■ CLEANING PROCEDURES
Keep your dust and shutter caps on when your instrument is not
in use. This should prevent it from getting too dirty. If you must
clean such instruments, please refer the instrument to the
skilled personnel of Agilent's service team.
Preferred Procedure
Use the following procedure on most occasions.
1. Blow away any dust or dirt with compressed air.
If this is not sufficient, then
a. Clean the interface by rubbing a new, dry cotton swab
o v e r the surface using a small circular movement.
b. Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure when there is greasy dirt on the interface,
and using the procedure for light dirt is not sufficient. Using
isopropyl alcohol should be your last choice for recessed lens
interfaces because of the difficulty of cleaning out any dirt that
is washed to the edge of the interface.
1. Moisten a new cotton swab with isopropyl alcohol.
2. Clean the interface by rubbing the cotton swab over the
surface using a small circular movement.
3. Take a new, dry soft tissue and remove the alcohol, dissolved
sediment and dust, by rubbing gently over the surface using
a small circular movement.
4. Blow away any remaining lint with compressed air.
