OLS-3XV2 OPTICAL LIGHT SOURCES
1 INTRODUCTION
1INTRODUCTION
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, shock-
proof 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.
Differences between the devices
The OLS-3xV2 family covers all the modes, wavelengths and
fiber types needed. The table below lists the differences
between the devices:
Test adapters
The OLS-3xV2 are delivered with SC adapters. Test adapters for
all common connector systems (e.g. FC, ST) can be ordered from
Viavi.

UNPACKING THE DEVICE
3 GETTING STARTED
3GETTING 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.
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
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.
WARNING
Dangers when handling batteries
Handling batteries may be dangerous. Please note the
following safety instructions.
JPlease note the battery operation safety information in the
section “Battery operation” on page 9.
Replacing the batteries
JDo not replace individual batteries. Always change both
batteries at the same time.
JAlways use batteries of the same type; i.e. do not mix
rechargeable and non-rechargeable batteries.

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.
