6.USING REMOTE CONTROL
Inside the vehicle, simply aim the IR Remote Control directly at the OHM733/OHM833,
or at a Clarion monitor, or video source with an IR eye input and press any desired
button for better results. Also note the following:
●Aim the IR Remote Control from no further than 2 Meters away and no more than 0.9 Meters
on either side of the sensor.
●Direct sunlight or very bright light will reduce sensitivity to the IR remote signal commands.
Be sure the monitor is not located in direct sunlight.
●Objects between the monitor will interfere or block IR remote signal commands.
7.INSERTING THE BATTERIES
1. Locate the battery compartment on the back of the IR Remote Control.
2. Remove the battery holder and insert two AAA alkaline batteries matching polarity
as shown inside the battery holder.
3. Snap the battery holder back into the remote unit until it locks with a click.
8.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 wire) securely to a clean
metal plate on the vehicle.
NOTE: The OHM733/OHM833 monitor displays video images only. It does not provide audio output.
Refer to the owner’s manual of the connected device for the information on audio output.

with Clarion video source products with an IR eye input.(Please check first if Adapter is necessary!).
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 driver.
2. Run necessary wires to the mounting location. When necessary cut the headliner and pull
wires through.
3. Use a 30cm x 30cm x 2cm or 1.2cm think piece of plywood to mount the OHM733/OHM833.
4. Silicone the piece of plywood to the top of the roof or screw the plywood to the dome light
mounting assembly and or the roof support rail.

sources.
7. Make sure all wires and DIN cables are way from screws when drilling.
8. Screw the monitor and universal pod assembly (factory pre-assembled) into the plywood using
4 wood screws (not supplied). Use the shortest screws possible to prevent roof penetration.
