6 m away at a 15° angle.
b) Check the batteries in the remote control and replace them if

When these words appear on the screen (or a variation), follow
these steps:
Step 1: The fixed current of the vertical frequency exploration on
the LCD screen may be out of display range. Please adjust the
vertical frequency exploration of your LCD screen in the following
way:
Resolution 640 x 480 + vertical frequency: 60 Hz+ horizontal
frequency 31.5 kHz
Step 2: If you have not fixed the problem after following step 1
and your LCD monitor has multiple input ports, set the input port
on analog VGA mode.
The standard VGA signal for COM-250 is identical to the general
VGA PC card. Because of this, this unit will not void the
warranty on your LCD or CRT monitor.
