4 PANTONE: 445C SIZE:A4 Mode: C8366-PD13138M RADIO CONTROLLED PROJECTOR CLOCK WITH WEATHER FORECAST User’s instructions Thank you for your purchase of this Radio Controlled weather station clock. The utmost care has gone into the design and manufacture of your clock. This instruction is used for DCF & MSF & WWVB versions, and the LCD display and temperature used US version for reference. So please read the instruction carefully according to the version you purchased and keep the manual well for future reference. The multifunctional weather station is equipped with many functions providing thorough weather information to you. The receiver unit has a clear, easy-to-read display that shows weather forecast, minimum/maximum indoor and outdoor temperature, as well as time and date. It is able to receive and display readings from up to 3 remote sensors. The 433 MHz technology means no wire installation is required and you can place the sensors anywhere you like.

WALL-MOUNTING HOLDER: -Use it to support the transmitter on the wall. 7. TABLE STAND -Use it to stand the transmitter on the desktop. BEFORE USING THE TRANSMITTER 1.Remove the battery door. 2.Insert 2 x AA size batteries into the battery compartment. Make sure you insert them the right way according to the polarity information marked on the battery compartment. 3.Replace the battery door. Note: 1. Once the channel is assigned to one transmitter, you can only change it by removing the batteries or resetting the unit. 2. Avoid placing the transmitter in direct sunlight, rain or snow. WEA THER STATION 1.If using the DC Adaptor to power the clock, plug the adaptor into the DC jack. If using battery, remove the battery door and insert 3 x AA batteries into the battery compartment. Make sure you insert the batteries the right way according to the polarity information marked on the battery compartment. 2.Replace the battery door. 3.Press the “RESET” key to re-start the clock and it will synchronize the channels of transmitter automatically. Note: 1.The building material and the position of the receiver and transmitter affect the effective range. So try various locations to obtain the best result. 2.Place the units away from metal objects and electrical appliances to minimize the interference. Position the receiver and transmitter within the effective transmission range: 30m in usual circumstances. 3. You may use the batteries and adaptor togother to power the unit that the batteries can power the clock when the adaptor powered off. RECEPTION OF RADIO CONTROLLED TIME SIGNAL The time and date are radio-controlled. The current time and date are automatically synchronized with the time signal transmitted from Germany (DCF 77)/U.K. (MSF)/ USA(WWVB). When used for the first time (after inserting the batteries or pressing the “RESET” key), the clock will start to receive the RC signal in 5 minutes with the signal strength indicator flashing. SIGNAL STRENGTH INDICATOR The signal indicator displays signal strength in 4 levels. Wave segment flashing means time signals are being received. The signal quality could be classified into four types: IN OUT 1 2 3 456789121118 16 10 15 ONOFF 17 14 13 5 1 32 4 6 7 Note: 1. Everyday the unit will automatically search for the time signal at 2:00, 8:00, 14:00 and 20:00. 2. Always place the unit away…

RF Exposure Info

Analysis Report Report No.: 13030039HKG-003 FCC ID: OQH-000000-13-01 The equipment under test (EUT) is the Remote Sensor transmitter of the Radio Controlled Projector Clock With Weather Forecast operating at 433.92MHz. The EUT is powered by 3.0VDC (2X 1.5V "AA" batteries). The EUT will transmit RF signal to the corresponding receiver and the receiver will display the humidity and temperature on the screen. Antenna Type: Internal, integral Antenna Gain: -1dBi Nominal rated field strength: 76.0dBμV/m at 3m Allowed field strength of production tolerance: +4dB and -3 dB Maximum allowed field strength of production: 80.0dBuV/m @ 3m According to the KDB 447498: Based on the Maximum allowed field strength of production was 80.0dBμV/m at 3m in frequency 433.917MHz, thus; The EIRP = [(FS*D) ^2*1000 / (30*1.64)] = 0.03mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.04mW. Threshold = 3.0 * (min. test separation distance, mm)/ SQRT(f in GHz) = 3.0 * ( 5 / SQRT(0.43392) ) = 23mW Since the above maximum output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
