Figure 3: Battery Backup Port
The SDR module can be connected to an ADRF-BBU (ADRF Battery Backup) to provide power during a power
failure. If an ADRF-BBU is utilized, connect the ADRF-BBU to the SDR via the external battery port as shown in
Figure 4.
(WARNING: The circuit switch on the ADRF-BBU must be set to OFF before connecting the ADRF-BBU
to the SDR to prevent damage to the repeater or the ADRF-BBU and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation
procedure of our battery box.
