may select the ATT level “ATT 1
(10 dB),” “ATT 2 (50 dB),” and “ATT OFF” by pressing the
key to reduce the signal.
5. Press the key to exit to normal operation.
