Opretholdelse
- Hold enheden tør og væk fra fugt.
- Undgå at udsætte enheden for ekstreme temperaturer (varme eller kolde).
- Do not disassemble the device; this will void the warranty.
- Rengør enheden med en blød, tør klud. Brug ikke skrappe kemikalier eller slibende rengøringsmidler.
- Sørg for, at cigarettænderstikket er rent og fri for snavs for at opnå optimal forbindelse.
Fejlfinding
- Ingen strøm: Ensure the device is fully inserted into the car's cigarette lighter socket and that your car's ignition is on. Check if the car's fuse for the cigarette lighter is intact.
- Statisk eller dårlig lydkvalitet: Make sure the FM frequency on the transmitter matches your car radio's frequency exactly. Try different empty FM frequencies to find the clearest channel. Adjust the volume on both the transmitter and your car stereo.
- Bluetooth forbinder ikke: Ensure Bluetooth is enabled on your mobile device and the transmitter is powered on. Forget "BT99" from your phone's Bluetooth settings and try pairing again. Move your phone closer to the transmitter.
- Dårlig opkaldskvalitet: Ensure the built-in microphone is not obstructed. Reduce background noise in the car. The CVC noise cancellation feature helps, but extreme noise can still affect clarity.
- Enheden oplades ikke: Check that the USB cable is properly connected to both the transmitter and your mobile device. Ensure your device supports the charging standard (QC3.0 for fast charging).
Brugertips
- Stemmemeddelelser: The device may provide audible confirmations for actions like Bluetooth connection. This is normal operation and cannot be disabled.
- No AUX Output: This FM transmitter does not feature an AUX output port. Audio is transmitted wirelessly via FM frequency to your car's radio.
- Optimal FM Frequency: When selecting an FM frequency, try to find a channel that is completely clear of any radio stations to minimize interference and maximize sound quality.
