ELECTOROMAGNETIC COMPATIBILITY INFORMATION
WARNING
• Portable RF communications equipment should be used no closer than 30 cm (12
inches) to any part of the [CHUD514/517], 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 [CHUD514/517] is intended for use in the electromagnetic environment specied below. The
customer or the user of the [CHUD514/517] should assure that it is used in such an environment.

Group 1 The [CHUD514/517] 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.
