1. INTRODUCTION
The Clarion OHM653 is a high-performance video monitor
designed specifically for the mobile environment. It is
intended for use with other Clarion multimedia products, and
can also be integrated with many other products as part of a
complete mobile video solution. With two video inputs, the
OHM653 can support simultaneous connection to both
dedicated video source units and optional audio/video
components such as camcorders or videogames. The
infrared remote control receiver output allows integration with
select Clarion DVD and VHS source units.
The OHM653 automatically switches to operate with either
NTSC or PAL video signals (NTSC is the standard North
American video format).
The 16:9 aspect ratio screen allows DVD films to be viewed
in their original aspect ratio for the best cinematic experience.
Note:
• The OHM653 is designed to be a component in a full audio/video
system. If you have any questions about compatible components,
such as system controllers, source units, FM modulators, or
other audio/video products, please contact your authorized
Clarion dealer.

The OHM653 has built-in dome lights which may replace the
original ceiling-mounted lights in some installations. These

the doors are closed (some vehicles have domelight-delay
systems that keep the light illuminated for a few seconds
after the doors are closed). The OHM653’s lights may be
manually turned on and off with a sliding switch built into the
monitor.

do not leave the dome light switch in the
