Contact the seller if the product requires service or repairs. The
front or back cover must not be opened.
Avoid subjecting the unit to shock, impact, pressure, vibra-
tions, dust and moisture. Condensation can occur if the unit
is moved from a location with high atmospheric humidity to a
cold location. If condensation occurs, remove the batteries and
leave the unit in a dry environment for 2 hours. The unit must
not be exposed to direct sunlight for extended periods. The
unit must be stored under dry conditions, if possible together
with a desiccant such as silica gel.
Use only batteries of type LR3, alkaline AAA batteries. The
batteries must not be exposed to fire or other extreme heat.
The battery terminals must not be touched, and they must be
kept free from dust, sand, liquids and other foreign objects.

The monitor is tested and quality assured at production. It
meets the accuracy specified in the specification table, un-
less it is continuously measured at high radon levels (many
thousand Bq/ m³) over years. We recommend that the unit is
left on all the times.
GETTiNG STARTED
• Insert the supplied batteries. Please observe correct polarity
of your batteries and make sure you install them in the correct

after about 3 minutes. This is indicated by a flashing measure-
ment indicator at the top right of the screen
