Disassembly Guidelines
WARNINGS
REPAIR TO THE FRU LEVEL — Field repairs are
recommended to the field replaceable unit (FRU) only.
Attempting a field repair on a PCB or a factory sealed
component or assembly could jeopardize the safe and
effective operation of the monitor.
BATTERY EXPLOSION HAZARD — When removing
the GCX plate and the footpad from the bottom of the
monitor, clearly identify the screws to ensure the same
screws are used to replace both the footpad and the GCX
plate. Do NOT re-assemble the footpad without the GCX
plate. Screws that are too long will penetrate into the
battery case and cause the battery to leak or to explode.
Tools Required
A standard set of hand tools is required for disassembly and assembly.
Before Disassembly Before you disassemble the monitor, you should ALWAYS:
• Remove AC power.
• Remove both batteries.
• Provide appropriate electrostatic discharge protection to prevent
damaging the monitor.
• Be aware that the nonspecific disassembly instructions apply to all
Dash monitors supported by this service manual. Disassembly for
specific models of the Dash monitor are identified when required.
Hardware
Assemblies When disassembling the monitor, observe the following guidelines:
• Remove the handle assembly, then remove the display assembly to
access the field replaceable or upgradeable components of the display
assembly and the main unit.
• Note the positions of wires, cables, and different sized screws;
marking them if necessary to ensure they are replaced correctly.
