These two parameters are the most important for antenna performance. Reserve space around the antenna as much as possible. Connect all parts as close as possible to the pins of module and reduce the length of routing traces, to help on good audio performance, proper antenna pattern and EMC. When designing the receiver module in wireless speakers and headphones, the important design considerations are as follows: 1. Keep metal objects away from the antenna by 3 cm distance at least to avoid degradation on the antenna. For example, speaker unit, transformer, adaptor, wire, cable and other big metal object beside antenna will degrade the antenna performance. 2. Use regulated DC-power-supply to the modules, and separate the DC-power-supply of module with the other circuits. Antenna 1. Wire Antenna: A 27~31mm plastic-covered wire can be used as antenna. In principle, 31mm length is for a wire without any cover or very thin cover. The thicker of the cover, the shorter of the antenna length. Try various length for a certain wire to optimize the transmission distance. 2. Antenna Soldering: Page 5 of 7 2007.12.06 Version: 1.0 www.elansat.com DRF-TR001 Wireless Digital Transceiver ELANsat Operation Block Diagram of DRF-TR001 The SPI data then is fed to SOIC for encoding, FSK-modulation, frequency conversion, and amplification. RF signal between SOIC and antenna is separated to two paths: transmission and receiving (by two RF switches). Transmitted RF Signal from SOIC is following by a power amplifier to increase output power and transmission distance.

Page 6 of 7 2007.12.06 Version: 1.0 www.elansat.com DRF-TR001 Wireless Digital Transceiver ELANsat This device complies with Part 15 of FCC Rules and RSS-Gen of IC 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. Note: This equipment contains module, FCC ID: UDRX0738CSF and IC: 0976B-D0738CSF, which qualifies as an UNLICENSED MODULAR TRANSMITTER per FCC Public Notice DA 00-1407 and RSS-Gen Section: 7.1.1. It has been tested and found to comply with Part 15.249 of the FCC Rules and RSS-210 issue 7:2007, Annex 2.9. Required labeling. Any device incorporating this module must include an external, visible, permanent marking or label which states: “Contains FCC ID: UDRX0738CSF” “Contains IC: 0976B-D0738CSF” Failure to comply with this requirement will void the user’s authority to operate any device that incorporates this module. This equipment complies with FCC/IC radiation exposure limits set forth for uncontrolled equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment has very low levels of RF energy that it is deemed to comply without testing of specific absorption ratio (SAR). To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.
