2. PRECAUTIONS  
Failure to observe these precautions may damage your car, the monitor, or the video  
source, and may void the warranty.  
For questions or problems not covered in this manual, contact your local Clarion Dealer.  
Operating  
Do not operate this product in ways other than those described in this manual.  
Failure to follow instructions may void the warranty.  
Do not use the unit with the ignition off. This could drain the car’s battery.  
If the internal temperature of the vehicle is extremely high (over 50 degrees  
Celsius), let the unit cool down a bit before you use it.  
If the temperature in the car is very low (below -5 degrees Celsius), starting the  
unit right after you start the car with its heater running may cause moisture to form  
on the LCD. Turn the unit off immediately! Failure to do so may cause an electrical  
short. Allow about one hour for the condensation to dissipate before using the unit.  
In extremely cold temperatures the picture may appear dark and move slowly. The  
display returns to normal when the temperature rises.  
When using the system, make sure you are seated with your seat belt fastened.  
Otherwise, you may hit your head on the unit if the driver breaks suddenly. In an  
accident, injuries can be more severe if your seat belt is not fastened.  
Before leaving the car, eject the DVD disc and store it separately away from direct  
sunlight. Heat and humidity can damage DVD discs causing them not to play.  
General  
Do not leave the monitor extended when you’re not using it. Direct sunlight can  
cause the monitor to malfunction.

Playing MP3s  
MP3, a format for storing digital audio, compresses each audio track with little loss of  
audio quality. The result takes up much less disc space than the track would without  
MP3 compression. The OHM875VD / OHM1075VD / OHM1575VD player supports CD-  
R/RW and DVD-R discs that contain music MP3 files.  
MP3 icons

Tools and additional components  
You will need a Phillips-head screwdriver when mounting the player in the vehicle.  
Before you begin  
1. Verify that the vehicle electrical components function, including: power windows,  
power door locks, air conditioning, lights, etc.  
2. Identify the polarity of the dome light circuit and set the switch on the bottom of the  
overhead monitor housing.  
3. Test fit the location of the overhead monitor system to ensure it will not interfere with  
the operation of the vehicle.  
4. If applicable, verify that the monitor, when mounted, will not interfere with the  
operation of the sun roof.  
5. Carefully mark the location with masking tape.  
6. Lower the vehicle’s headliner down to see if a roof support beam is available to  
screw the mounting bracket to.  
If a support beam is not available, use a 3/4-inch piece of plywood cut to the  
appropriate size. Attach the plywood to the roof of the vehicle using silicone. Allow  
for adequate drying time.  
7. Determine the location of any additional audio/video sources.  
8. Disconnect the negative battery terminal before making any wiring connections.  
CAUTION  
Do not open the case.There are no serviceable parts inside. If  
you drop anything into the unit during installation, consult with  
your Clarion Dealer or an authorized Clarion service center.  
Mounting and wiring precautions  
The OHM875VD / OHM1075VD / OHM1575VD should be mounted in the ceiling of  
the vehicle. The front panel controls should be easily accessible from the rear seat. In  
addition:  
This unit is exclusively for vehicles with a negative ground, 12V power supply.  
This unit may be in installed with additional mobile audio components, such as a  
digital camera.  
Always use great care when attaching anything to a vehicle! Check clearances  
on both sides of the planned installation before drilling any holes or installing any  
screws.  
A good chassis ground connection is critical to minimize resistance and avoid noise  
problems. Use the shortest wire possible and securely connect it to the car chassis  
and the source unit ground.

When routing RCA cables, keep them away from the power cables and output  
speaker wires, engine, exhaust system, etc. Heat may damage wires.  
If the fuse should blow, make sure that all connections are correct, the cables have  
not caused a short circuit, and no wires are damaged. Then replace the fuse with a  
new fuse of the same amperage value as the original fuse. When replacing a fuse,  
never let the battery side touch any metal part or any other wire.  
Never let disconnected cables or terminals touch metal on the car or any other  
conducting material.  
To prevent short circuits, do not remove the caps from unused terminals or from the  
ends of unconnected cables.  
Insulate unconnected wires with vinyl tape or other similar material.  
WARNING!  
To prevent short circuits during installation, disconnect the  
vehicle’s negative (-) battery lead before making any power  
connections.  
Installation procedure  
The OHM875VD / OHM1075VD / OHM1575VD replaces the car’s dome light. This  
section provides basic tips and techniques to aid the installation. These are not vehicle  
specific, but should be used as guidelines for performing the installation.  
Set the polarity switch  
1. Determine the polarity of the power system in the car. This information should be on  
a vehicle-specific diagram.  
2. Locate the polarity switch on the back of the player (the side that will be attached to  
the ceiling).
