Exterior cleaning
CAUTION.
To prevent getting moisture inside the instrument during external
cleaning, use only enough liquid to dampen the cloth or applicator.
Do not use chemical cleaning agents that might damage the plastics used in
this instrument. Use only deionized water when cleaning the menu buttons or
front-panel buttons. Use a 75% isopropyl alcohol solution as a cleaner and
rinse with deionized water. Before using any other type of cleaner, consult your
Tektronix Service Center or representative.
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle
brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl alcohol
solution. Use a swab to clean narrow spaces around controls and connectors. Do
not use abrasive compounds on any part of the chassis that might damage the
chassis.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.
