GUIDE TO INSTALLATION AND OPERATION 
 

HCO-1822 
 

Electromagnetic Compatibility 

 

This equipment has been tested for verification of compliance with FCC Part 15, Subpart B requirements for 

Class A digital devices. 

NOTE:

 This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to 

part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference 

when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate 

radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful 

interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful 

interference in which case the user will be required to correct the interference at his own expense. 

 

 

This equipment has been tested and found to comply with the requirements of the EMC directive 

2004/108/CE: 

 

EN 55022 Class A radiated and conducted emissions 

 

ENV 50204 Radiated EMF Immunity – RF 900 MHz Pulsed 

 

EN 61000-3-2 Harmonic current emission limits 

 

EN 61000-3-3 Voltage fluctuations and flicker limitations 

 

EN 61000-4-2 Electrostatic discharge immunity 

 

EN 61000-4-3 Radiated electromagnetic field immunity – radio frequencies 

 

EN 61000-4-4 Electrical fast transient immunity 

 

EN 61000-4-5 Surge transient immunity 

 

EN 61000-4-6 Conducted disturbances immunity
