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.

GETTING STARTED
• Insert the supplied batteries. Measurement will start au-
tomatically after about 3 minutes. This is indicated by a
ashing measurement indicator at the top right of the
screen
• If the screen displays the error message ‘Err’ and a number:
press the RESET button, remove the batteries and put them
back in
• Position the unit in a living area (for example a bedroom
or living room), and in a location that is representative of
the air that is breathed in this room
• The unit should not be exposed to direct sunlight or elec-
tromagnetic radiation; it should be positioned lying at at
least 25 cm from the nearest wall, at least 50 cm above the
oor, and at least 150 cm from the nearest door, window
or ventilation device
• To permit self-calibration, the unit should remain untouched
for the rst few minutes after start-up
HOW TO USE THE MONITOR
• The long term average (LONG TERM AVERAGE) is the aver-
age radon value over the last year (updated once every 24
hours)
• The short term average (SHORT TERM AVERAGE) alternates
between showing the radon value over the last day (1 DAY
– updated every hour) and over the last 7 days (7 DAYS –
updated once every 24 hours)

The long term average is used to identify any potential health
risk. The short term average is used primarily to see the ef-
fect of measures to reduce the radon level – for example by
increasing the ventilation.
The building can be diagnosed by taking measurements
for one week in all living areas, such as living rooms and
bedrooms. This should preferably be followed by long term
measurement in the room which has the highest radon
value. For long term measurement period and action level
we recommend to follow the guidelines from the national
radiation authority.
The RESET button is used when the monitor is moved in order
to take a new measurement. This deletes all stored radon
data. Remember to note the previous measurement before
using the RESET button.
The MODE button is used to obtain information on how many
days measurements have been taken since the monitor was
started for the rst time, or since the RESET button was last
depressed. This information is displayed on the lower half of
the screen for 20 seconds, after which the screen reverts to
the regular display.
It is recommended that the monitor is activated continuously,
and that the batteries are not removed. The batteries last
for about 3 years, and they can be replaced without stored
data being deleted.

DISPOSAL
The monitor and the batteries must not be disposed of as
ordinary household waste. The materials used in the monitor

ensure that electronic equipment and batteries are disposed
of in accordance with national regulations. Users should con-
tact the seller or their local authority for information about
environmentally friendly waste disposal.
