GETTING STARTED\

1. Firstly, Pull out the plastic tab by the battery lid at the back of the Monitor.

2. Then the display shows ‘CAL’ (calibration) and counts up to minimum 50. The monitor self-test in this phase. Duration time less than 30 sec.

3. The LCD screen shows up to 4 flashing dashes indicating the time left until radon
   levels are shown. In this phase, data is obtained for an initial radon level calculation.
   The phase duration depends on radon levels, but typically ranges from 6 to 24 hours.
   The indicator at the top left of the screen flashes when the monitor is active.

4. Place the monitor in living areas (e.g., bed room and living room) and in places deemed representative of the air breathed in each living area.

3. If the display shows ‘Err’ and a number , press RESET, remove and reinsert the batteries after cleaning its contacts. If the ‘Err’ persists, contact the seller for support.

HOW TO USE THE MONITOR DISCLAIM

The long term average represents the average radon value for the ongoing measurement, max one 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 hourly) 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 effect 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 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.

Press the button to restart the instrument before a new measurement.
This operation removes all stored radon data.
Remember to note all previous measurement before using the RESET button.
