FCC INFORMATION
Attention users in the U.S.A.
PortaSound PSS-450 prepared in
accordance with FCC rules.
The PortaSound PSS-450 uses frequencies that appear in the
radio frequency range, and if installed in the immediate proximity
(within three meters) of some types of audio or video devices
interference may occur.
The PortaSound PSS-450 has been type tested and found to
comply with the specifications set for a Class B computing device
in accordance with those specifications listed in Subpart J of Part
15 of the FCC rules. These rules are designed to provide a
reasonable measure of protection against such interference.
However, this does not guarantee that interference will not occur.
If your PortaSound PSS-450 should be suspected of causing
interference with other electronic devices, verification can be
made by turning your PortaSound PSS-450 off and on. If the
interference continues when your PortaSound PSS-450 is off, the
PortaSound PSS-450 is not the source of the interference.
If your PortaSound PSS-450 does appear to be the source of the
interference, you should try to correct the situation by using one
or more of the following measures:
Relocate either the PortaSound PSS-450 or the electronic device
that is being affected by the interference.
Utilize power outlets for the PortaSound PSS-450 and the
device being affected that are on different branch (circuit breaker
or fuse) circuits, or install A/C line filters.
In the case of radio-TV interference, relocate the antenna or, if
the antenna lead-in is a 300 ohm ribbon lead, change the lead-in
to a co-axial type cable.
If these corrective measures do not produce satisfactory results,
please contact your Authorized Yamaha Specialty Products dealer
for suggestions and/or corrective measures. If you cannot locate
an Authorized Yamaha Specialty Products dealer in your general
area, contact the Specialty Products Service Center, Yamaha
International, 6600 Orangethorpe Ave., Buena Park, CA 90620.
If for any reason you should need additional information relating
to radio or TV interference, you may find a booklet prepared by
the Federal Communications Commission helpful; "How to Identify
and Resolve Radio-TV Interference Problems". This booklet is
available from the U.S. Government Printing Office, Washington
DC. 20402 - Stock # 004-000-345-4.
