Cleaning the Keyboard
18 Maintenance Information
The Allegiant system has been designed to perform for long periods of time with lit- tle or no maintenance. Occasionally the need will arise to clean the keyboard, or replace a fuse. Follow the instructions below if any of these items are required.
18.1 Cleaning the Keyboard
The keyboard may be cleaned whenever deemed necessary simply by temporarily removing it from the system and wiping it with a damp cloth. If a conventional spray type cleaner is required, spray the cloth first, then wipe off the surfaces. Do not use petroleum based cleaners or cleaners containing benzene, triclorethylene, ammonia or acetone, as these cleaners could damage the plastic surfaces.
18.2 AC Line Voltage Input Selection
The AC line voltage input selector is found on the rear of the equipment bay inside the line cord connector housing. The present input voltage selection will be shown in the window of the connector housing. Remove AC line cord if the setting is incor- rect. To change the setting, insert a flat blade screwdriver into the slot located at one end of the connector housing as indicated in the drawing and rotate the screwdriver until the door to the housing opens.
