What do I need for proper cleaning? Cleaning Instructions
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition 427
We recommend that you do not use normal cotton tissues, but multi-
layered soft tissues made from non-recycled cellulose. Cellulose tissues 
are very absorbent and softer. Consequently, they will not scratch the 
surface of your device over time.
Use care when cleaning, and avoid pressing on your optical device with 
the tissue. Pressing too hard may lead to scratches on the surface or 
misalignment of your device. Just rub gently over the surface using a small 
circular movement.
Use only clean, fresh soft tissues and never apply them twice. Any dust 
and dirt from the air which collects on your tissue, or which has gathered 
after initial cleaning, may scratch and pollute your optical device.
Pipe cleaner
Pipe cleaners can be purchased from tobacconists, and come in various 
shapes and sizes.The most suitable one to select for cleaning purposes 
has soft bristles, which will not produces scratches.
There are many different kinds of pipe cleaner available from tobacco 
shops.
The best way to use a pipe cleaner is to push it in and out of the device 
opening (for example, when cleaning an interface). While you are cleaning, 
you should slowly rotate the pipe cleaner.
Only use pipe cleaners on connector interfaces or on feed through 
adapters. Do not use them on optical head adapters, as the center of a pipe 
cleaner is hard metal and can damage the bottom of the adapter.
Your pipe cleaner should be new when you use it. If it has collected any 
dust or dirt, this can scratch or contaminate your device.
The tip and center of the pipe cleaner are made of metal. Avoid 
accidentally pressing these metal parts against the inside of the device, as 
this can cause scratches.
Compressed air
Compressed air can be purchased from any laboratory supplier.
It is essential that your compressed air is free of dust, water and oil. Only 
use clean, dry air. If not, this can lead to filmy deposits or scratches on the 
surface of your connector. This will reduce the performance of your 
transmission system.
