damaged, the proper functioning of device must be checked by the manufacturer authorized service.
Unauthorized opening of the device, mounting inconsistent with this documentation or
any changes to construction of the device can lead to loss of intrinsically-safe features
and/or metrological characteristics and/or radio equipment characteristics. Damage of
any sealing marks causes loss of confirmation of metrological, intrinsically-safe, radio
equipment features of the device.
