SET key

Note:

In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is due to a random security code

assigned by the transmitter at start-up. This code must be received and stored by the weather station in the first 3 minutes of power being supplied to the

transmitter.

DCF RADIO CONTROLLED TIME

The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time

deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5

kHz) and has a transmitting range of approximately 1,500 km. Your radio-controlled weather station receives this signal and converts it to show the precise

time in summer or wintertime.

The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1,500 km radius of

Frankfurt.

DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at 03:00 am, then the next reception takes place the next hour and

so on until 06:00am, or until the reception is successful. If the reception is not successful at 06:00 am, then the next attempt will take place the next day at

02:00 am.

If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please take note of the following:

x Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 meters.

x Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a

window and/ or point its front or back towards the Frankfurt transmitter.

x During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to

keep the accuracy deviation below 1 second.

LCD SCREEN

The LCD screen is split into 3 sections displaying the information for time/calendar, indoor data, weather forecast and air pressure history, and outdoor data.

* When the signal is successfully received by the weather station, the outdoor transmission icon will be switched on. (If not successful, the icon will not be

shown on LCD). The user can then easily see whether the last reception was successful (icon on) or not (icon off).
