Chapter 9: Maintenance and Problem
Solving
This chapter provides information on routine maintenance and on possible
causes of problems you may experience with your HSB Series display unit.
9.1 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 LCD display is a sealed unit. Maintenance procedures are therefore
limited to the following periodic checks:
• Examine the cables for signs of damage, such as chafing, cuts or nicks.
• Check that the cable connectors are firmly attached.
Cleaning Instructions
Cleaning the Display
CAUTION:
Take care when cleaning the display. Avoid wiping the display screen
with a dry cloth - this could scratch the screen coating.
Do not use acid, ammonia based or abrasive products.
• Ensure power is off, wipe the display clean with a damp cloth.
• If necessary, use IPA (iso-propyl alcohol) or a mild detergent solution to
remove grease marks.
EMC Servicing and Safety Guidelines
• Raytheon equipment should be serviced only by authorized Raytheon ser-
vice technicians. They will ensure that service procedures and replacement
parts used will not affect performance. There are no user serviceable parts
in any Raytheon product.
