ELECTOROMAGNETIC COMPATIBILITY INFORMATION
Appendix
The use of accessories and cables other than those speci
fi
ed (other than CITIZEN
original parts) may result in increased emissions or decreased immunity of the unit.
Guidance and manufacturer’s declaration - electromagnetic emissions
The [CHU305] is intended for use in the electromagnetic environment speci
fi
ed below. The
customer or the user of the [CHU305] should assure that it is used in such an environment.

RF emissions
CISPR 11
Group 1
The [CHU305] uses RF energy only for its internal
function. Therefore, its RF emissions are very
low and are not likely to cause any interference in
nearby electronic equipment.
RF emissions

Class B
The [CHU305] is suitable for use in
all establishments, including domestic
establishments and those directly connected to
the public low-voltage power supply network that
supplies buildings used for domestic purposes.
