Operation
Power Sources
Your BST-400 can operate as a wireless, cord free sound machine or a
wireless Bluetooth speaker because it includes a built-in rechargeable
battery. You can also keep your BST-400 plugged into a USB power
source for continuous operation without recharging.
To Power By Built-In Rechargeable Battery:
1. Prior to using your BST-400 in the wireless, cord free mode for the first
time, please completely charge the built-in battery.
2. Connect the provided USB Charging Cable to the included AC-charger,
computer or laptop USB port. The unit’s Charge Indicator is brightly
illuminated while charging. It takes about up to 6 hours to charge the
battery. When charging is completed, the Charge Indicator will be very dim.
3. Disconnect the USB Charging Cable and operate your BST-400 as
described below.
4. When the unit is in low power status, the red Charge Indicator and
amber LED will flash. Please recharge the battery of your BST-400 when
this occurs.
Note: When the battery is fully discharged, it needs about 30 minutes of
charging before you can use the unit again.
