Repeater Mode
Deviation Adjustment

First ensure that the "DUPLEX" mode of operation
is enabled via CE27 Channel/Alignment Program.
 Set the BASE/REPEATER switch on the front panel
of the repeater to the "REPEATER" mode (the RE-
PEATER LED will turn on).
 Inject a signal on the Center channel frequency at a
level of 40 dBμ (1 kHz tone @ ±3 kHz deviation)
from the RF Signal Generator into the RX antenna
jack, and adjust VR4001 (on the CNTL Unit) so that
the deviation meter reading (TX deviation) is ±3.0
kHz (±0.1 kHz) deviation.

Base Mode
Alignment Setup
 Set the BASE switch on the front panel of the re-
peater to the "BASE" mode (the REPEATER LED
will turn off).
 Press the LOCAL/REMOTE switch on the front pan-
el of the repeater to the "REMOTE" mode (the RE-
MOTE LED will turn on).
 Set S4001 and S4002 on the CNTL Unit to the "0
(off)" position and "1 (on)" position respectively, then
select the Center channel.
Audio Level Adjustment (LINE OUT Level)
 Inject a signal on the Center channel frequency at a
level of -73 dBm (1 kHz tone @ ±3.0 kHz deviation)
from the RF Signal Generator into the RX antenna
jack, and adjust VR4002 (on the CNTL Unit) so that
the "Line Out" audio level (LINE jack pins 5 and 6)
is –10 dBm (±0.1 dBm).
Deviation Adjustment (LINE IN Level)
 Connect the AF generator to LINE jack pins 3 and 4,
and the AF generator output level to -10 dBm, at a
frequency of 1 kHz.
 Key the repeater, and adjust VR4003 (on the CNTL
Unit) so that the deviation meter reading (TX devia-
tion) is 3.0 kHz (±0.1 kHz) deviation.
