PRECAUTIONS Battery Usage and Maintenance 1.W hen operating on its built-in lithium battery, Panda Touch only has a b attery life of 0.5 hours. To preserve the battery and prolong product l ifespan, it is recommended to cha「ge Panda Touch immediately o「 turn it o仔once the b atte「Y is depleted. 2.The s creen may flicker when the lithium battery ’ s power is low. This is no「mal and serves as a 「eminder for use「S that the batte「y is nearing depletion. ln response, users ShOL』Id promptly charge the batte「y口「 turn off Panda Touch. 3.When powe「ing Panda Touch th「ough the cha「ging dock connected to the 30 p 「inter, if the printer is turned off, we 「·e commend switching Panda Touch's powe「 switch to OFF. This prevents potential damage from prolonged power deficiency. Scan the QR code to access the on line manual for m。re product info and instructions.

RF EXPOSURE EVALUATION METHOD FCC ID: 2BAS6-TOUCHV1 Applicable standard： In accordance with FCC 47 CFR part 2 (2.1093) this device has been defined as a portable device which is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable devices must be evaluated using the specified in FCC 47 CFR part 2 (2.1093) and ANSI/IEEEC95.1-1992. and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528-2003. Per FCC KDB 447498 D01 v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances s 50 mm are determined by: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.

[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] < 3.0. 2. SAR Test Exclusion Thresholds is 3.0 for separation distance 5mm. Therefore, SAR test is not required.
