Safety Information
To avoid personal injury or the product and other products connected with
being damaged, you should be careful of the safety information. Make sure use
the product according to the rules to prevent the occurrence of some potential
harm.
Attention:
1. Power Voltage. The device can be only used in the area where the power is
AC 220V±20％/50Hz. Please don’t use in other areas.
2. Use proper power line and power. You must use the power line equipped
with the products randomly. Also you can use other qualified power line
with case which can protect earth terminal. The earth terminal of the outlet
that is matched with power cord should be well ground connection.
3. Attention ground connection. The product is grounded by the conductor in
the power line or terminal on the panel. To avoid electric shock, the ground
conductor of the power line must be grounded in a good connection with
the earth. Before you connect all the optical ports of the product, you

should be sure that the product is well grounded.
4. Take care of typical value of the ports. To avoid fire or electric shock, please
pay attention to all typical values and symbols labeled in the equipment and
this manual.
5. Don’t venture operation. When you doubt this product cannot work
properly, please consult our professionals instead of venturing operation.
6. Vibrations and Crash. This machine contains elaborate optical component,
you should avoid strenuous vibrations and crash.
7. Don’t open the cover of the machine and repair arbitrarily. There aren’t
components for users to repair in the main case of this product. If you need
repair the product, please contact our company professionals. As soon as
you open the cover, you will have no warranty.

Cautions
1. The product is Class IIIB laser device product. There is the laser radiation
that your eyes cannot see in the machine. It is possible that the machine will
cause some physical damage of your eyes and skin if you operate it
improperly. After the machine powers up, you can’t look steadily at the
fiber optical input and output port or the fiber connector interface
connected with the ports.
2. Keep the fiber optical connector clean, or it will cause attenuation and affect
transmitting distance. When you install the product, you should dip tidy
cotton with absolute ethyl alcohol to clean it.
3. The product is sensitive to static electricity. Before you contact with electric
interface, you should release static electricity.
4. To prevent fire or electric shock, please don't let the product wet or damp.
Don't operate in damp conditions.
5. Don’t open the lid of the product to operate it.
6. Keep the surface clean and dry. You should ensure good ventilation and
heat-emission.
