RADIO CONTROLLED WIRELESS WEATHER STATIONMODEL C8243USER’S INSTRUCTIONSC8243-PD08432M Size: 105 x 130 (mm)
1The multifunctional weather station is equipped with manyfunctions providing thorough weather information to you.The receiver unit has a clear, easy-to-read display thatshows the weather forecast, minimum/maximum indoor andoutdoor temperature,moon phase, as well as the time anddate. It is able to receive and display readings from theremote sensors.The 433 MHz technology means no wire installation isrequired and you can place the sensors anywhere you like.With radio controlled function, the current time and date areautomatically synchronized with the time signal transmittedfrom Germany (DCF77) / UK (MSF) / USA (WWVB) (It dependson which version you purchase). The signal can cover adistance of about 1500 km from the related transmitter.and can radiate radio frequency energy and, if not installedand used in accordance with the instructions, may causeharmful interference to radio communications.However, there is no guarantee that interference will notoccur in a particular installation. If this equipment doescause harmful interference to radio or television reception,which can be determined by turning the equipment off andon, the user is encouraged to try to correct the interferenceby one or more of the following measures:•Reorient or relocate the receiving antenna.•Increase the separation between the equipment andreceiver.•Connect the equipment into an outlet on a circuitdifferent from that to which the receiver is connected.•Consult the dealer or an experienced radio/TVtechnician for help.Trade Name: TRGModel Number: 90210TRG Group2047 Westport Center DriveSt. Lovis, Mo 63146, U.S.A.Tel: 1-314-692071720
