NOTE:
The OHMD74 has an operating temperature of apr. 5 degrees C to 40 degrees C
(41 degrees F to 104 degrees F). If the temperature is outside this operating range,
the unit will turn on, or the screen may be slow to react to image changes.
The monitor will function normally once it returns to its proper operating
temperature range.
With a DVD player and a widescreen DVD disc, there are black bars on the screen.
Change the TV display mode to “WIDE” in the DVD player’s setup menu. After changing
this setting, if there are still black bars, press the MODE button on the OHMD74 remote
control.
