ELECTOROMAGNETIC COMPATIBILITY INFORMATION
WARNING
• Portable RF communications equipment should be used no closer than 30 cm (12
inches) to any part of the [CH-453], including cables specied.
• Use of this equipment adjacent to or stacked with other equipment should be avoided.
• Use of accessories and options other than those specied (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-453] is intended for use in the electromagnetic environment specied below. The
customer or the user of the [CH-453] should assure that it is used in such an environment.

RF emissions
CISPR 11
Group 1 The [CH-453] 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.

establishments and those directly connected to
the public low-voltage power supply network that
supplies buildings used for domestic purposes.
