SET UP
NOTE: Use good quality alkaline batteries and avoid rechargeable
batteries.
1. Have the indoor weather station and remote temperature sensor close
together during setup.
2. Place the batteries into the remote sensor first then into the weather
station. See below.
INSTALLING THE BATTERIES
REMOTE SENSOR (FIG 1)
1.
Battery compartment retaining screw
Fig 1
Unscrew and remove the battery
compartment retaining screw.
2. Remove the battery
compartment cover.
3. Insert two alkaline AAA batteries
into the remote sensor.
NOTE: Make sure that you follow
the polarity diagram inside
the battery compartment.
4. Replace the battery compartment cover.
INDOOR BASE STATION (FIG 2)
1.
Fig 2
Remove the battery cover.
2. Observing the correct polarity,
install three alkaline AA batteries.
3. Replace the battery cover.
4. Do not press any buttons for at
least ten minutes.This will allow
time for the weather station to
start receiving information from
the sensor,
• If successful the indoor weather station will show the outdoor
temperature and humidity.

5
• If the indoor weather station does not display these values after 1
minute, the signal search will try again every two hours until a signal is
found.
• Once the remote sensor temperature and humidity values are displayed
for 10 minutes you can place the sensor outdoors.
RADIO TIME SIGNAL
After the initial setup period, the weather station will start to search for a radio
time signal.
The time and date signal is sent by a highly accurate government-operated
atomic clock. The weather station will continually scan for the radio controlled
time signal each day.
• If reception is unsuccessful, then the radio time signal icon will not
appear and the manually entered time will be displayed. See page 9 for
instructions on how to enter the time manually.
• If reception has been successful, the radio time signal icon will be
shown and the received time and date will overwrite any manually set
time and date.

6
MOUNTING
BASE STATION
• There is a folding stand at the
rear of the base station, which
allows the unit to be stood onto
any flat surface.
• The base station may also be
wall mounted using the
hanging hole on the rear of the
unit.
NOTE: It is important to check that
the radio signal can be
received at the chosen location before permanently mounting
either of the units.
REMOTE SENSOR
NOTE: To obtain acurate temperature readings, do not mount the
remote sensor in direct sunlight. We recommend that you mount
the sensor on an outside north-facing wall.
NOTE: Obstructions such as walls, concrete, and large metal objects will
reduce the transmitting range.
1. Use 3 screws to fix the wall bracket
to the wall.
2. Clip the sensor into the wall
bracket as shown.
3. The remote sensor will transmit the
outdoor temperature and
humidity back to the weather
station.

USING THE WEATHER STATION
WEATHER FORECASTING
Sunny Cloudy
Partly Cloudy Rain
The four weather icons Sunny, Partly Cloudy, Cloudy and Rainy represent the
weather types.
NOTE: Weather forecasting is based upon the change of air
pressure.The pressure threshold can be adjusted from level 2-4
(default level 2). See “General Settings” on page 9. Areas that
experience frequent changes in air pressure require a higher
setting.
WEATHER TENDENCY ARROWS
The weather tendency arrows are located between the weather icons and
provide a forecast of the weather you can expect.
• Arrows pointing to the right - mean that the air pressure is increasing
and the weather is expected to improve.
• Arrows pointing to the left - mean that the air pressure is decreasing
and the weather is expected to deteriorate.
EXAMPLES OF CHANGING WEATHER ICONS:
This is based upon the current pressure and the pressure change over the last
six hours.
• If the weather is changing, the arrows will flash for three hours
indicating changing weather.
• If the weather conditions become stable, then the arrows will not
flash.

8
STORM WARNING
When there is a fall in pressure (above the threshold) over a period of 3 hours,
the storm warning feature will activate.
• The “cloud with rain” icon and tendency arrows will flash for 3 hours
indicating the storm warning feature has been activated.
NOTE: The storm threshold can be adjusted by the user from level 3-9
(default level 4). See page 9.
