Power Supply Instruction

1. How to use DC power supply:
   •  When 8 lithium-ion batteries are installed and fully charged, the unit can be operated continuously for approximately 6~8 hours in standby mode. However, the operating time varies depending on the playing mode (speech or music mode), loudness, and freshness of the batteries.
   •  In the case the power is not turned on, the Battery Meter indicators will not light on. When the power is turned on, the red LED on the Master Power Switchwill light on; meanwhile, 1 to 3 battery meter indicators light on to denote the battery power is enough for normal operation. Only 1 battery meter indicator lights on or the red LED on the power switch flashes denote the battery power is insufficient and immediate charge is necessary. If no battery meter indicator lights on when the power switch is on, it denotes the batteries are over discharged or possibly faulty.
   • Always store the sound system with the batteries fully charged and recharge every 3 months. If the batteries are not charged for an extended period, they might be over-discharged and damaged, and can’t be charged anymore.
   • MA-828 / MA-929 use 32650 LFP batteries; MA-727 uses 26650 LFP batteries. Replace 8 batteries all together to ensure each one has the same capacity for optimal operating hours.
2. How to use External Power Supply:
   •  When connecting the external power supply, the 4 battery meter indicators will light on immediately to denote that the power supply is functioning normally and the rechargeable batteries are fully charged. And, flashing battery meter indicators denote the rechargeable batteries are in charging status.
