This device is to be used only for mobile and fixed applications. The antenna(s) used for this
transmitter must be installed to provide a separation distance of at least 20cm from all persons
and must not be co-located or operating in 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 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. 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 technician for help
The host device shall also comply with the certification labeling requirements of each of the
modules it contains.
A reference to the enclosed module displaying its FCC and IC ID certification number.
Recommended wording:
* Contains FCC ID: W2Z-02000001
* Contains IC ID: 7736B-02000001
