sensors in the order of set-up, i.e. the first sensor will have the
temperature/humidity displayed with the number 1 against it and so on.
5. With less than 3 sensors received, the Weather Projection Station will
try to pick up the remaining one in approximately another 3 minutes. If
3 sensors are received, the Weather Projection Station will stop further
reception.
6. Once the outdoor temperature and the humidity have been received
and displayed on the Weather Projection Station, the WWVB time code
reception is automatically started. This takes typically between 6-8
minutes in good conditions.
7. If after 10 minutes, the WWVB time has not been received, use the SET
key to manually enter a time initially. The clock will automatically
attempt to receive the WWVB time from 12:00 to 6:00 a.m. for a
successful reception. When WWVB reception signal is successful, the
received time will override the manually set time. The date is also
updated with the received time. The next reception attempt will occur on
the following day. (Please refer to notes on “About WWVB Radio
controlled Time” and “Manual Time Setting”).
