Troubleshooting

Maybe, it will happen that your headunit will not function as you expected it to be. Before calling for service, please read this user manual and review carefully the setting values. You may find that a function cannot work properly with the values you defined. Nevertheless, if you need to send your headunit for reparation, always send it complete with detachable front (do not try to open the headunit to service it by yourself).

In the case whereby your headunit freezes, please flip down the front and use a pen or pen- cil to poke the "RESET" hole.
