The wireless M-Bus module has been designed
to form part of Kamstrup's hand-held Wireless
M-Bus Reader system, which operates within
the unlicensed frequency band in the 868 MHz
area. The radio module is available with either
internal or external antenna. Please note that
both antenna types use the same connection.
* The wireless M-Bus module must be connected to an internal or external antenna. When
mounting an external antenna ensure that the antenna cable is not jammed or damaged when
the calculator is assembled. Before mounting or replacing modules the power supply to the
meter must be switched off. The same applies to mounting of an antenna.
