C8243-PD08432M Size: 105 x 130 (mm) RADIO CONTROLLED WIRELESS WEATHER STATION MODEL C8243 USER’S INSTRUCTIONS 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. 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 the weather forecast, minimum/maximum indoor and outdoor temperature,moon phase, as well as the time and date. It is able to receive and display readings from the remote sensors. The 433 MHz technology means no wire installation is required and you can place the sensors anywhere you like. With radio controlled function, the current time and date are automatically synchronized with the time signal transmitted from Germany (DCF77) / UK (MSF) / USA (WWVB) (It depends on which version you purchase). The signal can cover a distance of about 1500 km from the related transmitter. Trade Name: TRG Model Number: 90210 TRG Group 2047 Westport Center Drive St. Lovis, Mo 63146, U.S.A.

Press and hold the “MAX/MIN” key for 3 seconds to delete the maximum and minimum temperature records. MAX.temperature record MIN.temperature record 2. 3. NOTE: 1. 2. ABOUT THE MOON PHASE: The unit has 8 different moon phases. It will change according to the lunar calendar. New moon Full moon Waxing crescent Waning gibbous First quarter Last quarter 14 Remove the battery door and insert 3 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. Close the battery door. Press the “RESET” key to re-start the clock and it will synchronize the channels of transmitter automatically. The building material and the position of the receiver and transmitter affect the effective range. So try various locations to obtain the best result. Place the units away from metal objects and electrical appliances to minimize the interference. Position the receiver and transmitter within the effective transmission range: 30 meters in usual circumstances. ABOUT THE WEATHER INDICATOR Waxing gibbous Waning crescent The built-in barometer can notice atmospheric pressure changes. Based on the data collected, it can predict the weather conditions in the forthcoming 12-24 hours. 4. NOTE: 1. 2. 3. 4. 5. 6. The accuracy of a general pressure-based weather forecast is about 70% to 75%. The weather forecast is meant for next 12 to 24 hours. It may not necessarily reflect the current situation. The “Sunny” icon can only appear from 6 AM to 8 PM; while if the weather is Cloudy/Rainy/Stormy during this period, the “Sunny” icon may not appear. The “Moon phase & Star” icon can only appear from 8 PM to 6 AM; while if the weather is Cloudy/Rainy/Stormy during this period, it may not appear either. The “Rainy” and “Stormy” icons are different only in the dropping frequency of the rain. The rain dropping frequency in the “Stormy” icon is faster than that in the “Rainy” icon. The “Snowy” weather forecast is not based on the atmosphere pressure, but based on the outdoor temperature. When the outdoor temperature is below -3°C, the “Snowy” weather indicator will display on the LCD. Sunny Slightly cloudy VIEWING THE CHANNEL The default channel is Channel 1. In normal time mode, press the “UP” key to view the channel from 1 to 3. HOW TO READ INDOOR AND OUTDOOR TEMPERATURE RECORDS Change the temperature unit to °C for Celsius or °F for Fahrenheit by pressing the “°C/°F” key. If the readings go above or below the operating range, the receiver will keep showing the last record within the operation range. NOTE: Cloudy 1. 2. Rainy Stormy Pressing the “SNOOZE / LIGHT” key can stop the current alarm and enter the Snooze mode; while pressing the “ALARM” key can not only stop the alarm but also turn off the Snooze function. Snowy If no signals are received or the transmission is interfered, “---” will appear on the LCD. Relocate the clock or the transmitter in other positions and make sure the transmission is within the effective range of 30 meters approx. 13 ALARM AND SNOOZE SETTING RECEPTION OF RADIO CONTROLLED TIME SIGNAL 1. The time and date are radio-controlled. The current time and date are automatically synchronized with the time signal transmitted from Germany (DCF 77) / UK (MSF) / USA (WWVB) provided the device is within about 1500 km range of the transmitter. When used for the first time (after inserting the batteries or pressing the “RESET” key), the clock starts receiving the time signals and the reception display flashes. 2. 3. 4. 5. 6. In normal time mode, press the “ALARM” key to enter the alarm time mode.
