CHARGING YOUR BUILT-IN BATTERIES
An automatic charging system is built-in to your Liberty Sound System. It is designed to properly charge and
maintain the systems built-in batteries. To charge batteries:
When in AC mode the system automatically transfers power from the battery charger to the power amplifier at
high volume output, causing the Charger LED to flicker.
1. Plug the power cord into your sound system
2. Plug the other end of the cord into AC outlet
Charger LED will stay on during charging
3. Batteries will fully charge in approx. 6-8 hrs
Charger LED will flash
CARING FOR YOUR BUILT-IN BATTERIES
It is very important that you fully charge the batteries in your new sound system
before the first time its used. To preserve battery life it is also recommended
that batteries be fully charged as soon as possible after every use regardless of
the length of operation.
UNDERSTANDING THE BATTERY LEVEL INDICATOR
LED Flashing Red: Battery charge is very low, in 15-30 minutes the Battery
Protection Circuit will turn the system off.
LED Off:
Battery is completely drained and must be charged.
NOTE: System Can Be Used While Batteries Charge!
OPERATING IN AC MODE
Plug your sound system into an AC outlet. Operate as normal while charg-
ing the built-in batteries at the same time. The Charger LED will light during
charging and flash when the battery is fully charged.
BATTERY SERVICE TIME
With the batteries fully charged you can expect approx.:
6-8 hrs @ Medium Volume 2-4 hrs @ Full Volume
Of continuous music input
(longer for speech). Service time will vary depend-
ing on control settings and use of accessories
(built-in CD player, wireless
receivers and/or a companion speaker).
IMPORTANT: Always Store Your System w/
Batteries Fully Charged!
SYSTEM STORAGE & BATTERIES
Always store your sound system with the batteries fully charged. For extended
