Mechanical Disassembly

For procedures in this section, the following tools are required for 
disassembly:

•

T20 Torx driver (most disassembly)

•

#2 Pozi- drive screw driver

•

Flat blade screw driver

General disassembly

1

Turn off the power. Remove all cables from the instrument.

2

Remove the carry handle.

 Rotate the handle upright and pull out from 

the sides of the instrument.

WA R N I N G

SHOCK HAZARD. Only service-trained personnel who are aware of 
the hazards involved should remove the instrument covers. To avoid 
electrical shock and personal injury, make sure to disconnect the 
power cord from the instrument before removing the covers. Some 
circuits are active and have power applied even when the power 
switch is turned off.
