If your unit does not have an automatic clock setting, press and hold the DISP button until the hour digits flash. Rotate the volume knob to adjust the hours, then press DISP again to set minutes. Press and hold DISP to save.
Why is there no sound coming from the speakers?
Check the speaker wiring connections. Ensure the unit's MUTE function is off and the volume is not at zero. Also verify that the FADER and BALANCE settings are centered. If these are correct, test if the built-in amplifier fuse has blown.

Clean the front panel and display with a soft, dry microfibre cloth. Avoid using alcohol or ammonia-based cleaners. Periodically check that the ISO connectors and antenna plug are securely fastened. Keep the fan vents free of dust.
Can I use the FM radio function in areas with weak signals?
If you experience weak FM reception, ensure the vehicle antenna is fully extended and properly connected. You can also enable LOCAL mode in the tuner settings to attenuate weaker stations and reduce noise, improving overall clarity.
