Power Supply
1. The rear projection display is designed to operate on a power supply
of 100-120 or 200-240 V 50/60 Hz AC. Ensure that your power sup-
ply fits this requirement before attempting to use your rear projection
display.
2. Handle the power cable carefully and avoid excessive bending. A
damaged cord can cause electric shock or fire.
3. If the rear projection display is not to be used for an extended period
of time, disconnect the plug from the power outlet.
Cleaning
1. Unplug the rear projection display before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled,
use a mild detergent. Never use strong detergents or solvents such
as alcohol or thinner.
3. Be careful not to scratch or mar the screen face.
CAUTION
Do not unplug the power cable from the wall outlet under any one of
the following circumstances. Doing so can cause damage to the rear
projection display:

sage will be displayed after the rear projection display is turned
off.
* Immediately after the power cable is plugged into the wall outlet
(the POWER indicator has not changed to a steady amber glow).
