for use in. In areas that experience sudden changes in weather (for example
from sunny to rain), the Weather Station will be more accurate compared to
use in areas where the weather is stagnant most of the time (for example
mostly sunny).

If the Weather Station is moved to another location significantly higher or
lower than its initial standing point (for example from the ground floor to the
upper floors of a house), remove the batteries and re-insert them after about
30 seconds. By doing this, the Weather Station will not mistake the new
location as being a possible change in air-pressure when really it is due to the
slight change of altitude. Again, disregard weather forecasts for the next 48-
60 hours as this will allow time for operation at a constant altitude.

THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators
(located on the left and right hand side of the weather icons). When the
indicator points upwards, it means that the air-pressure is increasing and the
weather is expected to improve, but when indicator points downwards, the
air-pressure is dropping and the weather is expected to become worse.
Taking this into account, you will see how the weather has changed and how
it is expected to change. For example, if the indicator is pointing downwards
together with cloud and sun icons, then the last noticeable change in the
weather was when it was sunny (sun icon only). Therefore, the next change
in the weather will be the cloud with rain icons since the indicator is pointing
downwards.

Note :
Once the weather tendency indicator has registered a change in the air
pressure, it will remain permanently visualized on the LCD.

INDOOR TEMPERATURE AND MIN/MAX RECORDS
The indoor temperature and indoor MIN/MAX records are displayed on the
last section of the LCD.

Note: The MIN/MAX indoor temperature range is 15ºF to 99ºF with 1ºF

resolution (-9ºC to + 38ºC with 1°C resolution).

OUTDOOR TEMPERATURE AND MIN/MAX RECORDS
The outdoor temperature and outdoor MIN/MAX records are displayed on the
last section of the LCD.

Note: The MIN/MAX outdoor temperature resolution range is -40ºF to 140ºF

with 1ºF resolution (-40ºC to + 60ºC with 1°C resolution).

RESETTING THE INDOOR AND OUTDDOR MIN/MAX RECORDS
Note: All the MIN/MAX records will be reset at the same time.

In normal display mode, press and hold the MIN/MAX RESET key for 3

LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the batteries require
changing.

915 MHz RECEPTION CHECK
The Weather station should receive the temperature data within 3 minutes
after set-up. If the temperature data is not received 3 minutes after setting up
(not successfully continuously, the outdoor display shows “- - -” ), please
check the following points:
1.

The distance of the Weather station or transmitter should be at least 1.5
to 2 meters (5 to 6.5 feet) away from any interfering sources such as
computer monitors or TV sets.

Avoid positioning the Weather station onto or in the immediate proximity
of metal window frames.

Using other electrical products such as headphones or speakers
operating on the same signal frequency (915MHz) may prevent correct
signal transmission and reception.

Neighbors using electrical devices operating on the 915MHz signal
frequency can also cause interference.

Note:
When the 915MHz signal is received correctly, do not re-open the battery
cover of either the transmitter or Weather station, as the batteries may spring
free from the contacts and force a false reset. Should this happen
accidentally then reset all units (see Setting up above) otherwise
transmission problems may occur. The transmission range is about 100 m
from the transmitter to the Weather station (in open space). However, this
depends on the surrounding environment and interference levels. If no

reception is possible despite the observation of these factors, all system units
have to be reset (see Setting up).

POSITIONING THE TEMPERATURE STATION:
The Weather Station may be hung onto wall easily or free standing.

To wall mount
Choose a sheltered place. Avoid direct rain and sunshine.
Before wall mounting, please check that the outdoor
temperature values can be received from the desired
locations.

Fix a screw (not supplied) into the desired wall,
leaving the head extended out the by about 5mm.

Fold the stand and hang the station onto the screw.
Remember to ensure that it locks into place before
releasing.

Free standing
With the foldout stand, the weather station can be placed
onto any flat surface.
