Cleaning
Use these procedures to clean your instrument. If additional cleaning is required, have your instrument serviced by qualified
service personnel.
Exterior cleaning
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.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or wet the switch directly.
CAUTION. Improper cleaning agents, methods, or excessive force can damage the instrument. Do not use chemical cleaning
agents that might damage the plastics used in this oscilloscope. Use only deionized water when cleaning the 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.
To prevent getting moisture inside the instrument during external cleaning, use only enough liquid to dampen the cloth or
applicator.
