Information about this Procedure  

For identification purposes, the original Maestro or Maestro “A” are models with serial numbers in the 
form xxxx-xxxx-0100-xxxx and have the power button located at the top left-hand side of the case. 

If the original Maestro (referred to as Maestro “A”) is not used for 6-8 weeks, the internal display 
battery can discharge to such a low level that when power is connected to the Maestro, the display 
cannot initialize the charging circuitry to recharge the internal battery.  In this state, the Maestro is no 
longer operational.  This procedure describes how to recharge the Maestro Internal battery to make the 
Maestro operational again. 

Please Note that if you do not feel comfortable performing this procedure, you can open a HelpDesk 
ticket in order to receive an RMA to have FlexRadio Service perform the battery recharging for a nominal 
fee.
