4.1 Installation and charging of battery pack
EVERSE loudspeakers come pre-installed with a high capacity Li-Ion battery pack. Charge
the battery for 24hours before the first use to ensure maximum battery run time and life
expectancy.
To charge the battery:
4 Plug the MAINSIN while the battery is installed in the EVERSE loudspeaker.
After the first full charge, the expected battery charge times are as follows:
– 4hours or less with no signal and the power switched off.
– 6hours or less with the power switched on and audio playing at high output levels.
The LCD will display while the battery is charging with the power switched off.
The LCD will display when the battery has reached full charge.
Notice!
Battery self-discharge
All Li-Ion batteries experience self-discharge over extended periods (several months). If a
battery sits for an extended period without being charged, the battery may fully discharge.
It may take longer than normal to fully recharge. If this occurs, allow the battery to charge a
full 24hours again before using.
Inspect your loudspeaker and battery monthly and recharge the battery. This will help
maintain the batteries run time and extend its useful life.
Notice!
Battery run time
Powering external devices via the DC power jack, USB connection, and/or phantom power
will reduce battery run time, depending on the power required. Typical use cases may
experience a reduction of 25% to 50% of total run time. User results may vary.
Other factors such as the output level, the source material, the ambient temperature, and
the number of times that a battery has been discharged also affect run time of lithium-ion
battery systems.
To remove and reinstall the battery for inspection or replacement:
1. Place the loudspeaker grille side down with the battery door facing you on a flat non-
scratching surface such as a workbench with a rubber mat.
2. Fully loosen the two finger tab screws by turning them counter-clockwise.
3. Gently but firmly pull on the battery pack by the finger pull located on the back of the
battery door.
