Safety and Regulatory Information
For your protection, the HP-18C has been tested to various national
and international regulatory standards. This regulatory testing in-
cludes electrical/mechanical safely, radio interference, ergonomics,
acoustics, and hazardous materials. Where required, approvals ob-
tained from third-party test agencies are shown on the product label.
In addition, various regulatory bodies require some of the information
under the following headings:
U.S.A. Radio Frequency Interference
The HP-18C generates and uses radio frequency energy and may
cause interference to radio and television reception. Although the
HP-18C has been 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 instal-
lation, there is no guarantee that interference will not occur in a
particular installation. In the unlikely event that there is interference
to radio or television reception (which can be determined by turning
the HP-18C off and on or by removing the batteries), you are encour-
aged to correct the interference by one or more of the following
measures:
• Reorient the receiving antenna .
• Relocate the product with respect to the receiver.
If necessary, you should consult your dealer or an experienced
radio/television technician for additional suggestions. You may find
the following booklet, prepared by the Federal Communications Com-
mission, helpful:
How to Identify and Resolve Radio-TV Interferen ce
Problems.
