3.2.4 I/O connector (RJ45)
The I/O connector is a RJ45 type and contains different signals for connecng to external equipment. It can
be used to connect an external speaker, and there are also 600 Ω audio input/output, available for connecng

key input. This connector is also used to connect the baery package (BU-872) for communicaon between
the radio and the baery package.
All funcons are described in the table below:
