ELECTOROMAGNETIC COMPATIBILITY INFORMATION
WARNING
• Portable RF communications equipment should be used no closer than 30 cm (12
inches) to any part of the [CHU304/305], 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.

Compliance Electromagnetic environment - guidance
Group 1 The [CHU304/305] 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.
Class B The [CHU304/305] is suitable for use in
all establishments, including domestic
establishments and those directly connected to
N/A
the public low-voltage power supply network that
supplies buildings used for domestic purposes.
