6. USING REMOTE CONTROL
Inside the vehicle, simply aim the IR Remote Control directly at the OHM720/
OHM820, 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:
l Aim the IR Remote Control from no further than 7 feet away and no more
than 3 feet on either side of the sensor.
l 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.
l 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 OHM720/OHM820 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.
OWNER’S MANUAL
9. INSTALLATION INSTRUCTIONS
The OHM720/OHM820 is an overhead, flip-down 7"/8” 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 any Clarion video
source product with an IR Eye Input.
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 12"W x 12"L x ½" or ¾" thick piece of plywood to mount the
OHM720/OHM820.
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.
5. Once the plywood has been mounted, connect the IR, power and DIN
cables to the designated sources.
6. Make sure all wires and DIN cables are way from screws when drilling.
7. Screw the monitor and universial pod assembly (factory pre-assembled)
into the plywood using 4 wood screws (not supplied). Use the shortest
screws possible to prevent roof penetration.
