4.2 Replacing the batteries
Note – Replacing the batteries
• Note that the stations have to be resynchronised each time after you change the batteries in the
measuring or base station.
• To do this, remove the batteries from the other station and then reinsert them, or change them
as required.
Measuring station
• If the symbol is
displayed (next to ‘OUTDOOR’), replace the two AA batteries of the measuring
station with two new ones.
• Open the battery compartment (28), remove and properly dispose of the dead batteries and insert
two new AA batteries with the correct polarity. Then close the battery compartment cover.
Base station
• If the symbol is displayed (next to ‘INDOOR’), replace the three AAA batteries in the base device
with new ones.
• Open the battery compartment (24), remove and properly dispose of the dead batteries and insert
three new AAA batteries with the correct polarity. Then close the battery compartment cover (24).
5. Installation
Note – Installation
• We recommend initially placing the base and measuring stations in the intended locations
without installing them and making all the settings described in
6. Operation
– to do.
• Only install the stations once the appropriate settings have been made and a stable wireless
connection is established.
Note
• The wireless transmission range between the measuring station and base station is up to 30 m
in open spaces.
• Before installation, ensure that wireless transmission will not be disrupted by interference or
obstacles like buildings, trees, vehicles, high-voltage lines, etc.
• To avoid transmission interference, do not operate adjacent wireless devices on the same
frequency (433 MHz).
• Before the final installation, ensure that there is sufficient reception between the intended
installation locations.
• When installing the measuring station, ensure that it is protected from direct sunlight and rain.
• The international standard height for measuring air temperature is 1.25 m (4 ft) above ground.
Warning
• Buy special or suitable installation material from a specialised dealer for wall-mounting.
• Ensure that no faulty or damaged parts are installed.
• Never apply force during installation. This could damage the product.
• Before installation, ensure that the chosen wall is suitable for the weight to be mounted, and
make sure that there are no electrical wires, water, gas or other lines at the installation site
on the wall.
5.1 Base station
• Use the base to position the base station on a level surface.
