Turn Alarm Clock On/Off (with ice-alert function)
1. Press the [ALARM] button anytime to show the alarm time.
2. Press [ALARM] button to activate the alarm.
3. Press again to activate alarm with ice-alert function.
4. To disable the alarm, press until the alarm icon disappears.
Set the Alarm Clock
1. Press and hold [ALARM] for 2 seconds to enter alarm setting mode. HOUR will begin to flash.
2. Use [UP] [DOWN] buttons to adjust HOUR, and press [ALARM] button to proceed to MINUTE.
3. Repeat step 2 above to set MINUTE, then press [ALARM] button to exit.
Note: Pressing the [ALARM] button twice when alarm time is displayed will activate the
temperature-adjusted pre-alarm (alarm will sound 30 minutes earlier if it detects outside
temperature is below 26°F (-3°C)).
6. WEATHER FORECAST
The WTH600-E includes a sensitive pressure sensor that predicts weather for the next 12 ~ 24
hours within a 19-31 miles (30 to 50km) radius.
Note:
1. The accuracy of a general pressure-based weather forecast is about 70% to 75%.
2. The weather forecast does not necessarily reflect the current weather conditions.
er forecast is not based on atmospheric pressure; it is based on outdoor
temperature. When the outdoor temperature is below 26°F (-3°C)
will be displayed on the LCD.
7. BAROMETRIC / ATMOSPHERIC PRESSURE
Atmospheric Pressure is the pressure at any location of the Earth caused by the weight of the
column of air above it. One atmospheric pressure refers to the average pressure and gradually
decreases as altitude increases. Meteorologists use barometers to measure atmospheric pressure.
Since variation in atmospheric pressure is greatly affected by weather, it is possible to forecast the
weather by measuring the changes in pressure.

Press and hold the [BARO] button for 2 seconds to toggle between:
ABSOLUTE the absolute atmospheric pressure of your location
RELATIVE the relative atmospheric pressure based on sea level
