Guide to Backlight Replacement

Under normal conditions it can be assumed that the backlight will need to re-
placed after about 20,000 hours. However, the life of the backlight does vary in
accordance with the environment in which it is used and it should be replaced
when it is getting dim and the screen is getting hard to read.

Replacing the Backlight

WARNING: Turn off the power before replacing the backlight. Otherwise you could sustain an

electric shock.

Operation

1. Switch the power to the NT20S off, remove the screw from the backlight re-

placement cover using a Philips screwdriver, and open the cover. Then dis-
connect the backlight connector from the NT20S.

2. Pull out the T-shaped backlight loading tool and replace the backlight.

3. Re-install the backlight and connect its connector to the NT20S.

Close the cover and tighten the screw with a flat-head screwdriver.
