Master Power Switch: Turns AC/DC power on/off to the unit. The indicator
glows when you turn the power On. To avoid over-discharging or stressing of
the built-in battery supply, it is recommended that you plug-in and charge the
unit immediately when LED indicator flashes (denotes lower battery status).
Otherwise, the unit will turn off automatically once a pre determined low charge
level is reached as it may interrupt the performances. A full recharge may take
up to 4 hours. When fully charged, make sure to turn the power OFF to
conserve battery power and when not being used.
