Only the supplied Y-cable may be used to connect the power supply. The radio unit must
be connected to a power supply with an output power limited to 15 W. Alternatively, the
radio unit can be protected with a fuse (taking into account the DC rating of the fuse) at
the DC input with a fuse rating of F 250 mA/fast-acting.
