ence to radio communications. However,
there is no guarantee that interference will
not occur in a particular installation. If
this equipment does cause harmful inter-
ference to radio or television reception,
which can be determined by turning the
equipment off and on, the user is encour-
aged to try to correct the interference by
one or more of the following measures:
1. Reorient or relocate the receiving
antenna.
2. Increase the separation between the
equipment and receiver.
3. Connect the equipment into an out-
let on a circuit different from that
to which the receiver is connected.
4. Consult the dealer or an experience
radio/TV technician for help.
