The PortaTone PSR-36 uses frequencies that appear in the
radio frequency range, and it installed in the immediate
proximity (within three meters) of some types of audio or
video devices interference may occur.
The PortaTone PSR-36 has been type tested and tested
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 PortaTone PSR-36
should be suspected of causing interference with other
electronic devices, verification can be made by tuning your
PortaTone PSR-36 off and on. If the interference continues
when your PortaTone PSR-36 is off, PortaTone PSR-36 is not
the
source of the interference. If your PortaTone PSR-36
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 PortaTone PSR-36 or the electronic
device that is being affected by the interference.
Utilize power outlets for the PortaTone PSR-36 and the
device being affected that are on different branch ( circuit
breaker of 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 dealer for
