Troubleshooting CDR500 & CDR700 Repeater Service Manual
3. ZR310 does not detect TPL/DPL
signals (functions properly in
CSQ mode). 3. Receive radio programmed for
“Filtered” accessory connector
receiver audio. 3. Reprogram “Rx Audio Type” as
“Flat Audio”.
4. No or intermittent decode of
proper TPL/DPL codes by field
radios. 4a. Improper TPL/DPL level to
transmit radio.
4b. Transmit radio programmed for
TPL/DPL (interferes with
ZR310 TPL/DPL).
4c. Incorrect position for JP3 in
ZR310.
4d. Loose or bad repeater cable from
ZR310 to transmit radio.
4a. Adjust “TPL/DPL” control on
ZR310.
4b. Reprogram transmit radio for
CSQ.
4c. Place in “A” position and adjust
“TPL/DPL” control on ZR310.
4d. Check repeater cable connec-
tion(s) and replace cable, if nec-
essary.
5. No decode of proper DPL codes
by ZR310; PL tones OK. 5. Inverted DPL sense from receive
radio. 5. Use DTMF programming to pro-
gram inverted receive DPL
sense in ZR310 (command 218#)
6. Transmit radio not keying when
a properly identified signal is
presented to receive radio. 6a. User group not enabled in
ZR310.
6b. Normal operation of ZR310
when channel is active.
6a. Enable user group by repro-
gramming.
6b. Wait until channel is inactive.
7. Transmit radio keying without a
properly identified signal pre-
sented to receive radio. 7a. Wrong user group programmed.
7b. CSQ (“OPEN”) user defined but
not desired.
7a. Reprogram ZR310.
7b. Reprogram ZR310.
8. Transmit radio keys but low or
no audio is transmitted. 8a. “AUDIO” potentiometer of
ZR310 not adjusted correctly.
8b. “Accessory Mic Gain” set too
low in transmit radio.
8c. “Ext PTT Audio” source for
transmit radio incorrect.
8a. Readjust “AUDIO” potentiome-
ter on front panel of ZR310
8b. Reprogram “Accessory Mic
Gain” of transmit radio.
8c. Reprogram “Ext PTT Audio” for
“Ext Mic & Flat Tx” audios.
9. No PL/DPL transmitted. 9a. No PL or DPL users defined in
ZR310 database.
9b. “Ext PTT Audio” source for
transmit radio incorrect.
9a. Program ZR310 database.
9b. Reprogram “Ext PTT Audio” for
“Ext Mic & Flat Tx” audio.
10. Low frequency (400 Hz) “beep”
heard just before transmit radio
unkeys.
10. Possible ZR310 memory check-
sum problem.
10. Use remote diagnostics to deter-
mine cause. Reprogram data-
base as required.
11. Memory automatically resets to
default settings.
11. Greater than 15 errors were de-
tected at resets or power-up.
11. Reprogram ZR310 database.
12. ZR310 fails to operate. No repeat
functions. Appears “locked up”.
12. ZR310 in “Never-Neverland”
due to transient.
12. Reset ZR310 by sending any
DTMF digit from a mobile or
portable radio for more than 15
seconds.
13. Morse Code (CW) ID sounds
QLF.
13. CW operator is a lid. 13. Recall your novice days.
