Function Test - VOLTCRAFT CO-300 Bedienungsanleitung

Function
The three coloured LED lights indicate the CO
Green: 400 – 1000 ppm
Yellow: 1000 – 2000 ppm
Red: >2000 ppm
It is possible that a CO concentration can reach 2000 ppm within a short time depending on

the room size, number of people in the room and other variables. The CO
typically higher in rooms where windows are usually closed for extended time, which is the case
in winter; therefore, it is lower in summer.
If the yellow or red LED light goes on, you should ventilate the room. The indication may not
change immediately as the room air takes some time to mix with the outside air.
Some people perceive air as stale when the CO
Detailed information on carbon dioxide and the effects of certain gas concentrations
on humans (as well as limits f or living and working areas in your country) can be
found on the Internet or in specialist literature. Always check the source of data/
information (it should be reliable) and make sure it is up-to-date; in Germany, for
example, it is the Environment Agency: www.umweltbundesamt.de).
Switching the alarm sound on/off
The alarm is triggered by the yellow LED light (long beeps) or red LED light (short beeps).
Set the switch (3) on the bottom of the product to position "I" to enable the alarm sound or to
position "O" to disable the alarm sound.

Function test

A function test can be performed by slowly blowing into the sensor opening (4) while exhaling.
If the product functions properly, the high CO

It may take some time for the yellow or green LED light to go on again until the air saturated
with carbon dioxide in the housing is mixed with the normal air room.

Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may
damage the casing or cause the product to malfunction.
