-Caution
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate this device.
This device complies with Part 15 of the FCC`s Rules. Operation is subject to the following two Conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesirable operation.
This device 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 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 technical for help.
This device complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This device should be installed and operated with minimum distance 20cm between the radiating element of this
device and the user.
This device must not be co-located or operating in conjunction with any other antenna or transmitter.
This device may only operate using an antenna of a type and maximum (or lesser) gain approved by partron.
Antenna types not included in the list, having a gain greater than the maximum gain indicated for that type, are
strictly prohibited for use with this transmitter.
