If AC mains power is interrupted, the system will automatically switch over to battery power.
Remote On / Off switching of the AC mains power will automatically switch the system over
to battery power.
1.10 Power On Indicator (7)
The "Power On" indicator remains illuminated (green) while the loudspeaker system is On.
The Power On indicator also serves as a "Remaining Charge" indicator when the rechargeable
battery is powering the system:
y Slow blinking LED
approximately 25% of battery charge remains
y Fast blinking LED
less than 25% of battery charge remains
1.11 Battery Charging Circuit & Loading Indicator (8)
Note:
Before the system is used for the first time or if it has not been connected to AC mains
power for several months, connect it to AC mains power supply (with the Power On switch
in Position 0) and charge the battery for at least 6 hours.
The Loading indicator remains illuminated (red) while the battery is charging. After the
battery is fully charged, the Loading indicator will be off and the built-in charging circuit will
automatically switch to trickle charging. The charging circuit is completely separate from the
amplifier power supply and will charge the battery from any state of charge, at a smooth,
controlled rate up to a full charge. The power amplifier (when connected to AC mains) can
deliver full power, even while a completely discharged battery is being charged.
Charging times (with the Power On switch in Position 0), for a completely discharged battery,
are approximately as follows:
y 6 hours
to 90% capacity
y 10 hours
to 100% capacity
For a partially discharged battery, the charging time will be shorter.
The internal battery will not recharge when the loudspeaker is being powered by an external
battery source. The built-in charger will not recharge external batteries connected to the EXT
BATTERY socket.
For fastest battery recharging, set the Power On switch to Position 0 and connect the AC
mains cable to an AC mains power supply.
The loudspeaker system, even with a fully charged battery, can be connected (long term) to
AC mains power without damage to the battery. The system does not need to be continually
connected to AC mains power when stored (see table below for remaining capacity) and may
be stored for several months, although not recommended, without recharging. Battery
lifetime is estimated to be approximately 3 years or approximately 5000 recharge cycles,
with no memory effect.
