18 Maintenance Information

18. 1 Cleaning the Keyboard

18.2 AC Line Voltage Input Selection

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.
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.
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.

Remove the voltage selector wheel from the connector housing and rotate until the
desired voltage is visible.
Reinsert the wheel back into the connector housing so that the selected voltage is
facing out. Snap door closed and verify that the correct voltage selection is visible
through the window. Reattach AC line cord.
