Safety Information

WARNING

Electromagnetic compatibility

This product is a CISPR 11 Group 1 Class A compliant device. This product may cause

interference if used in residential areas. Such use must be avoided unless the user takes special

measures to reduce electromagnetic emissions to prevent interference to the reception of radio

and television broadcasts.

●Safety symbols

Caution, refer to instruction manual

This notifies the user of potential hazards and indicates that he/she must refer to the

instruction manual.

Caution, possibility of electric shock

This indicates that an electric shock may occur under specific conditions.

Protective earth ground terminal

This indicates that the terminal needs to be grounded in order to prevent electric shock

accidents.

Before operating the product, ensure to connect this terminal to an earth ground.

Warning

This contains information to avoid risks in equipment handling that could

result in loss of life or bodily injury.

Caution

This contains information to avoid risks in equipment handling that could

result in minor or moderate injury to person or damage to property or the

equipment.

●Other symbols

This indicates that the terminal or the outer conductor of the connector is connected to

the enclosure.

This indicates that the terminal or the outer conductor of the connector is connected to

the signal ground.

This indicates that the terminal or the outer conductor of the connector is isolated from

the enclosure.

It indicates, however, that the difference of the potential from the ground potential is

restricted to 42 Vpk or less for safety (this product is used grounded so the enclosure

potential and ground potential are equal).

Waste disposal

For environmental protection, do not discard this product in domestic household waste. This

product shall be disposed of through an appropriate industrial waste disposer.
