4. Adjust the Doppler audio for the desired listening level.
Depress the AUDIO switch. The TARGET window
will display "Aud" and the PATROL window will
display the current audio level.
With "Aud" still being displayed, depress either the
AUDIO (down) or RANGE (up) switches to decrease or
increase the audio level. The displays will return to their
normal mode two seconds from the last switch entry or
momentarily depress the HOLD switch to return to
normal operation immediately.
5. To unsquelch the audio, depress the AUDIO switch. The
TARGET window will display "Aud". Depress the
PAT-SET switch. The LOCK/E.T. window will display
"Un".
To return to squelched audio, with "Aud" and "Un"
being displayed, again depress the PAT-SET switch.
The LOCK/E.T. window will be blank and the audio
will be squelched. Two seconds after the last switch
entry, the displays will return to their normal functions
or momentarily depress the HOLD switch to return to
normal operation immediately.
6. Set the range control to the desired level. Depress the
RANGE switch and the TARGET window will display
"rnG" and the PATROL window will display the current
level (1 - 6). Range level 6 is maximum range; range
level 1 reduces the Directional Golden Eagle II's range
to its minimum distance, typically 250 feet.
Depressing the DOWN (AUDIO) or UP (RANGE)
switches will decrease or increase the range level. The
displays will return to their normal mode after
approximately two seconds from the last switch entry or
momentarily depress the HOLD switch to return to
normal operation immediately.
