Operating Guidelines for MAHB Series Handheld Portable Transmitters • Button Press LED – Window should light when a button is pressed. If it does not, you may need new batteries. • 3 AAA batteries are required to operate the device. See back of remote. • If range of transmission decreases, replace batteries. • Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 in-stalled 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.

We have requested that the Block Diagrams, Schematics & Theory of Operations required to be submitted with this application be withheld from public review. The documentation listed in the report may divulge sensitive information about our product to our competitors. Please contact me if there is any information you may need. Sincerely, Patrick S. Ferguson

Chris, Please see responses below: 1. The Confidentiality letter requests that the entire application be held confidential, which is not allowed per FCC rules. The letter must reference both 0.459 and 0.457 and specify the exact exhibits that are being requested for confidentiality of the exhibits that the FCC allows to be held confidential. Revised. Please see file: Confidentiality_Rev2.pdf 2. The report does not indicate that the orientation of this hand-held transmitter was changed between x, y, and z for measurements and the photos only show unit flat on table. Please ensure that this device was measured in all 3 orthogonal axis and update the report accordingly. All three axis measurements were performed. During the maximization, we alternate the antenna polarization with the combination of the rotation of turn table. So laying flat on the table has covered both X & Y axis. Then I put the EUT in vertical position and tested with the same procedure which covers my Z axis orientation. We found that laying flat on the table with the combination of horizontal polarity of receive antenna are the worst case and only the worst case was put on the report. 3. The schematic shows a wired interface option and the photos show a connector on the PCB. If this transmitter has the ability to transmit the RF signal when the optional cable is attached, was this investigated during the compliance testing to determine worst case emissions? The enclosure was sealed and provides no external access to user. Attachments are the picture of the enclosure seams along all 4 sides which illustrate the integrality of the unit. From the front, looks like you can open a cover and get access to the board. I have included an inner picture to show that it is not accessible. 4. The Duty-Cycle calculation on page 16 of 39 in the test report incorrectly uses the Tx-off time in the denominator instead of using the full Pulse duration in the denominator. A 33.85% Duty Cycle would calculate to -9.4dB, not -5.82dB. There are also typos in the units used in all the field-strength limits in the table (should be uV/m & dBuV/m @ 3 meters). It appears as though the measure data was not corrected for the Duty-Cycle factor. The rows for measurement data indicate average or peak, but the column for uncorrected data indicates the use of a QP detector. Was a QP detector used? Was the duty cycle correction factor used? Please update the report to clarify these points. All data have been applied with duty cycle correction factor. The measurements were performed in Peak and Average mode. QP detector was not used.

The Confidentiality letter requests that the entire application be held confidential, which is not allowed per FCC rules. The letter must reference both 0.459 and 0.457 and specify the exact exhibits that are being requested for confidentiality of the exhibits that the FCC allows to be held confidential. 2.

Please update the report to clarify these points. 5. The test report contains blank sections for Exhibit A, Hopping Capability Requirement and Exhibit B, Non-Coordination Requirement which do not appear to be applicable to a 15.231 device. Please provide a single comprehensive response, but feel free to ask questions if needed. Best regards, Chris Harvey Page 2 of 2 4/30/2007

The MAHB has an antenna integrated into the PCB as shown in the following picture: The amplification is done by a transistor similar to the one at the end of this document (Schematic Designator Q2) The frequency source is provided by a SAW Resonator (Schematic Designator T1). A datasheet for a similar component is attached at the end of this document. The modulation scheme is ASK of inverted serial data directly from a microcontroller (Schematic Designator U1). The baud generated from the UART in the microprocessor is 2400. This inverted signal is fed directly to the SAW resonator so the device transmits when the serial line from the micro processor is low and is not transmitting when the serial line is high (off). Inversion performed by Schematic Designator Q4.
