When correctly installed and maintained, the modem will present no
hazard to the user. When correctly installed the modem will be
connected to the PSTN or a PW and to a Data Terminal Equipment
(DTE), whose modem connections comply with ITU recommendation
V28. The DTE connections are therefore taken to be safe voltages (less
than ± 30 volts).

This equipment generates, uses, and can radiate radio frequency energy
and if not installed and used properly, that is, in strict accordance with
the manufacturer’s instructions, may cause interference to radio
communication. It has been tested and found to comply with the limits
for a Class A computing device in accordance with the specifications in
Subpart J of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference when the equipment is
operated in a commercial environment. 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
necessary to correct the interference.

Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate
the equipment.
