For Best PerformanceOperating RangeR The range of operation depends on the topography of your office, weather, or usage conditions,because signals are transmitted between the base unit and the handset/desk phone by radio waves.R Normally, you get greater range outdoors than indoors. If there are obstacles such as walls, noise mayinterfere with your telephone calls. In particular, high metal shelves or reinforced concrete walls willrestrict your operating range.R A handset/desk phone may not work when it is too far from the base unit depending on the structure ofthe building.R We strongly suggest you hold the bottom half of the handset to ensure better call quality. Because, theantenna is located in the upper half of the handset (KX-TPA60 only).NoiseOccasional noise or interference may occur due to electromagnetic radiation from objects such asrefrigerators, microwave ovens, faxes, TVs, radios, or personal computers. If noise disturbs yourtelephone calls, keep the handset/desk phone away from these electrical appliances.EnvironmentR Keep the product away from heating appliances and devices that generate electrical noise, such asfluorescent lamps and motors. These noise sources can interfere with performance of the product.R Do not place the product in rooms where the temperature is less than 0 °C (32 °F) or greater than40 °C (104 °F).R To avoid damage, charge the battery only in temperatures ranging from 5 °C (41 °F) to 40 °C (104 °F).R Allow 10 cm (3–15/16 in) clearance around the product for proper ventilation.R Avoid environments with excessive smoke, dust, moisture, mechanical vibration, shock, or directsunlight.R The apparatus is designed to be installed and operated under controlled conditions of ambienttemperature and a relative humidity.Routine CareR Unplug the AC adaptor from the AC outlet and disconnect the Ethernet cable before cleaning.R Wipe the product with a soft cloth.R Do not clean the product with abrasive powder or with chemical agents such as benzine or thinner.R Do not use liquid cleaners or aerosol cleaners.R Clean the terminal of the charger periodically.PlacementR Do not place heavy objects on top of the product.R Care should be taken so that objects do not fall onto, and liquids are not spilled into, the product.R Place the charger on a flat surface.R Place the KX-TPA65 in a location where the Signal Strength Indicator shows either Medium (" ") orStrong (" ").10Important Information
