Operation Steps - Sharp QA1150 Operation Manual

Operation Steps
Before turning power on to the equipment, please note the following precautions.
The QA-1150 should not be used with any overhead projector which may cause
the panel's internal LCD to reach a temperature of 45°C (113°F) or higher.
To prevent the QA-1150's LCD from reaching this maximum temperature, a very effective
cooling fan is built into the panel. This fan only operates when the QA-1150's power switch is
turned ON. Therefore, make sure that the QA-1150 power switch has been turned on first and
then turn on the power switch of the overhead projector.
Because the QA-1 150 is directly compatible with many systems, it has been provided with a
built-in Automatic Setup System to enable correct display for most display signals.

NOTES
(1) VGA (720-dot display)
When using a VGA card in the 720-dot mode, the QA-1150 will compress the image
to 640 dots. To view the image in the 720-dot mode, press the COMP button on the
remote control unit. Only 640-dots will be displayed. To check the remaining portion
of the image, select H-POS mode, and use the shift V button on the QA-1150 panel
or the - button on the remote control to shift the image left by 80 dots. Pressing the
COMP button again returns back to the 640-dot compressed display mode.
(2) MDA, Hercules®
The QA-1150 does not compress these display modes. The QA-1150 will display 640
out of 720 dots. To view the remaining portion of the image on the right side, use the
shift V button on the QA-1150 panel or the - button on the remote control unit io
shift the image left by 80 dots.
