Electromagnetic Radiation Notice
The following information is given to note compliance with the United States Government Federal Communications
Commission (FCC) Rules (47 CFR Part 15) designed to limit interference to radio and TV reception. The ruling establishes
measurement procedures and frequency criteria for Class A computing devices (commercial and industrial applications) with
the following conduction and radiation limits:
CLASS A COMPUTING DEVICE: CONDUCTION LIMIT (Part 15.812)
Frequency (MHz)
Maximum RF Line Voltage (uV)
0.45 - 1.6
1000
1.6 - 30
3000
CLASS A COMPUTING DEVICE: RADIATION LIMIT (Section 15.810)
Frequency (MHz)
Distance (meters)
Field Strength (uV/m)
30 - 88
30
30
88 - 216

The policy of Thomson is one of continual development and improvement. For that reason Thomson uses components and
manufacturing techniques that provide the current state-of-the-art suppression of electromagnetic radiation. This equipment, in
production before October 1, 1981, has not been tested to the above listed measurements. However, equipment such as this
delivered after October 1, 1983 will have the measurements on record at the factory. Therefore, in compliance with the stated
FCC Regulation, the following information is provided for the user:
NOTE
Interference to Radio Communications
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used
in accordance with the instruction manual, may cause interference to radio communications. As
temporarily permitted by regulation it has not been tested for compliance with the limits for Class A
computing devices pursuant to Subpart J of of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference.
Operation of this equipment in a residential area
is likely to cause interference
in which case the user at his own expense will be required to take
whatever measures may be required to correct the interference.
