Decoded Receive Audio Adjustment
The following procedure
adjusts
the
decoded receive audio level
for stations
containing
the
Secure
Encryption Option (C331, C388, C794, C795,
or
C797). Before
performing this procedure, make sure the
level of Line
2
is adjusted to the same
relative level
(0
dB)
as the
clear receive audio level.
NOTE
The Line
2
level must
be adjusted before
performing
this procedure.
1.
Inject
a
mV
RF
receive signal, modulated
with
a
secure
(digitally
encrypted) 1
kHz
tone at
3.9
kHz
deviation into the receiver antenna
connector on the
Junction
Box.
NOTE
The encryption source must be
programmed
with
the
same
encryption key
as the
station. Refer to
Chapter
2
-
Operation for additional information.
2.
Verify
the
outbound receiver audio between
Line
2
(+)
and
Line
2
(-) is
0
dB
relative
to the clear
wireline audio level.
The
clear
wireline audio level setting was
set
up in the
Receive Wireline
Audio
Adjustment procedure
or the
maximum allowable phone line level,
whichever
is less.
If
not, adjust
EEPOT
0.
