5 MAINTENANCE

WARNING

Dangerous voltage and invisible laser radiation

Maintenance or cleaning of the instrument while it is con­nected 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.

5 MAINTENANCE

CLEANING THE TEST PORT

For daily use, clean the optical interface of the instrument using
Viavi IBC cleaning tool 2.5 mm (see “Cleaning materials, power

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.

NVIRONMENTAL MANAGEMENT PROGRAM

Viavi Environmental Management Program

Superb performance and high quality have always characterized
Viavi datacom and telecom measurement technology products.
In this same world-class tradition, Viavi has an established,
proactive program of environmental management.

Environmental management is an integral part of Viavi’s
business philosophy and strategy requiring the development of
long-term, productive solutions to problems in the key areas of
economics, technology, and ecology.

A systematic environmental management program at Viavi is
essential in regard to environmental policy and enhances
cooperation between ourselves and our business partners.

The Viavi Environmental Management Program
considers:

Product design and manufacture

Environmental restrictions and requirements are taken into
account during planning and manufacture of Viavi products.
This attention ranges from the raw materials and finished
components selected for use and the manufacturing processes
employed, through to the use of energy in the factory, and right
on up to the final stages in the life of a product, including
dismantling.

Hazardous materials

Viavi avoids or uses with care any hazardous or dangerous
material in the manufacturing process or the end product. If the
use of a dangerous material cannot be avoided, it is identified in
product documentation and clearly labeled on the product itself.

Packaging materials

Preference is given to reusable or biodegradable single­substance packaging materials whenever possible.

Environmental management partnerships

Viavi encourages our customers and suppliers who take this
responsibility seriously to join Viavi in establishing their own
environmental management programs.
