USING THE INDOOR AIR QUALITY SENSOR
The Cat S61 comes with an indoor air quality sensor. It detects indoor air pollutants (Volatile Organic Compounds or VOCs)
and noties users.
NOTE:
This app is intended to give you a relative indicator of the presence and level of VOCs in your environment. This app is not a
tool for checking whether an area is safe. It must not be used in life threatening situations, or where there is a risk of injury
or illness.
When the device is new, it may take up to 36 hours to calibrate the VOC sensor. This is because there might be residual VOCs
from the manufacturing process that need to work themselves out of your phone.
Measurements from the air quality sensor will be affected if you clean your phone with products that contain VOCs (such as
alcohol or disinfectant). It may take up to 72 hours for the sensor to return to normal.
