WTH600-en-US_v1.0 12/17
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 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.
3. The “Snowy” weather forecast is not based on atmospheric pressure; it is based on outdoor
temperature. When the outdoor temperature is below 26°F (-3°C), the “Snowy” weather indicator
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.
Select the Display mode
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
Set the Relative Atmospheric Pressure
1. Obtain the atmospheric pressure data for the sea level (the relative atmospheric pressure for
your current location) through the local weather service, internet or other channel.
2. Press and hold [BARO] for 2 seconds until “ABSOLUTE” or “RELATIVE” icon flashes.
3. Press [UP]/[DOWN] button to switch to “RELATIVE” mode.
4. Press [BARO] button again until the “RELATIVE” atmospheric pressure digit flashes.
5. Press [UP]/[DOWN] button to change its value.
6 . Press [BARO] button to save and exit the setting mode.
Note:
1. The default relative atmospheric pressure value is 29.91 inHg (1013 hPa), which refers to the
average atmospheric pressure.
2. When you change the relative atmospheric pressure value, the weather indicators will change.
