Cleaning the Scanner

To keep the 751G in good working order, you may need to clean the EA11 scanner window.

Clean the scanner window as often as needed for the environment in which you are using the 751G. To clean the 751G, use a solution of ammonia and water.

There are no user-serviceable parts inside the 751G. Opening the unit will void the warranty and may cause damage to the internal components.

Press the power switch to turn off the 751G. Dip a clean cloth towel in the ammonia solution and wring out the excess. Wipe off the scanner window, wipe dry. Do not allow abrasive material to touch this surface.
