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 devia-
tion meter reading (TX deviation) is ±3.0 kHz (±0.3
kHz) deviation.

 Inject a signal on the Center channel frequency at a
level of 40 dBμ (1 kHz tone @ ±3.5 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 (±0.5 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.
