FCC Regulations:

zThis device complies with part 15 of the FCC 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 undesired operation.

zThis device 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 radiated 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.

Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s authority to operate the equipment.

zThis device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation.

zThe antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.

Appendix 2

Known Software Issue(s) in BlueTest Version 1.4

(a) Pressing the Reset Chip button on the GUI while data is being transmitted sends a

hardware reset command to the chip and restarts the serial stack software. Closing the GUI sends a hardware reset command to the chip. If the link fails, the connection can only be recreated by manually resetting the chip

(power off/on) and by clicking on Reset Chip or closing down and restarting the GUI (both of which will restart the serial stack software).

The above will not occur if no data is visibly scrolling in the window. The tests concerned are:

g VCOTRIM g BUILD LUT g READ g LUT

(b) There is a race between command responses indicatin g that a test has started and the

first data relating to that test. This does not affect the test results.

(c) It is not possible to rouse the chip from Deep Sleep except by powering down the chip

and restarting.
