WIND CHILL
Wind chill is the apparent temperature felt on exposed skin due to the combination of air temperature and
wind speed. The wind chill reading on the monitor is calculated based on the temperature measured from the
anemometer (channel-1) and the average wind speed.
To change the unit of wind chill temperature, press the "°C/°F" button on the back casing.
GUST WIND AND WIND CHILL ALARM

To clear the memory record, hold "MEMORY" in the max/min display mode.
RADIO-CONTROLLED CLOCK
The unit will start synchronizing the radio-controlled clock after battery/adapter installation. The antenna icon
will flash during synchronization. If the reception of radio-controlled time is successful, the antenna icon with
