Troubleshooting of DMR Repeater
Phenomena 1 The repeater can not be powered on.
Analysis 1: Power cord is not connected or is not securely connected to the outlet.
Solution 1: Properly connect the power cord and ensure secure connection.
Analysis 2: Power cord fuse is damaged.
Solution 2: Check if the DC fuse has blown, and if yes, replace it with a new one.
Phenomena 2 Group members can not talk to each other, or the repeater can not communicate with a subscriber radio.
Analysis 1: TX/RX frequency of the repeater is inconsistent with that of portable/mobile terminals.
Solution 1: Re-set frequencies.
Analysis 2: Failed to repeat useful signal due to strong interference signal.
Solution 2: If you can not remove or bypass the interference source, change to operate on other frequencies.
Analysis 3: The group member is out of the coverage of the repeater.
Solution 3: Go within the coverage of the repeater.
Phenomena 3 Group members can not talk to each other, even though RX indication is given.
Analysis 1: Your ID is inconsistent with that of other group members.
Solution 1: Set your ID to the same as that of other members.
Analysis 2: Inconsistent CTCSS/CDCSS.
Solution 2: Re-set CTCSS/CDCSS.
Phenomena 4 Short communication range or poor audio
Analysis 1: Leakage of signal energy due to damaged connection cable.
Solution 1: Replace the cable with a new one if necessary.
Analysis 2: Loose connection between antenna connector and the cable, or loss of connection.
Solution 2: Secure the connection or replace cable plug with a new one if necessary.
Analysis 3: Invisible damage of cable.
