2. Press and hold ALARM to enter the alarm setting.
3. Press + or - to set the desired values.
4. Press ALARM to confirm the setting.
To activate / deactivate the high / low temperature, heat index, wind chill,
humidity and dew point alarms:
1. In the Temperature or Humidity Area, press ALARM repeatedly to select the
desired alarm.
2. Press M I N / M A X to activate or deactivate the alarm.
NOTE The dew point advises at what temperature condensation will form. The wind
chill factor is based on the combined effects of temperature and wind speed.
TEMPERATURE AND HUMIDITY TREND
The trend lines are shown next to the temperature and humidity readings. The trend
is shown as follows:
TREND ICON DESCRIPTION
Rising
Steady
Falling
COMFORT LEVEL
The Comfort Zone icon indicates how comfortable the climate is based on current
temperature and humidity measurements:

WIND DIRECTION / SPEED
The base station provides wind speed and wind direction
information.
To read the wind direction find the compass point the
is pointing to.
The timestamp records the date and time when storing the wind speed readings.
To select the wind speed unit:
Press UNIT (at the back of the base station) to switch between:
• Metres per second (m / s)
• Kilometers per hour (kph)
• Miles per hour (mph)
• Knots (knots)
The wind level is shown by a series of icons:
ICON LEVEL DESCRIPTION
N/A <2 mph (<4km/h)
Light 2-8 mph (3~13 km/h)
Moderate 9-25 mph (~14-41 km/h)
Strong 26-54 mph (~42-87 km/h)
Storm >55 mph (>88 km/h)
To display the AVERAGE and GUST wind:
1. Press SELECT to navigate to the Wind Speed and Wind Direction Area.
will
show next to the Area.
2. Press MODE to toggle between AVERAGE and GUST wind readings.
To display the maximum speed and direction for gust wind:
In the Wind Speed and Wind Direction Area, press MIN/MAX to toggle between wind
speed / MAX GUST wind readings. The timestamp is displayed accordingly in the
Clock Area.
To clear the memories and timestamp for the wind readings:
In the Wind Speed and Wind Direction Area, press and hold MIN/MAX to clear the
readings.
To change the high gust wind speed alarm:
1. In the Wind Speed and Wind Direction Area, press and hold ALARM to enter
the high gust wind alarm setting.
2. Press + or - to set the desired values.
3. Press ALARM to confirm the settings.
To activate / deactivate the high gust wind speed alarm:
1. In the Wind Speed and Wind Direction Area, press ALARM repeatedly to select
the desired alarm.
2. Press
MIN / MAX to activate or deactivate the alarm.
UVI / BAROMETER / RAINFALL
The weather station works with one UV sensor and one rain gauge. The station is
capable of storing and displaying the hourly history data for the last 10 hours of UV
index, and 24 hours of rainfall and barometric pressure readings.
UVI BAROMETER RAINFALL
The bar chart display shows the current and historical data for the UV index, barometric
pressure and rainfall readings.
To view the UV / Barometer / Rainfall readings:
1. Press SELECT to navigate to the UV / Barometer / Rainfall Area.
will show
next to the Area.
2. Press MODE to toggle between UVI / Barometer / Rainfall readings. The
corresponding icon will appear:
UVI BAROMETER RAINFALL
3. Press + or - to view the historical data selected area. The corresponding
historical readings are showing.
NOTE The number shown in the HR icon indicates how long ago each measurement
was taken (e.g. 2 hours ago, 3 hours ago, etc.).
To select the measurement unit for the barometer or rainfall readings:
In the UV / Barometer / Rainfall Area, press UNIT (at the back of the base station) to
switch between:
•
Barometer: Millimeters of mercury (mmHg), inches of mercury (inHg),
millibars per hectopascal (mb / hpa).
• Rainfall: Millime
ters (mm), inches (in), inches per hour (in / hr) or millimeters
per hour (mm / hr).
UV INDEX
The UV index levels are as follows:
UV INDEX DANGER LEVEL ICON
0-2 Low
3-5 Moderate
6-7 High
8-10 Very high
11 and above Extremely high
To change the high UV alarm:
1. In the UV / Barometer / Rainfall Area and UVI reading display,
p ress and hold
ALARM to enter the high UV alarm setting.
2. Press + or - to set the desired values.
3. Press ALARM to confirm the settings.
To activate / deactivate the high UV alarm:
1. In the UV / Barometer / Rainfall Area and UVI reading display, press ALARM
repeatedly to select the desired alarm.
2. Press MIN/MAX to activate or deactivate the alarm.
