WLN150x Wi-Fi Adapter iii Safety Information for Wireless Handheld Devices The equipment certifications appropriate to your device are marked on the device and product specific information. The use of the equipment is subject to the following conditions: FCC COMPLIANCE STATEMENT This device complies with the limits for a Class B digital device, pursuant to 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. CAUTION Changes or modifications without the express consent of Enfora, Inc. void the user’s authority to use the equipment. 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 an appropriate installation. This equipment generates, uses, and can radiate radio frequency energy and, if not used in accordance with instructions, can cause harmful radiation to radio communication. However, there is no guarantee that interference will not occur in a particular installation. If the equipment does cause harmful interference in radio and television reception, which can be determined by turning the equipment on and off, 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 distance between the equipment and the receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Contact Enfora, Inc. Technical Support for assistance. FCC Radiation Exposure Statement 1. CAUTION: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. 2. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The Federal Communications Commission (FCC) with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. Enfora products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991.Proper operation of this radio according to the instructions found in this manual and the hardware and software guides on the CD will result in user exposure that is substantially below the FCC recommended limits.

August 31, 2005 To Whom It May Concern: Enfora Inc. would like to apply for Limited Modular FCC approval. This letter is our request for such according to FCC public notice DA 00-1407. Limited Modular Transmitter Requirements Modular Transmitter Requirements Manufacturer Clarification A – In order to be considered a transmitter module, the device must be a complete RF transmitter, i.e., it must have its own reference oscillator (e.g., VCO), antenna, etc. The only connectors to the module, if any, may be the power supply and modulation/data inputs. The transmitter is complete with its own reference oscillator, antenna, and voltage regulation.. The only connectors provided are the DC Supply and Data. B – Compliance with FCC RF Exposure requirements may, in some instances, limit the output power of a module and/or the final applications in which the approved module may be employed. The radio complies with MPE per 2.1091 for use as a portable device. C – While the applicant for a device into which an authorized module is installed is not required to obtain a new authorization for the module, this does not preclude the possibility that some other form of authorization or testing may be required for the device (e.g., a WLAN into which an authorized module is installed must still be authorized as a PC peripheral, subject to the appropriate equipment authorization). The equipment complies with FCC Part 15, Subpart B, Class B – Unintentional radiators. The device with which the module is intended to operate holds a certification as a licensed device. D – In the case of a modular transceiver, the modular approval policy only applies to the transmitter portion of such devices. Pursuant to Section 15.101(b), the receiver portion will either be subject to Verification, or it will not be subject to any authorization requirements (unless it is a Scanning Receiver, in which case it is also subject to Certification, pursuant to Section 15.101(a)). The receiver operates in 2412 – 2462 MHz band. Modular Transmitter Requirements Manufacturer Clarification E – The holder of the grant of equipment authorization (Grantee) of the module is responsible for the compliance of the module in its final configuration, provided that the OEM, integrator, and/or end user has complied with all of the instructions provided by the Grantee which indicate installation and/or operating conditions necessary for compliance. End users must conform with the following instructions stated in the users’ manual: - Labeling requirement for equipment using this modular transmitter. - RF Exposure information for compliance with FCC Rules 2.1091 or 2.1093 are specified in the user manual for OEM, integrator, and/or end user. 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits... Such coupling may result in non-compliant operation. The modular transmitter has its own RF shielding. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The modular transmitter has buffered modulation/data inputs. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. The modular transmitter has its own power supply regulation. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204c. The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module; either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules. The radio complies with Rules 15.203 and 15.204c. The antenna is integral to the module. Modular Transmitter Requirements Manufacturer Clarification 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed... The modular transmitter was tested in a stand-alone configuration. 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module... The modular transmitter is labeled with its own FCC ID number. The label is fixed on the plastic housing of the modular device. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. The user manual contains adequate instructions relating to the usage, approved antennas, and power supply requirements of the modular transmitter. 8. The modular transmitter must comply with any applicable RF exposure requirements. The modular transmitter is exempt from a routine SAR evaluation due to the fact that the rf output power is 9 mW conducted (14.5 mW eirp).
