International Protection Code (Ingress Protection Rating)
Classifies and evaluates the protection of the 1-channel transmitter against
ingress of solid foreign objects (such as hands and fingers, dust, unintentional
contact) and liquids. The first digit (4) indicates the protection against solid for-
eign objects: in this case the protection against ingress of objects with a diame-
ter of 1.0 mm and more. The second digit (2) indicates the protection against
ingress of liquids: in this case the protection against vertically falling drops
when the enclosure is tilted at an angle up to 15° from its normal position.
ATTENTION
The protection rating applies only to the following condition:
IP42 applies only when the battery cover of the 1-channel transmitter is closed.
Before starting a recording and before cleaning and disinfecting the device,
make sure that the battery compartment is properly closed.
