2Safety information

Before using the BERT 1005 product, ensure that the following safety information has been read and

understood.

Optical laser radiation precautions

Do not install or terminate fibers while the light source is active. Care must be taken to ensure

that the instrument has been turned OFF before inspecting the end face(s) of the instrument,

or any optical patch cords connected to this instrument. Never look directly into a live fiber;

ensure that your eyes are protected at all times.

The use of controls, adjustments, and procedures other than those specified herein may result

in exposure to hazardous situations involving optical radiation.

Electrostatic discharge precautions

The BERT 1005 product is sensitive to electrostatic discharge (ESD). Store the unused product in

the original protective electrostatic packaging that the product was shipped in.

Ensure that a wrist strap and grounding table mat is used when unpacking or handling the BERT 1005

product. Proper grounding and ESD management practices should always be followed to ensure that no

ESD damage is caused to the BERT product.

Electromagnetic compatibility

•For electromagnetic compatibility, this instrument is a Class A product. It is intended for use

in an industrial environment. There may be potential difficulties in ensuring electromagnetic

compatibility in other environments, due to conducted as well as radiated disturbances.

•Wherever the symbol is printed on the unit, refer to the instructions provided in the

device documentation for related safety information. Ensure that the required conditions

are met and understood before using the product.
