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.
