WARNING.
To prevent injury, power off the instrument and disconnect it from line
voltage before performing any cleaning.
Clean the exterior surfaces of the module 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 module. Do not use abrasive
compounds on any part of the chassis that may damage the chassis.
CAUTION.
To prevent damage, avoid the use of chemical cleaning agents which
might damage the plastics in this instrument. Use a 75% isopropyl alcohol
solution as a cleaner and wipe 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 module case. There are no user serviceable components inside
the module and cleaning the interior is not required.
Cleaning the Optical
Connectors
Small dust particles and oils can easily contaminate optical connectors and reduce
or block the signal. Take care to preserve the integrity of the connectors by
keeping them free of contamination.
CAUTION.
To prevent loss of optical power or damage to the optical connectors,
keep the connectors clean at all times.
To reduce the need for cleaning, immediately replace protective caps on the
optical connectors when not in use.
