5.3. Change of operation mode). Some models of the E-RM 30 (e.g. chapter 2.1. Type list) are able to detect attempts to manipulate the water meter by using an external magnetic field (for example by using a magnet). The actual transfer of data between the water meter and the radio module is based on an optical principle (just like the radio module itself) and is therefore not affected by a magnetic field. -
