FCC Class A Notice

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.  Front Panel Operation is subject to the following two conditions: (1) this device 

may not cause harmful interference, and (2) this device must accept any interference received, including 

interference that may cause undesired operation.  The Class A 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.  Front 

Panel 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.

N

  This unit was tested with shielded cables on the peripheral devices.  Shielded cables must be used with the 

unit to ensure compliance with FCC emissions limits.
