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, pres-

sure, vibrations, 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 monitor must be stored

under dry conditions.

Use only batteries of type LR03, alkaline AAA bat-

teries. 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.

LIFETIME

The monitor is tested and quality assured by pro-

ducer. It is recommended that the monitor is pow-

ered continuously, and that the batteries replaced

when its low level is indicated on the display.

NOTE: The monitor meets the specied accuracy,

unless it continuously measure high radon levels

(hundreds of pCi/L) over years.

GETTING STARTED

• Insert the supplied batteries. Please observe

correct polarity of your batteries and make sure

you install them in the correct orientation as

advised by the marking in the bottom of the bat-

tery compartment. The display shows a 30 second

start up sequence when the batteries are inserted

(or after a RESET). Then, both the sampling of

the indoor air and the radon level calculation

are started. In this phase the display shows from

4 to 1 ashing dashes indicating how long it is

left to the monitor begins to show radon levels.

Depending on the radon level this phase will

take from 6 to 24 hours. The rst days the result

must only be considered as an indication of the

radon level. The precision of the measurement

increases with longer measurements.

• A measurement is started by:

- inserting the batteries OR

- pressing RESET button.

• The monitor is self-testing for a few minutes after

the start.

• The unit should not be exposed to direct sunlight

or electromagnetic radiation; it should be posi-

tioned lying at at least 10" from the nearest wall,

at least 19" above the oor, and at least 60" from

the nearest door, window or ventilation device.

• The RESET and MODE buttons should be pressed

with a ball-point pen or similar.

HOW TO USE THE MONITOR

• The long term average (LONG TERM AVERAGE)

is the average radon value since last reset or

average for last 12 months if one has measured

more than 12 months (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 – shown after

1 week and updated once every 24 hours).

The long term average is used to identify any po-

tential health risk , and for continuously monitor-

ing that any installed mitigation measures works

properly. The short term average is used primarily

to see the effect of measures to reduce the radon

level – for example by increasing the ventilation.

The building can be diagnosed by taking measure-

ments for one week. 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 it is recom-

mended to follow the guidelines from the national

radiation authority.

When the monitor is moved to another room, a new

measurement should be started (RESET).

The MODE button when pressed once, it will display

the number of days of the on-going measurement:

since the last RESET or since the Power ON. This

information is displayed on the lower half of the

screen for 20 seconds, after which the screen re-

verts to the regular display.

When the monitor is connected to PC with the

USB cable, it displays the connection indicator and

the last digits of its serial number. Read the User

Manual of the CRA software. It is a tool for detailed

analysis of the measurement results.

RESPONSIBILITY

The monitor and the batteries must not be dis-

posed of as ordinary household waste. It is the

user’s environmental responsibility to ensure that

electronic equipment and batteries are disposed

of in accordance with national regulations. Users

should contact the seller or their local authority

for information about environmentally friendly

waste disposal.

Corentium plus has a 1-year warranty against sys-

tem failure. In the event of incorrect use or opera-

tion of the monitor, Airthings AS cannot be held

responsible for any losses resulting from failure or

from the loss of measurement data.
