How do I charge and maintain the battery for the QFX PBX-615SM?
The QFX PBX-615SM is a lithium battery-powered PA loudspeaker. To properly charge and maintain the battery, follow these instructions:
Be sure that you have completely charged the battery prior to first use to maximize the battery’s lifespan.
Once the power adapter is connected to a power source, it will automatically begin charging (it takes 2-3 hours to fully charge the lithium battery).
Even if the battery power is low, the speaker will power on when connected to a power source.
When the battery power is low, the battery indicator light is red. When the battery is charged fully, the light indicator will turn off.
Upon completion of the charging, please disconnect the unit.
With standard usage, a fully charged battery can play for about 1-2 hours.
The battery can be recharged about 300 times in its lifetime.
When not in use, the speaker should always be set to “OFF” to prevent the unit from draining the battery.
When the unit is not used for prolonged periods of time, the battery will gradually lose its power. It is recommended to fully charge the battery at least every 60 days.
