Chapter 7: Maintenance and Problem
Solving
This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your display unit.
7.1 Maintenance
WARNING:
The display unit contains high voltage. Adjustments require specialized
service procedures and tools only available to qualified service
technicians - there are no user serviceable parts or adjustments and the
operator should not attempt to service the equipment. The operator
should not remove the rear cover of the display.
Switch off the display unit before removing the power cord.
Routine Checks
The display is a sealed unit. Maintenance procedures are therefore limited to
the following periodic checks:
• Wipe the display clean with a damp cloth (ensure power is off).
• Examine the cables for signs of damage, such as chafing, cuts or nicks.
• Check that the cable connectors are firmly attached.
