ENVIRONMENTAL QUALIFICATION FORM,TSO-C58A
INFORMATION TO USERS ———————————————————————
This equipment has been tested and found to comply with the
limits for a Class B digital device pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency ener-
gy, and, if not installed and used in accordance with the instruc-
tions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equip-
ment off and on, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the microphone and receiver.
•
Connect the microphone transmitter into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for
help.
