“Auto” means that the system automatically recharges the battery when it’s nearly
depleted (85% capacity used), drawing power from the internal AC/DC for both the battery
charger and the audio circuits. When the battery is charged, the system reverts to it,
switching the internal AC/DC off. Moreover, a charge is initiated every time the unit is put
into standby. This mode ensures the longest life to the battery.
In AC mode, the unit is forced to use the AC/DC converter. This is useful in case of battery
failure or absence.
In Manual mode, the units uses the battery down to its complete depletion and then
switches off. This is useful when a listening session is in progress and the user doesn’t
want the unit to switch to the AC/DC which may lower the sound quality compared to the
battery supply. This way, the battery usage is a little longer and may allow for completing
the listening session.
When the battery discharge reaches 85%, the unit starts indicating it by displaying the
battery icon on the display. When depletion goes further on, the battery icon is replaced by
the “BAT LOW “ indication. In this case, the user may initiate a charge cycle by operating
the rear mains switch.
In both Auto and Manual modes, when the units is put into standby during a charge cycle
and then reactivated before the charge is terminated, the battery will be selected as power
source whenever its charge level is more than 15%.
