Cat. No. 60.2527.10
Thank you for choosing this instrument from TFA.
Our "Big Air Monitor" shows you how used and polluted your air really
is. It allows you then to ventilate in an energy efficient way and to
ensure a healthy indoor climate at home or in the office.
Headaches, dizziness and fatigue are often due to an excessive
concentration of volatile organic compounds from natural and artificial
sources of emissions.
The air quality sensor detects more than 5,000 substances in the air
which can be harmful to people, for example formaldehyde, solvents,
carbon monoxide, methane or cigarette smoke.

Important!
Please keep in mind that after setting up the instrument a reliable
value is displayed only after about 5 days. The sensor has to
adjust itself to the actual conditions at the installation site and
find a reference level.
Until this process is complete, the instrument initially shows
higher values.

RADIO-CONTROLLED TIME RECEPTION
The time base for the radio-controlled time is a cesium atomic clock
operated by the Physikalisch Technische Bundesanstalt
Braunschweig. It has a time deviation of less than one second in one
million years. The time is coded and transmitted from Mainflingen near
Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a
transmitting range of approximately 1,500 km. Your radio controlled
clock receives this signal, converts it to show the precise time.
Changeover from summer time or winter time is automatic. The quality
of the reception depends mainly on the geographic location. Normally
there should be no reception problems within a 1,500 km radius
around Frankfurt.
