Table 13-4. Troubleshooting for Basic Repeater Controller (Cont'd.)
Symptom
11. Undesirable long squelch tails or
noise transmitted during drop-
out delay.
12. Audio OK in repeater operation
(between field radios) but noisy
when using local microphone on
a repeater radio.
13. Long delay in audio from micro-
phone plugged into transmit ra-
dio.
Table 13-5.
Symptom
1. Part or all of the reverse conver-
sation not repeated.
2. Transmitter of receive radio not
keying.
March, 2001
Problem
11a. Audio gate enabled with flat re-
ceive audio selected, S2-7 ON.
11b. Field radio reverse burst not
compatible with receive radio
TPL decoder.
12. "Flat" audio has been selected.
13. S2-5 and S2-6 simultaneously
ON.
Troubleshooting for Basic Repeater Controller Bi-Directional Repeater
Problem
1a. 0-second drop-out delay not
selected.
1b. User speaking too soon after
pressing PTT.
1c. Receive radio programmed as
"Rx Only Personality"
1d. Transmit radio programmed as
"Tx Only Personality".
1e. Receive radio is operating in an-
other repeater system and is
keeping transmit radio keyed
during drop-out delay.
2a. S2-1 not ON.
2b. Accessory connector of transmit
radio not programmed correctly
or not operating correctly.
2c. No transmit frequency pro-
grammed into receive radio.
2d. Receive radio programmed as
"Rx Only Personality"
2e. Transmit radio programmed as
"Tx Only Personality".
2f. Pin 3 of accessory connector of
receive radio not programmed
correctly.
2g. Loose or bad repeater cable(s).

Troubleshooting
Solution
11a. Set S2-7 OFF.
11b. Reprogram receive radio per-
sonality for "And Unmuting, Or
Muting" (under "Options").
12. Reprogram for "Rx Audio Type"
as "Filtered" audio on repeater
radios.
If flat audio is required, set S2-7
to OFF.
13. Set S2-5 (flat audio) ON and S2-6
(EIA audio) OFF, or set S2-6 ON
and S2-5 OFF.
Solution
1a. Set S2-11 ON.
1b. Delay conversation to allow for
delays in repeater and field radi-
os from:
• TPL/DPL decoding.
• Requirements of signalling
systems.
1c. Reprogram receive radio:
• Uncheck "Rx Only Personal-
ity".
• Add transmit frequency.
1d. Reprogram transmit radio:
• Uncheck "Tx Only Personal-
ity".
• Add receive frequency.
1e. Try using VOX circuit in control-
ler instead of COR detect. Works
best with strong signals.
2a. Set S2-1 ON.
2b. Check programming of accesso-
ry connector and reprogram, if
necessary.
2c. Program transmit frequency.
2d. Reprogram receive radio:
• Uncheck "Rx Only Personal-
ity".
• Add transmit frequency.
2e. Reprogram transmit radio:
• Uncheck "Tx Only Personal-
ity".
• Add receive frequency.
2f. Reprogram pin 3 of receive radio
for "External Mic PTT", active
level "Low".
2g. Check repeater cable connec-
tion(s) and replace cable(s), if
necessary.
