Testing the Radio Unit Voltage Supply
The power supply is ensured by the plug-in power supply unit, which is perma-
nently connected to the radio unit. If a 230 VAC connection is not available, the
radio unit can be operated with a battery box.

The voltage must be between 9 and 15 V (DC voltage). The current consumption
is 230 mA. This means that with a capacity of 1.1 Ah the battery box can provide
up to 5 hours of measuring time.
Standard Radio Unit Distances to the PBX
Take note when planning that with distances up to 500 m the power supply can
be provided as of the AD2 bus. From 500 m up to the maximum for the AD2 bus
of 1,200 m, a local power supply has to be provided with the recommended plug-
in power supply unit, i. e. you need to provide a 230 VAC connection.
