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 reassemb-ling 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. Important Safety Instructions 2 12.Unplug this product from the wall outlet and refer servicing to 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 operating instructions. 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.

Correspondence Reference Number: 23088 731 Confirmation Number: EA528508 Subject: SAR Dear Mr. Leimer, Pursuant to your e-mail with the above reference, we are forwarding to you our responses to your questions as quoted below. 1) SAR report pg 12 lists target body rel. permitt. = 35.3 conductivity = 5.27. These are Suppl C head values; body is 48.2 and 6 respectively. Please provide estimate of change in SAR for correct body parameters using Kuster/Balzano theory, FDTD modeling, re-test, or similar. Response: The tissue used by APREL laboratories was developed internally so as to fulfill the obligation of SAR testing at 5.8 GHz. Two tissues have been developed, one for body and one for head. The tissue used was that developed for body and the appropriate values have been inserted into the table below. The engineer mistakenly inserted the wrong data for the tissue. Body TissueAPRELTarget Value ∆∆ (%) Dielectric Constant εεr 46.148.24 Conductivity, σσ [S/m] 6.906.015 Tissue Conversion Factor2.5-- The sigma value measured exceeds the 10% margin by 5%. However the uncertainty associated with the dielectric set-up has in some cases a 10% uncertainty attributable to the values recorded, (IEEE). APREL laboratories measured the tissue over a period of one day where the values were recorded to assess uncertainty attributable to the value measured using the APREL set-up. Over the period of the measurements being taken the highest recorded sigma 6.90 , was what has been used in respect to the body tissue used for the assessment. The epsilon recorded was generally repeatable to within 2% of the measured value over the period. In respect to the assessed SAR measured with the tissue parameters as they appear in the above table, APREL can stand behind the statement that the recorded SAR values of 1.22 W/kg for direct contact SAR, and 1.18 W/kg body SAR are conservative, and if scaling was used the recorded Conservative SAR values would be reduced due to the higher value of sigma being used. An adjustment to the uncertainty table for Appendix D, attributable to the experimental measurements has now been made and the table below represents the adjusted values.

Response:The dipole target values were devised by using the existing target values contained in the IEEE P-1528 Standard and creating a trend for which the SAR would follow. From this an extrapolation formulae was used and the values calculated for Peak, 1 gram, and 10 gram SAR. Once the SAR values were calculated a ¼ wavelength dipole was then theoretically created. This experiment provided the physical dimensions for the length across the whiskers and the balun. The dipole was then manufactured and tuned specifically to the tissue, for return loss, and matched to 50Ω. The calculated target values were then used to gauge the measured SAR for the dipole while the dipole was being fed with a power of 100 mW, and the final SAR value was scaled accordingly. We trust that the above will answer questions. Please feel free to contact as appropriate if you have any question.

The measurements were carried out in accordance with FCC 96-326. The VTech 5831 Cordless Telephone (Base) was evaluated for compliance to FCC RF exposure requirements at maximum power level of 29.6dBm (0.918W) EIRP while operating with a 33% duty cycle. The VTech 5831 Cordless Telephone (Base) is a Base unit with an outer antenna. The VTech 5831 Cordless Telephone has no body worn applications. The VTech 5831 Cordless Telephone (Base) was evaluated for both body exposure and direct contact SAR (extremities) at low, middle and high channels for the frequency range 5744.736MHz to 5825.952MHz, with keyboard side up, top side up, left side up. The maximum 10g SAR (1.22W/kg) was found for the peak RF output power of channel #00 (5744.736MHz) with the top side of the device facing up (Graph 1). At a separation distance of 15.0 mm from the top side of the device the maximum 1g SAR was found to be 1.18W/kg. The operational manual will contain a warning stating that bystanders and parts of the user’s body other than extremities, must be at least 20.0mm away from the device and its antenna. Evaluation data and graphs are presented in this report. All measurements conducted and documented in this report were performed while the DUI was used in wireless mode. Based on the measured results and on how the device will be marketed and used, it is certified that the product meets the requirements as set forth in the above specifications, for the RF exposure environment. The results presented in this report relate only to the sample evaluated. Page 3 of 51 Project # -VT5831 BASE-3899 51 Spectrum WayTel.
