Clear All Command (for console)
After you have completed the above setup procedures and have exited the Setup
Mode, please use the Clear All command before putting your weather station into
service.
The Clear All command clears all stored high and low weather data including
monthly and yearly highs and lows and clears the alarm settings. The command is
recommended to properly clear the console of any erroneous data before first
putting the station into use.
1. Make sure wind speed is showing in the wind compass. If wind direction is
showing, press WIND on the console until wind speed appears.
2. Press 2ND, then press and hold CLEAR for at least six seconds.
3. Release CLEAR when you see “CLEARING NOW” displayed at the bottom
of the console’s screen.
