• The manufacturer is not responsible for incorrect displays or measured values and
any consequences which may arise thereof.
• The display unit is only intended for use in dry, enclosed indoor spaces, it must
not get damp or wet.
• If the product is used in vehicles, it must be operated only when the situation
is appropriate and allows the operation and use of the unit. Do not use/operate
the product if this distracts you from driving the vehicle. The same is true for the
reading out of measured values from the product's display.

please contact our technical department or another specialist.
Battery information
• Batteries should be kept out of the reach of children.
• Do not leave batteries lying around in the open; there is a risk they may be swallowed by
children or pets. If they are swallowed, consult a doctor immediately.
• Leaking or damaged batteries can lead to caustic burning of the skin. Therefore, use suitable
protective gloves.
• Liquids leaking from batteries are very chemically aggressive. Objects or surfaces coming
into contact with these liquids could be considerably damaged. Batteries must therefore be
stored in a suitable location.
• Ensure that the batteries are never short-circuited, taken apart or thrown into a fire. There is
a risk of explosion!
• Do not recharge normal, non-rechargeable batteries. There is a risk of explosion!
• Make sure that the polarity is correct when inserting the batteries (pay attention to plus/+
and minus/–).
• If the device is not to be used for a long time (e.g. storage) remove the batteries. Old batte-
ries may leak and cause damage to the product, which will lead to the loss of the warranty/
guarantee!
• For the proper disposal of batteries, please read the chapter "Disposal".
Inserting / replacing batteries
• Open the battery compartment at the rear of the device by pushing the battery compartment
cover out by approx. 3 mm (observe the arrow on the battery compartment cover). After this,
the battery compartment cover can be removed.
• Insert two batteries of type LR44 observing the correct polarity (the plus pole "+" must point
outwards towards you). Close the battery compartment again.
• The battery needs changing when the display contrast is reduced considerably.
Assembly
• The display unit can be mounted in a suitable location at the rear using the hook- and loop-
tape strips enclosed. Make sure the surface is smooth, level, dry and free of grease and dust.
The display unit can also be mounted on a sloped surface using the foldable clip at the rear.
When mounting the device in a vehicle, make sure not to cover displays or control elements
of the vehicle or to impair their function.
• The sensor can be fastened in a suitable location using the adhesive tape that is already
present at the bottom. Make sure the surface you have chosen to attach the sensor to, is
smooth, level, dry and free of grease and dust.
Protect the cable between the display unit and sensor from sharp edges and do not bend it.
Lay the cable so that it does not hinder you while driving the vehicle.
The sensor should be mounted in a protected place which is not exposed to direct
sunlight or humidity/moisture, otherwise you will have incorrect measurement valu-
es. The ideal place in vehicles is, for example the area between the door and car
body. However, it is essential to ensure that the sensor is not crushed and the door
or car body is not damaged by the sensor casing.
• If the voltage of vehicle battery is to be displayed, insert the cigarette lighter plug into a cor-
responding cigarette lighter socket of the vehicle.
The product is only suitable for a cigarette lighter socket of 12 V!
Display indications / operation
a) Basic display
The display appears after the batteries are inserted.
In the left of the display, you can find the time and next to it the inside temperature ("IN") and
outside temperature ("OUT").
The voltage at the right edge of the display is only shown when the cigarette lighter plug is
inserted into a corresponding socket of the vehicle and a voltage is present.
b) Setting the time
• Press and hold the "TIME" button for about 3 seconds and the "12H" or "24H" display for the
12 or 24-hour mode will flash.
• Briefly press the "UP" or "DOWN" button to switch between the 12 and 24-hour mode. In the
12-hour mode, "PM" appears left to the time during the second half of the day.
• Briefly press the "TIME" button, the seconds of the time flash. Briefly press the "UP" or
"DOWN" button to reset the seconds to "00".
