Regulatory Information
Radio Frequency Interference
U.S.A. The HP-22S generates and uses radio frequency energy and
may interfere with radio and television reception. The calculator com-
plies with the limits for a Class B computing device as specified in
Subpart ] of Part 15 of FCC Rules, which provide reasonable protec-
tion against such interference in a residential installation. In the
unlikely event that there is interference to radio or television reception
(which can be determined by turning the HP-22S off and on or by
removing the batteries), try:
B Reorienting the receiving antenna.
B Relocating the calculator with respect to the receiver.
For more information, consult your dealer, an experienced
radio/television technician, or the following booklet, prepared by the
Federal Communications Commission: How to Identify and Resolve Ra-
dio-TV Interference Problems. This booklet is available from the U.S.
