Beaufort Scale
When reading the Weather Index display, you can press the INDEX button to cycle through different
weather indexes in the following order:
Beaufort Scale > Wind Chill > Heat Index > Dewpoint.
The Beaufort scale is an international scale of wind velocities ranging from 0 (calm) to 12 (hurricane
force).
the signal icon will disappear. The temperature and humidity will display “--” for the
corresponding channel.
4. If the signal does not recover within 48 hours, the “--” display will become permanent you
need to replace the batteries of “--” channel’s sensor(s) and then press
