conjunction with any other antenna or transmitter.
NOTE:
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 CERTIFICATION
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 energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. 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
equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following
MEASURES:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and
receiver.
- Connect the equipment 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.

Tips and Methods to Improve Wireless System
Performance
1) keep Receiver away with each transmitter and more
than 3 meters from routers.
2) Change channels to avoid interference with other WiFi
products.
3) Environmental interference in multiple wireless
systems,Please shorten the distance between the
transmitter and the receiver.
