The Unication Rechargeable Battery Pack is an optional power 
            source for the Unication UniMax Alert and Ring Tone Amplifier.  This backup power 
            source ensures amplifier operation during AC power outages and also if one wants to 
            use the UniMax in mobile situations.
        
                               
            The Battery Pack consists of three “AA” NiMH (Nickel Metal Hydride) rechargeable 
            batteries and has a maximum charging time of 10 hours from a completely discharged 
            condition.  The only charger for the Battery Pack is through the UniMax Amplifier 
            and its connected wall transformer.
        
        
            To install the Battery Pack in the UniMax, first remove the retaining screw in the 
            battery door at the bottom of the amplifier and lift off the battery compartment 
            cover.  Then simply insert the pin connector from the Battery Pack into the mating 
            connector inside the battery compartment of the UniMax.  Reinstall the battery cover 
            with the retaining screw to complete the installation.
        
        
            The green Power LED will automatically light when the amplifier is powered by the 
            wall transformer and charging the Battery Pack.
