MECHANICAL INFORMATION
TOP COVER REMOVAL
If necessary, the interior of the instrument may be accessed by removing the four
Phillips screws on the top panel. With the four screws removed, the top cover may be
slid back (and off).
Always disconnect the power cord and allow the instrument to sit unpowered for 10
minutes before opening the instrument. This will allow any internal stored charge to
discharge.
There are no user-adjustable internal circuits. For repairs other than fuse replacement,
please contact Avtech ([email protected]) to arrange for the instrument to be
returned to the factory for repair.
Caution: High voltages (over 2000V) are present inside the instrument during
normal operation. Do not operate the instrument with the cover removed.
Caution: Do not remove the internal aluminum lid. It shields certain very-high-
voltage areas.
RACK MOUNTING
A rack mounting kit is available. The -R6 rack mount kit may be installed after first
removing the one Phillips screw on the side panel adjacent to the front handle.
