Read and understand all instructions. 2. Follow all warnings and instructions marked on the telephone. 3. Avoid contact with liquids. Do not locate base unit or handset near water, for example, near a bathtub, wash basin, sink or laundry tub, in a wet basement or near a swimming pool. 4. Avoid using a telephone (other than a cordless type) during a storm. There may be a remote risk of electrical shock from lightning. 5. Do not use the telephone to report a gas leak in the vicinity of the leak. 6. Unplug this telephone from the wall outlets before cleaning. Do not use liquid cleaners or aerosol cleaners on the telephone. Use a damp cloth for cleaning. 7. Place this telephone on a stable surface. Serious damage and/or injury may result if the telephone falls. 8. Do not cover the slots and openings on this telephone. This telephone should never be placed near or over a radiator or heat register. This telephone should not be placed in a built-in installation unless proper ventilation is provided. 9. Operate this telephone using the electrical voltage as stated on the base unit or the owner’s manual. If you are not sure of the voltage in your home, consult your dealer or local power company. 10. Do not allow anything to rest on the power cord or locate this product in an area where the power cord is likely to be damaged by furniture or foot traffic. 11. Do not overload wall outlets or extension cords as this can increase the risk of fire or electrical shock. 12. Never push any objects through the slots in the telephone. They can touch dangerous voltage points or short out parts that could result in a risk of fire or electrical shock. Never spill liquid of any kind on the telephone. 13. To reduce the risk of electrical shock, do not take this phone apart. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect reassembly can cause electric shock when the appliance is subsequently used. 14. Unplug this product from the wall outlet and refer servicing to the manufacturer under the following conditions: when the power supply cord or plug is frayed or damaged; if liquid has been spilled into the product; if the telephone has been exposed to rain or water; if the telephone has been dropped or the case has been damaged; if the telephone exhibits a distinct change in performance; if the telephone does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions. Improper adjustment may require extensive work by a qualified technician to restore the telephone to normal operation if the telephone does not operate normally by following the operating instructions. 15. Never install telephone wiring during a lightning storm. 16. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. 17. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. 18. Use caution when installing or modifying telephone lines. 19. 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 local power company. 20. Do not attempt to open the AC adapter. There are potentially dangerous voltages inside, and there are no serviceable parts. 21. Discontinue use of product and contact Clarity if the product overheats, has a damaged cord or plug, if the product has been dropped or damaged or if the product has come into contact with liquids. 22. Use only the AC adapter provided with this product or a replacement AC adapter provided by Clarity. 23. This phone amplifies sound to loud volumes. To prevent hearing damage, all users of the phone should be informed of the high volume capability of the phone and children should only use the phone when supervised by an adult. 24. Exposure to high volume sound levels or excessive sound pressure may cause temporary or permanent damage to your hearing. Although there is no single volume setting that is appropriate for everyone, you should always use your telephone with the volume set at moderate levels and avoid prolonged exposure to high volume sound levels.

The device was tested at the facility of Intertek Testing Services in Hsinchu, Taiwan. The maximum output power declared by Plantronics Inc. EUT model #XLC3.4 was evaluated in accordance with the requirements for compliance testing defined in FCC OET Bulletin 65 Supplement C (Edition 01-01), RSS-102 and meet the SAR requirement. For the evaluation, the dosimetric assessment system INDEXSAR SARA2 was used. The phantom employed was the head Specific Anthropomorphic Mannequin (SAM) phantom and the box phantom of 2mm thick in one wall. The total uncertainty for the evaluation of the spatial peak SAR values averaged over a cube of 1g tissue mass had been assessed for this system to be ±20.6%. SAR testing was performed at both the left and right ear of the phantom at the two-handset positions stated in the specification. 2mm thick box phantom for body configuration was also evaluated. Testing was performed at the middle frequency of 1900 band with a rechargeable battery and in Normal mode of operation. Any accessories supplied with XLC3.4 have also been tested. The client confirmed the model: XLC3.1 was a series model to model XLC3.4 (EUT), the differences are listed as below. Model Number Differences XLC3.4 1 Base + 1 Handset with LCD XLC3.1 1 XLC3.4 Handset with LCD + 1 charger In summary, the maximum spatial peak SAR value for the sample device averaged over 1g was found to be: Phantom Worst Case Position SAR 1g , W/kg Head Specific Anthropomorphic Mannequin (SAM) phantom EUT Left Tilt to the phantom 0.004 W/kg 2mm thick box phantom wall Separating the Box with belt-clip attached in rear position from EUT with neckloop 0.038 W/kg In conclusion, the tested Sample device was found to be in compliance with the requirements defined in OET Bulletin 65 Supplement C (Edition 01-01) and RSS-102 for head and body configurations.
