Radio frequency interference
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations. This device complies with Part 15 of the FCC Rules. 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.
Warning
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
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 their own expense. Shielded cables must be used with this unit to ensure
compliance with the Class A FCC limits. Because this instrument operates on and
generates radio frequency energy, interference to radio and television reception may occur.
If such interference does occur, the operator should take the necessary steps to correct the
interference. The following techniques of reducing the interference problems are easily
applied:
• Disconnect power from the BODTrak II instrument to verify the instrument is
the source of the interference.
• If the BODTrak II is plugged into the same outlet as the device with which it is
interfering, try another outlet.
• Move the BODTrak II away from the device receiving the interference.
• Reposition the receiving antenna for the device receiving the interference.
• Try combinations of the above.
