Cleaning Information
How to clean instruments with a recessed lens interface
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
2. Clean the interface by rubbing a new, dry cotton-swab over the 
surface using a small circular movement.
3. Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly 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.
