Introduction
The Clarion OHMD74 is a full-featured overhead entertainment center featuring DVD, CD, and MP3 playback. This system combines flexibility, reliability, and expandability all in one. Designed primarily for rear seat entertainment, the audio from the OHMD74 can be enjoyed privately through wireless headphones and/or incorporated into any head unit. And with the ability to access all the features and functions through an IR remote control, the rear passengers won’t have to leave the comfort and safety of their seats.
Since Clarion has always been an innovator in the mobile entertainment industry, a lot of responsibilities follow suit. One of the major emphasizes incorporated into the OHMD74 is reliability. This was achieved by using high-grade electronic components and heightened electronic connections. As the mobile environment is extremely harsh, these technological advances insure years of unrelenting operation.
Given that the OHMD74 is the centerpiece of the entertainment center, it features a built-in A/V switcher allowing for multiple A/V sources to be added. Included with the OHMD74, is a Game Port Station, which also can be used for a temporary device, such as a camcorder or game station, to be enjoyed in the vehicle.
With everything that Clarion has to offer with the OHMD74, it truly lives up to Clarion’s motto, BE SEEN, BE HEARD!

Temperature and Moisture
If the player is used while the interior of the vehicle is very cold, condensation may form on the disc or on the internal optical pickup system and prevent proper playing of the disc. If you suspect that condensation is an issue, eject the disc and inspect the playing surface. If necessary, remove the condensation with a clean soft cloth as described above. If you still experience problems with playback, you will need to wait for approximately one hour to allow the OHMD74 to warm up, and for the condensation to evaporate. If playback issues continue, please see your authorized Clarion dealer.
Discs Compatible with OHMD74
The OHMD74 supports and plays DVD (Region 1), VCD, CD, CD-R, and MP3 formats. Although the OHMD74 is designed to play DVD’s, DVD’s are manufactured to respond to the particular Region Management Information they are created in. The OHMD74 is compatible with Region 1 and “ALL” Region DVD’s. The DVD/CD mechanism can accept both 5” (12cm) and 3” (8 cm) single sided discs.
