Users Manual

Test Report No.: NK2GR003 CMOTech Co., Ltd. FCC ID :TARCDU-550 Page 76 of 78 Appendix F – USER’S Manual CDU-550 Modem User Guide FCC RF EXPOSURE COMPLIANCE In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of this modem complies with the FCC guidelines and these international standards. Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the modem, or result in violation of FCC regulations. This CDMA 1xEVDO USB data modem has been tested for FCC RF exposure hand and body SAR compliance with the CDU-550 USB dongle modem form factor. In order to comply with FCC RF exposure requirements, the CDMA 1xEVDO USB data modem must be operated with the CDU-550 USB dongle modem form factor. The use of this device in any other type of host configuration may not comply with FCC RF exposure requirements and should be avoided. During operation, a 1.5cm separation distance should be maintained between the antenna, whether extended or retracted, and the user’s/bystander’s body (excluding hands, wrists, feet, and ankles) to ensure FCC RF exposure compliance. CAUTION Change or modification to the modem without the express consent of Data Poz Co., Ltd. voids the user’s authority to use the equipment. This equipment has been tested and found to comply with the limits pursuant to Part 22 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. ■ Consult the dealer or an experienced Radio / TV technician for help. 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 communication. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful unacceptable interference to 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. ■ Consult the dealer or an experienced Radio/TV technician for help. Cautions for Users -Use of CDU-500 EV-DO Modem (hereinafter referred as modem ), while running a notebook PC with a battery, may cause earlier exhaustion of the battery than usual due to additional consumption of electric currents. -Be cautious when you touch a modem with a bare hand after long use, it may cause a burn due to its high temperature. Pick it out with the antenna after separation. -Do not allow children or pets to approach or touch the modem when separated from a notebook PC or PDA. -Do not give impact to the modem or throw it away. -Use the leather case provided along with the modem when you carry the modem. -When the modem is lost or stolen, immediately report it to the corresponding telecommunication operator. -Do not recklessly lend your own modem to anybody else. -Call to a service center designated by CMOTech for after-sales service. -Do not attach an additional device which may cause alteration in performance of the product registered for the type approval. -This modem sends and receives the radiofrequency (RF) energy in status of power-on. The radiofrequency (RF) energy may affect a human body. -Use an antenna only approved by CMOTech. Otherwise it may cause a damage on the modem and you will not get a free after-sales service. -Use the modem in the manner you use a notebook PC in general. -Make the antenna stand and do not touch it when being used. If the antenna is touched, the quality of transmission and reception may be lowered and it will cause excessive power consumption. -Be cautious as the radiofrequency (RF) energy may affect the electronic devices installed in a car. -Be noticed that most of electronic devices are designed to be free from the RF energy but there are some products that may be out of order due to the RF energy. -Medical Devices Industry Association recommends the patients using a pacemaker not to use RF using devices such as cell phones, wireless modems and so on because using those devices in the range of 15cm from the pacemaker may affect the pacemaker. In an inevitable situation, make it sure to keep the distance of more than 15cm between the modem and the pacemaker. To minimize the possible interference, use the modem on the opposite side of the pacema…

Grant Notes

Power listed is EIRP for Part 24 and ERP for Part 22. SAR compliance has been established in three laptop computer configurations with PCMCIA slots on the side or rear as tested in this filing; and can be used in laptop computer(s) with similar physical dimensions, construction, and electrical and RF characteristics. Compliance of this device in all final host configurations is the responsibility of the Grantee. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter and must provide at least 1.5 cm separation between the device, including its antenna, and the user's body. End-users must be provided with specific information required to satisfy RF exposure compliance for all final host devices. The highest reported SAR values are: Part 22 - Body: 1.19 and Part 24 - Body: 0.90 W/kg.
