Potential For Radio/Television Interference (for
U.S.A. Only)
The HP 12C Platinum generates and uses 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 and television reception. It has been
type tested and found to comply with the limits for a Class B 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 in
a residential installation. However, there is no guarantee that interference will
not occur in a particular installation. If your HP 12C Platinum does cause inter-
ference to radio or television reception, which can be determined by turning the
calculator off and on, you are encouraged to try to correct the interference by one
or more of the following measures:
z Reorient the receiving antenna.
z Relocate the calculator with respect to the receiver.
z Move the calculator away from the receiver.
If necessary, you should consult your dealer or an experienced radio/television
technician for additional suggestions. You may find the following booklet pre-
pared by the Federal Communications Commission helpful: How to Identify and
