Potential for Radio/Television Interference
(for U.S.A. Only)
The HP 82104A Card Reader generates and uses radio frequency
energy and, if not installed and used properly—that is, in strict
accordance with the instructions in this manual-——may cause inter-
ference to radio and television reception. It 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 installation. However, there is no
guarantee that interference will not occur in a particular installa-
tion. In the unlikely event that your card reader does cause inter-
ference to radio or television reception (which can be determined
by halting card reader operation) you are encouraged to try to cor-
rect the interference by one or more of the following measures:
* Reorient the receiving antenna.
* Relocate the HP-41 and the card reader with respect to the
receiver.
* Move the HP-41 and the card reader away from the receiver.
o If the HP-41 is being used with a rechargeable battery pack
that is plugged in, move the HP-41 and the card reader to a
different ac outlet so that the calculator and the receiver are
on different branch circuits.
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 Communica-
tions Commission, helpful: How to Identify and Resolve Radio-TV In-
terference Problems. This booklet is available from the U.S. Govern-
ment Printing Office, Washington, D.C. 20402, Stock Number 004-
000-00345-4.
