The instrument should be cleaned as often as operating conditions require.
Dirt in the instrument can cause overheating and component breakdown.
Dirt on components acts as an insulating blanket and prevents efficient heat
dissipation. Dirt also provides an electrical conduction path which may
cause the instrument to fail. The side panels reduce the amount of dust that
reaches the interior of the instrument. Keep the side panels in place for
safety and cooling.
CAUTION
Avoid the use of chemical cleaning agents which might damage the
plastics used in this instrument. Use a nonresidue type of cleaner,
preferably isopropyl alcohol or totally denatured ethyl alcohol.
Before using any other type of cleaner, consult your local Tektronix
service center or representative.
Exterior
Dust on the instrument can be removed with a soft cloth or small brush. The
brush is also useful for dislodging dirt on and around the front panel conĆ
trols. Dirt that remains can be removed with a soft cloth dampened in a mild
detergent and water solution. Do not use abrasive cleaners.
CRT
Faceplates are cleaned with a soft, lintĆfree cloth dampened with denatured
alcohol.
