The RSA-U5 is used to connect voice logging recorders to two-way radios that do not have an output for recorders, such as a mobile radio that is used as a base station. Radios with wired connections for remote control (tone, DC, or local) can usually be directly connected to most recorders and do not require the RSA-U5.
Since connections must be made inside of the radio, it should only be installed by a radio service technician that is qualified to service the radio.
