TROUBLESHOOTING

NO PICTURE, NO SOUND

The A7 system has low- and high-voltage and temperature protection circuits. If the voltage or temperature goes beyond the limits, the system shuts off. The power wire or power harness may have been disconnected, or the fuse may have failed. Contact your Rosen authorized dealer to determine if this is the case.

Note: The system voltage range is 11-16VDC operating voltage. The system operating temperature is 0o to 50o Celsius. Use of the DVD Player beyond the safe operating ranges listed can cause temporary or permanent damage to the unit, and such damage may not be covered by the manufacturer’s warranty.

GOOD PICTURE, BUT NO SOUND OR DISTORTED, “TINNY” SOUND

Check the MUTE button. Check the volume on the radio, and make sure to try both 87.9 FM and 88.3 FM. Check the headphones; ensure the headphones have a direct “line of sight” to the infrared transmitter below the monitor. Replace headphone batteries, if needed. Check the DVD Setup Menu - the Audio Output setting must be set to “ANALOG” and the Speaker Downmix setting must be set to “STEREO”. If using a CD you have made yourself, make sure you did not set the recording level too high.

GOOD SOUND, BUT BLURRY PICTURE

This happens if the system components are very cold. Allow the interior of the vehicle to warm up before using the A7 system. Make sure that the DVD you are playing is in good condition. If using an optional source unit, check the manual for that unit.

NO RESPONSE WHEN PRESSING THE REMOTE BUTTONS

Check the battery in the remote control.

RADIO PLAYS STATIC OR HAS NO RECEPTION

Press SPEAKER to turn off the FM Modulator. “Headphone Sound Only” will appear on the screen. This should enable optimum radio reception.

THE DOME LIGHT ON THE A7 CONSOLE DOES NOT WORK

The dome light has a 5-minute timer to prevent accidental draining of the battery. You might need to replace the dome light bulb.

Note: There is a button on the remote that resembles the Dome Light button on the control panel. This remote-control button does not control the A7 dome light.

I HAVE BLACK BARS ON THE TOP AND BOTTOM OF MY SCREEN WITH A WIDESCREEN DVD.
