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 first 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.
GETTiNG STARTED
• Insert the supplied batteries. Measurement will start au-
tomatically after about 3 minutes. This is indicated by a
flashing 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 flat at
least 25 cm from the nearest wall, at least 50 cm above the
floor, and at least 150 cm from the nearest door, window
or ventilation device
• To permit self-calibration, the unit should remain untouched
for the first few minutes after start-up
• N.B.: Dependent on the radon level, expect a few hours
before the display shows other than 0 Bq/ m³. During the
first few days, the reading should be regarded only as an
indication of the radon level
HOW TO USE THE CANARY
• The long term average (LONG TERM AVERAGE) is the average
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)
