Users Manual

1 When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock and injury, including the following: 1. Read and understand all instructions. 2. Follow all warnings and instructions marked on the product. 3. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. 4. Do not use this product near water (for example, near a bath tub, kitchen sink, or swimming pool). 5. Do not place this product on an unstable cart, stand, or table. The product may fall, causing serious damage to the product. 6. Slots and openings in the cabinet and the back or bottom are provided for ventilation. To protect it from overheating, these openings must not be blocked by placing the product on the bed, sofa, rug, or other similar surface. This product should never be placed near or over a radiator or heat register. This product should not be placed in a built-in installation where proper ventilation is not provided. 7. This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your dealer or local power company. 8. Do not allow anything to rest on the power cord. Do not locate this product where the cord will be abused by persons walking on it. 9. Never push objects of any kind into this product through cabinet slots as they may touch dangerous voltage points or short out parts that could result in a risk of fire or electric shock. Never spill liquid of any kind on the product. 10. To reduce the risk of electric shock, do not disassemble this product. Opening or removing cabinet parts other than specified access doors may expose you to dangerous voltages or other risks. Incorrect assembling can cause electric shock when the appliance is subsequently used. 11. Do not overload wall outlets and extension cords as this can result in the risk of fire or electric shock. 12. Unplug this product from the wall outlet and contact VTECH under the following conditions: A. When the power supply cord or plug is damaged or frayed. B. If liquid has been spilled into the product. C. If the product has been exposed to rain or water. D. If the product does not operate normally by following the operatinginstructions. Adjust only those controls that are covered by the operating instructions, because improper adjustment of other controls may result in damage and will often require extensive work to restore the product to normal operation. E. If the product has been dropped and the cabinet has been damaged. F. If the product exhibits a distinct change in performance. 13. Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning. 14. Do not use this or any cordless telephone to report a gas leak in the vicinity of the leak. Important Safety Instructions 2 VTECH COMMUNICATIONS INC. CUSTOMER SERVICE : 1-800-595-9511.

Users Manual

36 This equipment complies with Parts 15 of the Federal Communications Commission (FCC) rules for the United States. It also complies with regulations RSS210 and CS-03 of Industry and Science Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of thedevice. A label is located on the underside of the Base Unit containing either the FCC registration number and Ringer Equivalence Number (REN) or the IC registration number and Load Number. You must, upon request, provide this information to your local telephone company. This equipment is compatible with inductively coupled hearing aids. Should you experience trouble with this telephone equipment, please contact: VTech Communications Inc CUSTOMER SERVICE. at 1-800-595-9511. In Canada, call VTECH Electronics at 1-800- 267-7377. For repair/warranty information. The telephone company may ask you to disconnect this equipment from the line network until the problem has been corrected. FCC Part 15 Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The equipment has been tested and found to comply with 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 and correct the interference by oneor 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 or on a circuit different from that to which the receiver is connected. •Consult the dealer or an experienced radio/TV technician for help. FCC Part 68 and ACTA If this equipment was approved for connection to the telephone network prior to July 23, 2001, it complies with Part 68 of the Federal Communications Commission (FCC) rules. If the equipment was approved after that date, it complies with the Part 68 rules and with Technical Requirements for Connection of Equipment to the Telephone Network adopted by the Administrative Council for Terminal Attachments (ACTA). We are required to provide you with the following information. 1. Product identifier and REN information The label on the back or bottom of this equipment contains, among other things, an identifier indicating product approval and the Ringer Equivalence Number (REN). This information FCC, ACTA and IC Regulations Additional Information 37 must be provided to your local telephone company upon request. For equipment approved prior to July 23, 2001, the product identifier is preceded by the phrase “FCC Reg No.” and the REN is listed separately. For equipment approved after that date, the product identifier is preceded by “US” and a colon (:), and the REN is encoded in the product identifier without a decimal point as the sixth and seventh characters following the colon. For example, the product identifier US:AAAEQ03T123XYZ would indicate an REN of 0.3. The REN is used to determine how many devices you may connect to your telephone line and still have them ring when you are called. In most, but not all areas, the sum of all RENs should be five (5.0) or less. You may want to contact your local telephone company for more information. 2. Connection and use with the nationwide telephone network The plug and jack used to connect this equipment to the premises wiring and the telephone network must comply with the applicable Part 68 rules and technical requirements adopted by ACTA.

Output Power = 103 mW (20.1 dBm) (2) Page 43 -- Duty cycle = 10 x 850us / 100ms = 8.5% (measured in single slot transmission) Under the worst environment with interference, dual slot diversity gives the max. duty cycle on the handset Tx (ie. 8.5% x2 or 17%) Hence, taking the max. power output & max. duty cycle, the average effective output power is : 103 mW x 17% = 17.51 mW Conclusion : The average effective output power is lower than the 25mW (ie.60/freq.) threshold which starts to require SAR testing. Hence, there is no RF exposure concerns on handset. Base (Tx / Rx: 2.4GHz) Readings from test report : (1) Page 34 -- Max. Output Power = 115 mW (20.6 dBm) (2) Page 42 -- Duty Cycle = 40 x 800us / 100ms = 32% The phone is a TDD, FHSS. The testing was done at the worst case with 4 Tx carrier, equivalent to operating with 2 handsets in dual-slot diversity. Hence, taking the worst case, the average effective output power is : 115 mW x 32% = 37 mW Conclusion : The average effective output power is lower than the 50mW (ie.120/freq.) threshold which starts to require RF safety evaluation. Hence, there is no RF exposure concerns on base. Provided by : Joseph Poon Regulatory Compliance Manager VTech Engineering Canada Ltd.
