Operating procedures
After unpacking the unit for the first time, please charge the unit for about 4~5 hours before any
operation. This is absolutely necessary as the built-in rechargeable battery might have been
discharged naturally due to long shipment and storage time, even though it has been fully
charged in the factory prior to shipment.
To charge the battery, just plug in the DC end of the switch mode power supply into the DC IN
of the unit and charging will start automatically. The charging indicator LED flashes GREEN
during the charging process. When GREEN LED stays glowing, the battery is then fully
charged and operation could now be started.
To operate this portable sound unit, switch on the main POWER, which will glow GREEN.
However, the main POWER switch does NOT switch on the WR module, CD / USB player and
Digital Recorder as each of them has a dedicated Power / Volume control switch indicated by
WR1, WR2. CD/USB Player and Digital Recorder have individual power switch on its panel.
When the Charging / Battery Status Indicator glows RED, it means the built-in rechargeable
battery is weak and needs to be charged. While charging, the unit could also be operated
simultaneously.

Red LED next to it will glow. Switch on the corresponding transmitter (RF).
