battery is completely drained, the Maestro “A” and “B” will shut off and will require charging
through the wall charger port on the back of the Maestro (up to 15 minutes may be required before
the Maestro will restart in this condition). Maestro can detect a loss of internal charge on the
battery, and if detected will show this message:
If you receive this message, you should plug in your Maestro “A” or “B” using the supplied wall
charger or switch to a battery that can supply sufficient energy to both run the Maestro “A” and “B”
and charge the internal battery.
Note: In some circumstances, the Maestro “A” and “B” can demand more power from the
battery than it can supply. This may cause Maestro to produce a power supply error and stop.
Known circumstances that can lead to this error include running the built-in speaker at high
volume with AGC turned off. The current demand of the speaker and the display may exceed
the battery’s maximum rated output current. This in turn may lead to the battery shutting
down or decreasing voltage below Maestro “A” and “B” minimum. In this case, running the
radio with AGC on may reduce the power peaks and prevent the error.
In summary, not all battery banks will function the same in Maestro “A or “B”, and batteries age
and fail over time. For best results, check the FlexRadio Community for recommendations on
batteries from FlexRadio employees and other FlexRadio owners. Good batteries should provide
reliable operation over many charge/discharge cycles.
