4. The Model GS-800 Calibrated Imaging Densitometer can operate with 100V AC to
240V AC. Check the power cord to insure that it is suitable for your area.
Caution: The power cord plug provided has a third grounding pin. This plug fits in a
grounding-type outlet only. This is a safety feature. If you are unable to plug the power
cord into a wall outlet, locate another outlet that can accommodate the plug or contact
your electrician to change the outlet. Do not change the plug.
2.3 Unlocking the Densitometer and the Transparency Module
The optical assembly of the Densitometer’s transparency module (located in the lid) is held
in place during shipment by a carriage lock (Figure 2.1) on the underside of the
transparency module. The carriage lock must be unlocked before the instrument will
work properly. Additionally, if the carriage lock is not unlocked prior to use, the optical
system may be damaged while scanning. Insert a coin into the Carriage Lock. Turn it
until the mark points align with the unlocked mark.
Note: Leave the locking screw in place so that it can be re-locked if you have to move the
Densitometer over long distances.

Warning: Always lower the transparency module slowly and release it only when it lies
flat on the body of the Densitometer.
