CDR500 & CDR700 Repeater Service Manual
Symptom
1. No "Rx" LED indication when
signal is received.
2. No "Tx" LED indication in re-
peater mode when properly
identified signal is received or
transmit radio does not key.
3. Some field radios can not access
telephone.
4. Transmit radio keys but low or
no audio is transmitted.
5. No "Phone" LED indication
when attempting to access tele-
phone line (PSTN).
6. ZR340 will not pulse dial PSTN

cessory connector of receive ra-
dio.
1b. Loose or bad repeater cable to re-
ceive radio.
1c. JP7 and/or JP8 in ZR340 in
wrong position(s).

cessory connector of receive ra-
dio.

cessory connector of transmit ra-
dio.

connector programmed incor-
rectly.

dios.

ZR340 not adjusted correctly.
4b. "Accessory Mic Gain" set too
low in transmit radio.
4c. "Ext PTT Audio" source incor-
rect.
5a. Improper programming of field
radios or ZR340.
5b. Wrong access code transmitted
by field radios.
6a. Not programmed for pulse dial.
6b. Too much time has elapsed be-
tween digits.

Troubleshooting
Possible Solution(s)
1a. Reprogram:
• Pin 4 ("CSQ Detect," active
"High")
• Pin 12 ("PL and CSQ Detect/
Talkgroup Detect," active
"Low").
1b. Check cable connections and re-
place cable, if necessary.
1c. Check position(s) and correct.
2a. Reprogram correct "Rx Squelch
Code."
2b. Reprogram:
• Pin 4 ("CSQ Detect," active
"High")
• Pin 12 ("PL and CSQ Detect/
Talkgroup Detect," active
"Low").
2c. Use DTMF to select half-duplex
and repeater enabled (40# then
18#).
2d. Reprogram:
• Pin 4 ("CSQ Detect," active
"High")
• Pin 12 ("NULL," active Low").
2e. Reprogram pin 3 for "External
Mic PTT".
2f. Wait for channel to clear.
3a. Check "Rx" (receive) control set-
ting of ZR340.
3b. Reprogram field radios.
3c. Reprogram field radios or reed-
ucate radio users.
3d. Readjust DTMF deviation for
60% to 70% rated system.
4a. Adjust "Rx" and/or "Tx" con-
trol(s) on ZR340.
4b. Reprogram "Accessory Mic
Gain".
4c. Reprogram for "Ext Mic Audio.
5a. Reprogram field radios or
ZR340.
5b. Reprogram field radios or reed-
ucate radio users.
6a. Reprogram the ZR340.
6b. Do not allow more than 5 sec-
onds between digits.
6c. One step above calling "Ernes-
tine".
7a. Readjust DTMF deviation for
60% to 70% of rated system devi-
ation.
7b. Reset "Rx" control on ZR340.
