LS-200 Series
1. Introduction
The 200 Series Dual Light Source offers excellent stability and portability for accurate fiber optic testing. Single
output port provides stable laser power at dual wavelengths. The compact unit operates in either continuous wave
(CW) mode or modulated mode.
Designed with the technician in mind, output power is instantly adjustable from the keypad. A convenient “Low
Battery” indicator reminds the user to recharge the battery, while the lightweight, compact, ruggedized case of the
200 Series delivers rock-solid reliability under all working conditions.
2. Warranty
Three Years Limited Warranty
Products are warranted against the defective components and workmanship for a period of three years from the
date of delivery to the original customer. Any product found to be defective within the warranty period would be
returned to authorized service center for repair, replacement and calibration.
Exclusions
The warranty on your equipment shall not apply to defects resulting from the following:
Unauthorized repair or modification including battery replacement
Misuse
Negligence
Accident
Returning Product
To return product, you may contact PRO to obtain additional information if necessary. To serve you better, please
specify the reasons for the return. All delivery and mails should be sent to the following address:

3. Safety Information
Warning
Never look directly into optical outputs or a fiber while the equipment is on. Invisible and visible laser
beam may damage your eyes.
Do not short-circuit the terminal of AC adapter I charger and the batteries. Excessive electrical current
may cause personal injury due to fumes, electric shock or equipment damage.
Connect DC power cord with the equipment and wall socket properly. While inserting the DC plug, make
sure there is no dust or dirt on the terminals and both plugs are fully seated. Incomplete engagement may
cause fuming, electric shock or equipment damage and may result in personal injury.
Do not operate the equipment near hot objects, in hot environments, in dusty/ humid atmosphere or when
condensation is present on the equipment. This may result in electric shock, product malfunction or poor
performance.

4. Preparing for Operation
4.1 Unpacking the Instrument
Packing Material
We suggest that you keep the original packing material. Using the original packing material is your guarantee of
protecting the instrument during transit.
Standard Accessories:
Light Source, FC/PC, SC/PC, ST/PC Interchangeable Connector, User Manual, Worldwide-Compatible AC/DC
Power Adaptor, Rechargeable Ni-MH Batteries (x2), Test Report, Soft Carrying Case
Checking for Damage in Transit
After unpacking the instrument, check to see whether it was damaged in transit. This is particularly likely if the
outer casing is clearly damaged. If there is damage, do not attempt to operate the instrument or to repair it without
authorization. Doing so can cause further damage and you may lose your warranty qualification.
4.2 Power Supply
There are battery indicator and power plug on the screen to show the power supply. When you use the DC 6v
charger, there is no battery indicator on the screen. When you do not connect the DC 6v charger, the adapter
indicator will disappear on the screen.
When you use the battery, the battery indicator on the screen will show the remaining charge. An empty battery
indicator means the power is almost out. When the battery charge is extremely low to supply the necessary power,
the instrument will automatically switch off after several beeps of the buzzer. Please change the battery or
recharge it
