PRECAUTIONS

1. This set is for use in DC 12V, negative ground vehicles.

2. Do not operate the set in ways other than described in this guide. Doing so
may damage it and may void your warranty.

3. SAFETY FIRST! For rear seat overhead use only. Do not install anywhere
that would permit monitor to be viewed by the driver. Monitor must not be
located in the motor vehicle at any point forward of the back of the front
seats. Monitor must never be used in any manner that will distract driver or
interfere with driver’s safe operation of the motor vehicle.

4. Be careful not to run down the car battery while using the set with the car
stopped.

5. Do not disassemble or modify the set. Doing so may damage it and voids
your warranty.

6. Keep drinks and drops from umbrellas away from the set. Water may
damage the internal circuitry.

7. Do not let the set become hot. If temperature in the car is high or the set has
been exposed to direct sunlight and is hot, lower the temperature before
using it. (The liquid crystal panel will work properly within a temperature
range of 30 – 113 degrees F.)

8. In extremely cold temperatures, the movement of the picture may be slow
and the picture may be dark, but this is not a malfunction. The set will work
normally once the temperature increases.

9. Small black and shiny dots inside the liquid crystal panel are normal for
liquid crystal products.

WIRING PRECAUTIONS

Read all wiring precautions. If you are not sure of the connections, contact
your authorized Clarion dealer.

1. Disconnect the negative (-) lead of the battery before making any power

connections.

2. When creating passage holes for the power wires, use grommets to

eliminate any sharp edges created during drilling. This will protect the wire
from being nicked and causing a short circuit.

3. When connecting the ground lead, fasten the ground lead (black) securely

to a clean metal plate on the vehicle.

NOTE: The OHM641 mointor displays video images only. It does not provide audio output. Refer to the
owner’s manual of the connected device for information on audio output.

INSTALLATION

The OHM641 is an overhead, fold-down 6.4” monitor with an Infrared (IR)
eye. It will accept a video signal from any video source with composite video
out. The IR eye will work directly with the TTX001, VDH9600 and DVD9600.

1. Look over the vehicle for a location for the monitor. Each vehicle is
different and locations will vary. Make sure the monitor will not interfere
with the dome light, wiring, water channels or sunroof operation. The
mounting bracket has slots to accomodate various dome light screw
patterns. In some cases, the vehicle dome light may need to be relocated.

2. Once a location has been determined, run the IR extension, video RCA and
power cables above the head liner to the mounting location.

3. Feed the cables through the hole in the mounting bracket and screw the
bracket to dome light mounting rib. Use short screws so as not to damage
the roof.
