Maintenance Information
NOTE: The LTC 8900 Allegiant system has been designed to perform for long periods of time
with little or no maintenance. Cleaning the keyboard or replacing a fuse may be necessary
occasionally. See instructions below.
Cleaning System Keyboard(s)
The keyboard may be cleaned whenever necessary by temporarily removing it from the system
and wiping it with a damp cloth. If a conventional spray cleaner is required, spray the cloth
first, then wipe the surfaces. Do not use petroleum-based cleaners, or cleaners containing
benzene, triclorethylene, ammonia, or acetone; these cleaners could damage the plastic
surfaces.
Matrix Bay AC Line Voltage Input Selection
The AC line voltage input selector is located on the rear of the equipment bay, inside the line
cord connector housing. The present input voltage selection is shown in the window of the
connector housing. Remove the AC line cord if the setting is incorrect. To change the setting,
insert a flat blade screwdriver into the slot 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, as in , page 101.
Figure 10.1: Voltage Selector
Reinsert the wheel into the connector housing so that the selected voltage is facing out. Snap
the door closed, and verify that the correct voltage selection is visible through the window.
Reattach the AC line cord.
