Surface-Lit AccuTab 7
The on/off power and dimmer control switches for the lighting are on the control
module found along the right side of the tablet. Set the power switch to the ON
position.
The light level is adjustable to three levels: LO, MED and HI. Select the level that is
most appropriate for your task, taking into consideration the material you are
lighting through and user comfort.
NOTE: A relatively stable AC power source is required for the illumination system to
function at maximum performance. If the light intensity of the Surface-Lit AccuTab flickers
periodically, it’s most likely due to a heavy electrical load being placed on the circuit, such
as a compressor or fan motor. This problem can be eliminated by using a separate circuit,
line conditioning equipment or a UPS power supply.
Replacing Light Bulbs on the Surface-Lit AccuTab
The expectancy life of a light bulb is approximately 2,000 hours of continuous use (a bulb
will illuminate at about 50% intensity after that time). Contact the GTCO CalComp by
Turning Technologies Technical Support Team to find out more about how to receive
replacement bulbs.
To install a replacement light
bulb(s):
1. Position the tablet parallel to
the floor with the top side
up. Unplug the power cord
from the ballast box.
