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. Service is to be performed solely by qualified service
personnel.
Caution: High voltages are present inside the instrument during normal operation.
Do not operate the instrument with the cover removed.
RACK MOUNTING
A rack mounting kit is available. The -R5 rack mount kit may be installed after first
removing the one Phillips screw on the side panel adjacent to the front handle.
ELECTROMAGNETIC INTERFERENCE
To prevent electromagnetic interference with other equipment, all used outputs should
be connected to shielded loads using shielded coaxial cables. Unused outputs should
be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to
prevent unintentional electromagnetic radiation. All cords and cables should be less
than 3m in length.
