OLS-3XV2 OP TICAL LIGHT SOURCES

1 INTRODUCTION

OLS-3xV2 Optical Light Sources

The Test Sets are specially designed for high performance testing
of all systems, i.e. broadband, PONs, and Gigabit Ethernet.

Battery operation from two AA batteries and the robust, shock­proof design provide long operating time in the field even under
tough conditions. AC line operation via a separate AC adapter
and the USB interface ensure ease of use in the laboratory or
production environment.

3 GETTING STARTED

Unpacking the device

Packing material

We suggest that you keep the original packing material. It is
designed for reuse (unless it is damaged during shipping). Using
the original packing material ensures that the device is properly
protected during shipping.

Checking the package contents

Your device is shipped with the following accessories:

• 2 dry batteries AA

• Operating manual

• Belt bag

Checking for shipping damage

After you unpack the device, check to see if it has been damaged
during shipping. This is particularly likely if the packaging is
visibly damaged. If there is damage, do not attempt to operate
the device. Doing so can cause further damage. In case of
damage, please contact your local Viavi Sales Company.
Addresses can be found at www.viavisolutions.com.

UNPACKING T HE DEVI CE

Recovery following storage/shipping

Condensation can occur if a device that is stored or shipped at a
low temperature is brought into a warm room. To prevent
damage, wait until no more condensation is visible on the
surface of the device before powering it up. Do not operate the
device until it has reached its specified temperature range and
wait until it has cooled down if the device was stored at a high
temperature (see “Enviromental conditions” on page 26).

Battery operation

WARNING

Dangers when handling batteries

Handling batteries may be dangerous. Please note the
following safety instructions.

J Please note the battery operation safety information in the

section “Battery operation” on page 9.

Replacing the batteries

J Do not replace individual batteries. Always change both

batteries at the same time.

J Always use batteries of the same type; i.e. do not mix

rechargeable and non-rechargeable batteries.

Replacing batteries
The battery compartment is on the back of the device.

1. Pull down the lid to open the battery compartment.

NOTICE: Take care to insert the batteries correctly. The correct
polarity is indicated by a diagram inside the battery
compartment.

2. Insert new batteries or replace dead ones.

3. Close the battery compartment.

4. Press

[E] to switch on.

NOTE: The batteries cannot be recharged with the OLS-3xV2.

General tips on using batteries

• Never use batteries based on lithium.

• Always handle batteries with care.

• Do not drop or damage the batteries or expose them to
excessively high temperatures.

• Do not store rechargeable batteries for more than one or two
days at very high temperatures (e.g. in a vehicle), either
separately or fitted in the device.

• Do not leave discharged batteries in the instrument for a long
time if it is not being used.

• Do not store rechargeable batteries for more than 6 months
without recharging them at intervals.

• Avoid deep discharging of the batteries as this can cause the
cell polarity to reverse and make the battery useless.

Protecting the environment

Please dispose of any unwanted dry batteries and rechargeable
batteries carefully. They should also be removed from the
instrument if it is to be scrapped. If facilities in your country exist
for collecting waste or for recycling, please make use of them
rather than throwing the batteries in the normal trash. You will
often be able to return used batteries to the store where you
purchase new ones. Any dry or rechargeable batteries that you
purchased from Viavi can be returned to one of our Service
Centers for disposal.

6 MAINTENANCE

WARNING

Invisible laser radiation

Maintenance or cleaning of the instrument w hile it is
connected or operating may damage the instrument or
injure you.

J Make sure that the instrument is switched off and

disconnected from all power sources and optical radiation
sources before maintenance or cleaning.

J Do not open the instrument for maintenance or service.

Service shall be performed by Viavi trained personnel only.

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 “Cleaning materials, power

supplies” on page 27).

6 MAINTENANCE

CLEA NING T HE TEST PORT

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.

6 MAINTENANCE
CLEA NING T HE I NSTRUMENT

Cleaning the instrument

If the device gets dirty through use, you can clean it using a soft
cloth moistened with a mild solution of detergent.

NOTICE

Water and cleaning fluids

The instrument may be damaged or destroyed if water or
cleaning fluids penetrate it.

J Make sure that water or cleaning fluids do not get inside the

device.

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 single-

substance 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.
