ELECTOROMAGNETIC COMPATIBILITY INFORMATION
WARNING
• Portable RF communications equipment should be used no closer than 30 cm (12
inches) to any part of the [CH-452-AC], including cables specified.
• Use of this equipment adjacent to or stacked with other equipment should be
avoided.
• Use of accessories and options other than those specified (other than CITIZEN
original parts) could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment.
Guidance and manufacturer's declaration - electromagnetic emissions
The [CH-452-AC] is intended for use in the electromagnetic environment specified below. The
customer or the user of the [CH-452-AC] should assure that it is used in such an environment.

Electromagnetic environment - guidance
The [CH-452-AC] 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.
The [CH-452-AC] 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.
Electromagnetic environment -
guidance
Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humidity
should be at least 30%.
Mains power quality should be that of a
typical commercial or hospital
environment.
Mains power quality should be that of a
typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
[CH-452-AC] requires continued
operation during power mains
interruptions, it is recommended that
the [CH-452-AC] be powered from
an uninterruptible power supply or a
battery.
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or
hospital environment.
