Lowe battery indicator 5. 433.92MHz 6. RF distance: 100 meters 7. Functions: 7.1 One button: TX, press it once to send the signal one time. 7.2 When put the battery into it, it will test the temperature and humidity and sent the data one time. 7.3 When put the battery inside, it goes to receive the RCC, it will exit when receiving successfully. It will be exit automatically after 7 minutes when the RC receiving failed. 7.4 RCC receiving time: every 1:00, 2:O0，3:00，4:OO and 5:00 7.5 When RCC DST, it will send the main unit. Keep this instrument and the batteries out of reach of children. Batteries contain harmful acids and may be hazardous if swallowed. If a battery is swallowed, this can lead to serious internal burns and death within two hours. If you suspect a battery could have been swallowed or otherwise caught in the body, seek medical help immediately. FCC Warning 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. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Note: 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. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.

RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 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 = pt x gt = (EXd) 2 /30 where: pt = transmitter output power in watts, gt = 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 Sopt = (EXd) 2 /30 x gt Ant gain= 0 dBi ; so Ant numeric gain= 1 Field strength =71.82dBμV/m @3m So Pt={ [10 (71.82/20) /10 6 x3] 2 /30x1 }x1000 mW = 0.00456 mW So (0.00456 mW/5mm)x √0.43392 GHz =0.0006 < 3 Then SAR evaluation is not required
