Cleaning

The module case keeps dust out and should not be opened. Cleaning the exterior
of the main module is usually confined to the front panel. If you need to clean
the case, remove the module from the main instrument but first read the entire

Installation

procedure starting on page 6 for proper handling of the module.

WARNING.

To prevent injury, power down the instrument and disconnect it from

line voltage before performing any cleaning.

Clean the exterior surfaces of the modules or cables with a dry lint-free cloth or
a soft-bristle brush. If any dirt remains, use a damp cloth or swab dipped in a
75% isopropyl alcohol solution. Use a swab to clean narrow spaces around
controls and connectors. Do not allow moisture inside the modules. Do not use
abrasive compounds on any part of the cases or cables that may damage them.

CAUTION.

To prevent damage, avoid the use of chemical cleaning agents which

might damage the plastics used in this instrument. Use a 75% isopropyl alcohol
solution as a cleaner, and rinse with deionized water. Use only deionized water
when cleaning the menu buttons or front-panel buttons. Before using any other
type of cleaner, consult your Tektronix Service Center or representative.

Do not open the case of the module or the remote modules. There are no user
serviceable components and cleaning the interior is not required.
