21-92955 Integration Guide Copyright 2004 Symbol Technologies, Inc. Page 6 of 11 2.3 Electrical Interface The electrical interface for the module is SDIO. The chipset used supports this interface; therefore no external component is required. The host must support the SDIO interface as well. 3. Regulatory Product Compliance Legal Disclaimer: This Guide may contain information on regulatory matters. The information should be used with the understanding that Symbol is not engaged in rendering any legal, regulatory or other professional opinion. Each country has specific laws and regulations governing the use of radio communications. Please consult the official code for each country of interest. Symbol does not warrant the accuracy of the information contained herein and accepts no liability or responsibility for any use or misuse of the information Symbol’s wireless network devices are designed to be compliant with rules and regulations in locations they are sold. Any changes or modifications to Symbol Technologies equipment, not expressly approved by Symbol Technologies, could void the user’s authority to operate the equipment. IMPORTANT NOTE: End product user guide must NOT include any information regarding how to install or remove this RF module. 3.1 Final Product Compliance The model Number used for Regulatory Approvals is: 21-92955 The module has been regulatory approved for integrations which meet the following conditions: 1. The radio integration is embedded 2. The antenna must be installed such that 20 cm is maintained between the antenna and users
21-92955 Integration Guide Copyright 2004 Symbol Technologies, Inc. Page 7 of 11 3. The ‘Type’ and ‘Gain’ of the antenna selected for the integration of the external antenna must meet the requirements as detailed in section. Used outside of these conditions will trigger re-approval As the integrator, you are responsible to determine what additional specific regulatory requirements are required of the country in which your product will be marketed. Final product may require non-radio frequency approvals such as Product Safety, EMC, and SAR. 3.2 Reference Antenna A reference antenna has been used during the approval process. Specific details of the reference antenna used for testing is detailed in the table below. Important Note: Use of an antenna which is the same ‘type’ (eg. Dipole) and has a gain equal to or less that the reference antenna can be used without recertification. Use of an alternative antenna, different ‘type’ or same ‘type’ but higher gain will invalidate the country approvals. Under this instant the integrator is responsible for re-evaluating the end product and obtaining separate approvals. Antenna Type: Dipole Antenna Characteristics: ML-2452-APA2-01

Radio Frequency Interference Requirements – FCC 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. Radio Transmitters (Part 15) This 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.
