only apply
to 900
MHz
Analog Plus
stations
with
the
Spectra-TAC/DIGITAC
Encoder Option
(C269)
or an antenna relay.
For Analog Plus
stations
equipped
with
a
Spectra-TAC/DIGITAC
Encoder
Option
(C269) or
an antenna relay,
select
EEPOT
1
to
enable the Flutter
Fighter.
Verify
the
AC
voltage
at
TP1, on the
SSCB
is
35050
mVac
as
shown in
Figure
4-23.
If not, adjust
EEPOT
1.
Dekey
the station,
deactivate any activated
MUXbus
bits, connect any
disconnected cables, and remove any jumper wires that were installed.
Receiver Wireline Audio Adjustment
The following procedure adjusts
the
receiver wireline audio level for Line
2
and
Line
4.
The desired audio level is dependent upon the system configuration. If the
station is configured for Spectra-TAC/DIGITAC
Encoder Option
(C269). Proceed
directly
to the
High/Low
End Adjustment
to
compensate for line loss.
NOTE
4-42
Perform this procedure only
if
the station is
NOT
equipped
with
a
Spectra-TAC/DIGITAC
Encoder Option
(C269) to be
used in
a
voting system.
If voting
will
be
used, proceed
to the
High/Low
End Adjustment.
Inject
a
lmV
RF
receive signal, modulated
with
a
1
kHz
tone at 60%
full
station deviation into the receiver antenna connector on the Junction Box.
Refer
to
Table
4-8.
1.
Set the
PL Dis/Xmit
switch
to
PL Dis.
2.
Verify
the
receive audio between Line
2
(+)
and
Line
2
(-) on the Junction
Box screw terminal strip is at the desired phone line level.
3.
The typical phone line level
is from
0
dBm
to -10 dBm.
If not,
set
it by adjusting
EEPOT
