Setting the time
• Hold the button “SET” down for about 3 seconds, until the display format appears
(“12h” or “24h”) ashing.
• By briey pressing the button “+” you can switch between the 12hr and the 24hr display format.
In the 12hr display format the temperature is automatically displayed in °F (degree
Fahrenheit), in the 24hr display format it is in °C (degree Celsius).
• Conrm the setting by briey pressing the “SET” button.
• The hours start to ash.
Set the hour by repeatedly pressing the button “+”. For a quick adjustment hold the button
for a longer period of time.
• Conrm the setting of the hours by briey pressing the “SET” button.
• The minutes will start ashing.
Set the minutes by repeatedly pressing the button “+”. For quick adjustment, hold the button
down for a longer period of time.
• Conrm the minutes setting by briey pressing the “SET” button.
If no button is pressed for a few seconds, the settings mode will be closed automatically.
Display MIN/MAX memory
The minimum and the maximum temperatures are stored automatically, and can be displayed
by pressing the button “MIN/MAX”.
• Press the “MIN/MAX” button briey once: The minimum temperature is displayed; in the lower
display, “MIN” will appear.
• Press “MIN/MAX” button again briey: The maximum temperature is displayed; in the lower
display, “MAX” will appear.
Delete MIN/MAX memory
Hold down the “MIN/MAX” button for about 3 seconds, all minima and maxima stored will be deleted.
Directly after deletion, the current temperatures, next measured, will be saved as the
new minimum or maximum.
Mounting or setting-up the outside sensors
The outside sensor can be mounted on the wall using the holder provided or you can use the holder
as a stand base. Select an appropriate installation location. It has to be in an area, protected against
direct rain and direct sunlight. Ideally, mount the sensor underneath a roof projection.
Never operate the outside sensor in or under water; it is not water-tight!
Use the appropriate mounting material, depending on the mounting location; e.g. drill holes
and use wall plugs.
Please ensure that no cables or wires are damaged when drilling/screwing the
holder into position.
Mounting or setting-up the display unit
The unit is equipped with a retractable foot on the back for placing on a table. Place the device
on a sufciently large level surface. It is also possible to mount it on a wall. A hole on the back
of the display unit is for hanging it up, e.g. on a screw or a nail.
Please, ensure again that no cables or wires are damaged.
When deciding on the placing, it may be necessary to us an appropriate pad material
on valuable furniture to avoid impressions or scratches on the surface.
Notes on the range
Normally, when operated in, for example, a family home, fault free operation should be
possible. Like any other appliance that works with radio transmissions, interferences can occur.
The product works in the 868 MHz range, which is also used by other products. This
is why there may be restricted operation and range due to devices that work on the
same, or a neighbouring, frequency.
The range for line-of-sight contact of transmitter and receiver (the so-called “free
eld range”) is a maximum of 100m. It is greatly reduced in buildings (theoretically),
depending on the construction and environmental conditions.
Ferroconcrete, metal doors or the use of metal-coated heat insulation can have a
negative effect on the range. The range is shortened.
Other causes for a reduced range:
• High frequency disturbances of all kinds (e.g. microwave ovens).
• Buildings of all types (walls etc.) and vegetation.
• Conductive metals, which are located in the vicinity of the units or within or close to the radio
route, e.g. radiators, metal insulation glass windows, reinforced concrete oors etc.
• Inuence on the antennas’ radiation pattern due to the distance of transmitter or receiver to
conductive surfaces or objects (metal tables, but also human bodies or oors).
• Broadband interferences in urban areas that reduce the signal-to-noise ratio; the signal is not
recognised because of the “noise”.
• Irradiation from insufciently shielded electronic devices, e.g. computers operated openly,
or similar.
Care and cleaning
a) Inserting/changing the battery
In the event of a battery replacement, in of one of the units (outside sensor or display unit) the
basic conguration has to be redone.
Remove the batteries from all the units and proceed as described above under “Commissioning”.
This is necessary because a random security code is generated for every
commissioning. It protects the radio transmission against interference.
Thus, the display unit would only be able to receive data from the outside sensors
coded and recognised when the batteries were rst inserted.
A battery replacement is necessary, if the display contrast on the display unit is poor, if no
values are indicated at all, or if an outside sensor is no longer received.
b) Cleaning
• Disconnect the product from the power supply before cleaning.
• Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as
they can cause damage to the housing and malfunctioning.
• Clean the outside of the product with a soft, dry, ber-free cloth.
• Do not immerse the product in water.

Disposal
a) Product
Electronic devices are recyclable waste and must not be disposed of in the
household waste. At the end of its service life, dispose of the product according to
the relevant statutory regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from
the product.
b) (Rechargeable) batteries
As the end user, you are required by law (Battery Ordinance) to return all used
(rechargeable) batteries; disposal of them in the household waste is prohibited!
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable)
batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold.
You thus full your statutory obligations and contribute to the protection of the environment.
