Table 8-1 lists the programmable audio selections for
the Professional Series transmit and receive radios
when used with the Basic repeater controller. Table 8-2
lists the jumper settings for JU1 on the Basic repeater
controller.

Adjustments

The following steps should be performed with a ser-
vice monitor, such as the Motorola R2000 series, con-
nected to the antenna jack of the duplexer (or the
transmit radio, if applicable). The service monitor must
be operating in the duplex mode. Set the service moni-
tor to monitor the frequency of the transmit radio
while generating the duplex signal at the frequency of
the receive radio. Refer to the operating instructions of
your service monitor.
1. Remove the Basic repeater controller in its
tray from the repeater. Remove the controller
from its tray, then remove the controller board
from the housing by unscrewing the two long
T15 machine screws at the rear of the housing.
It will be necessary to unplug the cables from
the board.
2. Reattach the cables to the Basic repeater control-
ler board after the board is out of the housing.
3. Before energizing the power supply or the
radios, ensure that the REPEATER ENABLE
switch of the Basic repeater controller is in the
released (out) position. Failure to "disable"
the repeater will result in keying of the trans-
mit radio.
4. Connect the line cord from the power supply of
the repeater to a suitable 50/60 Hz ac source.
5. If necessary, turn on the two radios by push-
ing in the volume controls.
6. If the yellow LED is not illuminated, press the
SET-UP momentary pushbutton switch.

7. Press the REPEATER ENABLE switch to the
engaged (in) position; the green LED should
illuminate.
8. Modulate the duplex generator of the service
monitor with a 1 kHz tone at 60 percent of full
rated system deviation.
9. Adjust potentiometer R23 in the Basic
repeater controller for 60 percent of full rated
system deviation of the transmit radio. If you
cannot achieve at least 50 percent full rated
system deviation with R23 at the maximum
setting, increase the "Accessory Mic Gain
(dB)", under Radio Configurations in the CPS,
for the transmit radio and readjust R23.
10. For a bi-directional repeater, apply a signal at
the frequency of the receiver of the transmit
radio. Modulate the duplex generator of the
service monitor with a 1 kHz tone at 60 per-
cent of full rated system deviation.
11. Set the service monitor to monitor the fre-
quency of the transmitter of the receive radio.
12. Adjust potentiometer R24 in the Basic
repeater controller for 60 percent of full rated
system deviation of the receive radio. If you
cannot achieve at least 50 percent full rated
system deviation with R24 at the maximum
setting, increase the "Accessory Mic Gain
(dB)", under Radio Configurations in the CPS,
for the receive radio and readjust R24.
13. Check the settings of the 12 positions of DIP
switch S2 for correctness.
14. Unplug the cables attached to the Basic
repeater controller board.
15. Place the Basic repeater controller board into
the housing. Attach the front panel with the
two long T15 machine screws that were
removed in Step 1.
16. Attach the cables to the Basic repeater controller.
17. Follow the procedures in this manual to
remount the Basic repeater controller in its
tray in the repeater housing.
