What to do if there is no audio output from my Bosch PRM-UST Tuner?
If your Bosch Tuner isn't producing any audio, ensure the audio output cable is properly connected. Check the output control setting on the rear panel. Clean any dust or dirt from the audio output connectors or plugs. Also, verify that the selected source is not in pause or mute mode; if it is, press the play or mute button.
Why is the audio output distorted on my Bosch PRM-UST?
If the audio output from your Bosch Tuner is distorted or noisy, ensure the audio output cable is properly plugged into one of the stereo RCA output connectors. Also, make sure the connectors and plugs are clean; wipe away any dust or dirt and reinsert the plug.
What to do if my Bosch PRM-UST doesn't detect USB or SD storage device?
If your Bosch Tuner isn't detecting a USB or SD storage device, it might not comply with USB mass storage standards. Try using a device that does. Avoid USB hubs, or connect the storage device directly to the USB port. Ensure you're using FAT, FAT32, or exFAT file structure. If an electrical current stronger than allowable was applied to the unit’s USB socket, wait several minutes. The rating (allowable current) for this unit is 500 mA or less per USB port. Reformat the USB or SD card with a PC that has been known to give good results.
