Operation instructions This quartz watch is equipped with a 433.92MHz transmitter afor use as a car key. After matching the key to the car, press 1 the unlock key to open the door and press 2 the lock key to close the door. 4.Trunk 1.Unlock 2.Lock 3.Panic This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to 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 to correct the interference by one or 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 on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

FCC ID: RPB-BKT02 RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v06: 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. eirp = p t x g t = (E x d) 2 /30 where: p t = transmitter output power in watts, g t = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/20) /10 6 , d = measurement distance in meters (m)--- 3m. So p t = (E x d) 2 /(30 x g t ) Worse case is as below: Field strength = 53.71 dBuV/m @3m (AV) Ant gain 0 dBi; so Ant numeric gain=1 So p t ={[10 (53.71/20) /10 6 x3] 2 /(30x1)}x1000mW =0.00007mW So (0.00007mW/5mm)x √0.43392GHz = 0.000009<3.0 for 1-g SAR Then SAR evaluation is not required.
