NOTE
These recommended levels are intended for co-located.
consoles
which do not have phone line loss. If
other
levels
are
required due to phone line loss, the same
relative relationship of signal levels should be
maintained.
CAUTION
Do not key the station
via RSS
or
by setting
the
PTT
MUxXbus
bit since these methods do no set
ALC
correctly.
2.
Inject an
HLGT/FT
sequence
followed by
a
1
kHz
tone
with
LLGT
across
the appropriate transmit wireline terminals, using
a
console or service
monitor.
Line
1
+/-
for
four-wire systems
or
Line
2
+/-
for
two-wire
systems.
Set and hold the
PL Dis/Xmit
switch
to
Xmit
during
step
4.
3.
This strips any data from being summed
with
the
transmit audio.
Adjust
transmit audio level
via
EEPOT
7
until
the
transmitted deviation
level
reaches 60%
full
system deviation,
as
indicated in Table
4-8.
Refer
to
Chapter
2
-
Operation for additional information relating to the
EEPOT
adjust mode.
Remove
the
LLGT
and
1
kHz
test tone.

5.
Inject
a
1
kHz
tone at the
average audio phone line level (i.e.,
66
dB below
peak audio) through
the
wireline into
the
Line
3
input
on the system
connector of the
Junction
Box.
6.
If this is
a
trunked station,
disconnect the
trunking
cable from
Junction
Box
connector (J3).
7.
Key
the transmitter
by connecting
a
jumper wire jumper from J2901-8
(TKG PTT) to J2901-1 (LOGIC GND)
on the
TTRC
logic
board.
Set and hold the
PL Dis/Xmit
switch
to
Xmit during
step
11.
This
strips any data from being summed
with the transmit audio.
9.
Scroll completely through
the
EEPOT numbers once, and then back to
EEPOT
