FCC Regulations
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, can 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 is required to correct the interference at his own expense.
Modifications to the laser system not expressly approved by Spectra-Physics could void
the user’s right to operate the equipment.
