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.
