WARNING
Dangerous voltage and invisible laser radiation
Maintenance or cleaning of the instrument while it is con-
nected or operating may damage the instrument or injure
you.
► Make sure that the instrument is switched off and
disconnected from all power sources and optical radiation
sources before maintenance or cleaning.

Cleaning the test port

It is a good idea to check that the optical connections are clean
and to clean them if necessary before starting measurements.
Even very small dust particles on the end surfaces of the plugs or
in the test adapters can adversely affect the accuracy of the
measurement.
For daily use, clean the optical interface of the instrument using
Viavi IBC cleaning tool 2.5 mm (see
supplies" on page 32).
To clean the test port in case of severe contamination:
1. Switch off the device.
2. Remove the test adapter from the optical connection. The
connection surface is now accessible.
3. Wipe off the connection surface using a cotton bud soaked in
isopropanol. This cleaning method is very effective and leaves
no residues.
4. Blow out the test adapter with clean compressed air (also
available in spray cans, e.g. Anti Dust Spray).
Note: Cover the optical connections with the dust cap
whenever they are not in use. This prevents them from
getting dirty.
