If the battery being used cannot supply the required power for Maestro, but does not fall below
4.25V, it is possible that it can cause a slow drain of Maestro’s internal battery. If the internal battery
is completely drained, Maestro 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 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 using the supplied wall charger or switch
to a battery that can supply sufficient energy to both run Maestro and charge the internal Maestro
battery.
Note: In some circumstances, Maestro 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 Maestro’s built-in speaker at high
volume with AGC turned off. The current demand of the speaker and of the display and Ethernet
interface may exceed the battery’s maximum rated output current. This in turn may lead to the
battery shutting down or decreasing voltage below Maestro’s minimum. In this case, running
the radio with AGC on may reduce the power peaks and prevent the error.
In summary, not all batteries will function the same in Maestro and batteries may age and fail over
time. For best results, check the FlexRadio Systems Community for recommendations on batteries
from FlexRadio employees and other FlexRadio owners. Good batteries should provide reliable
operation over many charge/discharge cycles.
4.5 STARTING/STOPPING THE MAESTRO
Maestro is started by pressing and holding the Power button for 5 seconds. Release the button. In
a few seconds, welcome screens will appear, and the front panel buttons will flash, indicating that
the Maestro is running.
Maestro is stopped by pressing the Power button for a moment. In normal circumstances, it can take
as long as 10 seconds for the unit to completely shut down after the screen goes blank. If a
momentary press of the power button does not shut down Maestro, press and hold the power button
until the unit shuts off. This procedure should seldom be necessary.
4.6 WI-FI NETWORK SETUP
Maestro surveys the computer networks available to it at start-up. If it finds a useable network
connection, either a wired Ethernet connection, or a known Wi-Fi connection, the first screen
displayed to the user will be the Select Radio screen. But if it finds no wired Ethernet connection and
no useable Wi-Fi connection, it displays the Choose a Wi-Fi Network screen.
