SAFETY
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 re 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.
CALIBRATION
We recommend that the unit is left on at all times. If the unit is
turned o (by removing the batteries) for more than one year,
it should be recalibrated. The same applies if measurement
takes place continuously for one year at values over 35pCi/L.
In the event of continuous operation at lower radon values,
recalibration will not be required for the rst 10 years.
