3.2.2 Battery Port
The PSR78 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 PSR78 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 PSR78 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.

The power switch is located on the inside of the repeater. Open the 2 latches on the side of the repeater to
