INFORMATION TO THE USER
The EC4 Receiver complies with Part 15 of the FCC Rules. Operation is
subject to the condition that this device does not cause harmful interference.
The EC4 Receiver has been tested and found to comply with the lim-
its of Part 15 of the FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference in a residential installa-
tion. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular instal-
lation. If this equipment does cause harmful interference to radio or tele-
vision reception, which can be determined by turning the equipment off
and on, the user is encouraged 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 radio or TV re-
ceiver.
(3) Connect the equipment into an outlet on a circuit different from that to
which the radio or TV receiver is connected.
(4) Consult the dealer or an experienced radio/TV technician for help.
CAUTION: Changes or modifications not expressly approved by Shure
Brothers, Inc. could void your authority to operate the equipment.
