1 Introduction
The equipment realizes a partial or complete re-coding system of the RDS signal already contained in the
incoming signal and automatic MPX exchange between the MPX source and another stereo audio source
such as a satellite decoder.
The RDS signal in the MPX can be switched directly to the output or suppressed and replaced completely
or partially.
Internal RDS coder settings, such as PSN, RadioText, PI, PTY, DI strings, will be transmitted in cases where
the unit must be fully replaced by the RDS signal, or if the stereo audio source is aired .
In partial re-coding, only alternative frequency tables are replaced, while the rest of the information will
remain the same as the original RDS signal.
Optional GSM modem add-on modules or ethernet connection interface allow remote control of the
device.

1.2 Warnings
Before attempting any operation, please follow the safety instructions contained in
the following paragraph
The producer declines any liability for damage to people or things due to non-
compliance even if partial, of the following indications
Ensure that the supply voltage corresponds to what is indicated on the apparatus.
Ensure that the electrical system is equipped with ground connection,
Use only power sockets and cables with ground connection
Disconnect power before attempting any operation inside the device
The power cutting device is the power cord, so this should be easily accessible
and the socket must be positioned close to apparatus
Any operation involving the access to internal parts must be performed only by
trained service personnel.
