Product Name: ASUS WL-HDD2.5 Manual Revision: E1666 Release Date: May 2004 Preface ASUS 802.11g WL-HDD2.5iii Regulatory information Federal Communications Commission Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: • This device may not cause harmful interference; and • This device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to Part 15 of the Federal Communications Commission (FCC) rules. These limits are designed to provide reasonable protection against harmful interference in a residen- tial 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 encour- aged 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. WARNING! The use of a shielded-type power cord is required in order to meet FCC emis- sion limits and to prevent interference to the nearby radio and television reception. It is essen- tial that only the supplied power cord be used. Use only shielded cables to connect I/O devices to this equipment. You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.

Preface ivASUS 802.11g WL-HDD2.5 CE conformity statement The CE symbol indicates compliance of this equipment to the EMC Directive and the Low Voltage Directive of the European Union. These markings indicate that this system meets the following technical standards: EN 55022 — “Limits and Methods of Measurement of Radio Interference Characteristics of Information Technology Equipment.” EN 55024 — “Information technology equipment - Immunity characteristics - Limits and methods of measurement.” EN 61000-3-2 — “Electromagnetic compatibility (EMC) - Part 3: Limits - Section 2: Limits for harmonic current emissions (Equipment input current up to and including 16 A per phase).” EN 61000-3-3 — “Electromagnetic compatibility (EMC) -Part 3: Limits - Section 3: Limita- tion of voltage fluctuations and flicker in low-voltage supply systems for equipment with rated current up to and including 16 A.” EN 60950 — “Safety of Information Technology Equipment.” NOTE: EN 55022 emissions requirements provide for two classifications: • Class A is for typical commercial areas. • Class B is for typical domestic areas. To determine which classification applies to your computer, examine the CE registration label located on the back panel of the device. If the label indicates a Class A rating, the fol- lowing warning applies to your device: RF INTERFERENCE WARNING: This is a Class A product. In a domestic environment this product may cause radio frequency (RF) interference, in which case the user may be required to take adequate measures. This device is classified for use in a typical Class A …

Measurement of Maximum Permissible Exposure －－－－－－－－－－－－－－ 1/3 Applicant: ASUSTeK Computer Inc. FCC ID: MSQWLHDD25 Training Research Co., Ltd., TEL: 886-2-26935155, Fax: 886-2-26934440 Measurement of Maximum Permissible Exposure 1. Foreword In adopt with the Human Exposure IEEE C95.1, and according to the FCC 1.1310. The Maximum Permissible Exposure (MPE) is obligated to measure in order to prove the safety of radiation harmfulness to the human body. The Gain of the antenna used is measured in an Anechoic chamber. The maximum total power to the antenna is to be recorded. By adopting the Friis Transmission Formula and the power gain of the antenna, we can find the distance right away from the product, where the limit of the MPE is. 2.
