according to which random transmission it receives. Pressing any key will stop

this process. The process also stops automatically if no keys are pressed for a

few minutes.

Once the remote temperature has been received and is displayed on the

Weather Station, the DCF-77 time code reception is automatically started.

This takes typically between 3 - 5 minutes in good conditions. This time period

is an excellent opportunity to locate the transmitter(s) in suitable location(s)

outdoors. In order to ensure sufficient 433MHz transmission however, this

should under good conditions be no more than 25 meters from where the

Weather Station will be finally positioned (see notes on "Positioning" and

"433MHz Reception").

If after 10 minutes the DCF time has not been received, use the SET key to

manually enter a time initially. The clock will automatically attempt to receive

the DCF time at each full hour. When this is successful, the received time will

override the manually set time. The date is also updated with the received

time (Please refer also to notes on "Radio controlled time" and "Manual

time setting").
