User Manual

1 WIRELESS WEATHER STATION C-8105 USER’S INSTRUCTIONS 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, indoor temperature, relative humidity, pressure, moon phase, time and date, as well as the temperature and relative humidity measured and transmitted by the sensor. It is able to receive and display readings from up to 3 remote sensors. The receiver unit retains the minimum and maximum temperatures and relative humidity readings measured at various locations. 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 Frankfurt (DCF77). The signal can cover a distance of about 1500 km from the Frankfurt transmitter. MAIN FEATURES: WEATHTER STATION: 1.

Make sure you insert the batteries the right way round (see polarity information +/- in the battery compartment). 2. Close the battery compartment. 3. Press reset button to re-start the clock and it will synchroise the channels of the transmitter automatically. NOTE: 1. If extra transmitter is added in the future, press reset button to re-start the clock and synchronise the channel once again. 2. The building material and the position of the receiver and transmitter affect the effective range. So try various set-ups will help to obtain the best result. 3. Place the units away from metal objects and electrical appliances to minimize the interference. Position the receiver and the transmitter within effective transmission range: 30 meters in usual circumstances. SETTING WEATHER INDICATOR Important: To get a better result of weather forecast indicator, please set the weather forecast icon according to the current weather condition. 1. In normal time mode, press and hold DOWN key for 3 seconds, weather indicator flashing. 2. Press DOWN key to change the weather indicator in this order: Slightly cloudy – Cloudy – Rainy – Storm – Sunny 3. Choose the suitable indicator according to the current weather. 4. Press TIME key to return to the normal mode or let it automatically return to normal mode after 30 seconds without pressing any keys. Slightly cloudy Cloudy Rainy Storm Sunny
5 NOTE: 1. Do not set the weather indicator when it is raining. Raining will give unstable data. 2. Do not set the weather indicator in nighttime. 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 Frankfurt, Germany (DCF77), provided the device is within about of 1500 km range of the transmitter. When used for the first time (after inserting the batteries or pressing RESET), the clock starts receiving time signals and the reception display flashes. SIGNAL STRENGTH INDICATOR The signal indicator displays signal strength in 3 levels. Wave segment flashing means time signals are being received. The signal quality could be classified into three types: NOTE: 1. It is strongly recommended to start this clock at nighttime and let the clock receive signal automatically during midnight. 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 from interfering sources such as TV set, computer, etc. 3. Avoid placing the unit on or next to metal plate. 4. Closed area such as airport, basement, tower block or factory is not recommended. 5. Do not start reception on a moving article such as vehicle or train.
