TROUBLESHOOTING

Issues described in the following table are some common operational failure. These types of errors are generally due to improperly connected, the operation caused by incorrect
settings, or operator error caused due to incomplete programming. These problems are usually not caused by circuit failure. Before suspect intercom failure, please refer to the
relevant parts of these forms and the instructions for use.
Question Possible Cause Solutions Reference page
Power did not respond.
1.the power cable is connected well.
2. the power cable fuse broken.
3. the voltage exceeds 17V or below 9V.
1, check the power cable is connected correctly: red (+); black (-).
2, then fi nd the cause of blown fuse, replace the fuse current to 15A.
3, adjust the power supply is 13.8V.
3
Unable to connect with GPS. 1. connection error.
2. different external GPS format.
1, check the connections are correct.
2, external GPS format should be NMEA0183-2.0.
3
Can not be scanned. Not set mark channels (TAG). The channel you want to scan is set to mark channels. 10
Can not launch. Work on the weather channel or 70 channels. Exit the weather channel or 70 channels. 4,8
High power can not be selected. Some channels can transmit at low power. Choose other channels. 5,7
The same channel can not talk.
1, the channel is different frequency (DUP).
2, the working group on its own channel.
1, select a channel.
2, the channel is set to the same frequency.
5,7
No beep Beep off Open the beep function in the settings mode. 22
Can not transmit a distress call. MMSI code is not set. Hold down the [DSC] key to boot into MMSI setting mode. 12
No sound from the speaker.
1, tone squelch level too.
2, the volume is too small.
3, the speaker grid water.
1, rotate [SQL] knob to adjust the squelch level.
2, rotate [VOL] knob to adjust the volume.
3, the use of vibration drainage water discharge.
