How to clean instruments with a fixed connector interface
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the 
lens:
1. Moisten a new cotton-swab with isopropyl alcohol.
2. Clean the lens by rubbing the cotton-swab over the surface using 
a small circular movement.
3. Using a new, dry cotton-swab remove the alcohol, any dissolved 
sediment and dust.
4. Blow away any remaining lint with compressed air.
E.12 How to clean instruments with a fixed 
connector interface
You should only clean instruments with a fixed connector interface 
when it is absolutely necessary. This is because it is difficult to 
remove any used alcohol or filaments from the input of the optical 
block.
It is important, therefore, to keep dust caps on the equipment at all 
times, except when your optical device is in use. 
If you do discover filaments or particles, the only way to clean a 
fixed connector interface and the input of the optical block is to use 
compressed air.
If there are fluids or fat in the connector, please refer the instrument 
to the skilled personnel of Agilent’s service team.
CAUTION Only use clean, dry compressed air. Make sure that the air is free of 
dust, water, and oil. If the air that you use is not clean and dry, this can 
lead to filmy deposits or scratches on the surface of your connector 
interface. This will degrade the performance of your transmission 
system.
