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.
Refer to the
Pathfinder Radar Scanner Owner’s Handbook for scanner
maintenance details.
9.1 Maintenance
Warnings
The display unit and scanner unit contain high voltage . Adjustments
require specialised 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 or any internal
covers in the scanner.
Always turn the radar system off before carrying out any routine
maintenance on the scanner or nearby equipment. 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 periodical 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.
EMC Servicing and Safety Guidelines
• Raytheon equipment should be serviced only by authorised Raytheon
service engineers. They will ensure that service procedures and replacement
parts used will not adversely affect performance. There are no user
serviceable parts in any Raytheon product.
• High voltages are generated in both the scanner and the display unit. Never
handle the cables/connectors when power is being supplied to the
equipment.
• Always report any EMC related problem to your nearest Raytheon dealer.
We will use any such information to improve our quality standards.
