USING THE STOCKWELL WITH YOUR DEVICES

THE STOCKWELL HAS A USB POWER OUTPUT SOCKET ON THE BACK. YOU CAN PLUG IN AND CHARGE YOUR USB CHARGEABLE DEVICE. THE STOCKWELL WILL POWER YOUR USB DEVICE EVEN THOUGH IT IS PLAYING MUSIC AND RUNNING ON BATTERY POWER.

BLUETOOTH AUTO CONNECTION

WITH THE HELP OF BLUETOOTH TECHNOLOGY YOU CAN EASILY CONNECT YOUR BLUETOOTH-COMPATIBLE DEVICES TO THE STOCKWELL OVER A SHORT RANGE WIRELESS CONNECTION. THIS ALLOWS YOU TO USE THE STOCKWELL AS A SPEAKER PHONE WITH YOUR BLUETOOTH-ENABLED SMARTPHONE OR CONNECT IT WITH A TABLET OR COMPUTER AND STREAM MUSIC DIRECTLY TO IT.
FOLLOW THESE STEPS TO PAIR THE STOCKWELL WIRELESSLY TO YOUR BLUETOOTH DEVICE.

THE SPEAKER STORES UP TO FIVE DEVICES AND TRIES TO CONNECT TO THE LAST CONNECTED BLUETOOTH DEVICE FIRST. FOR EXAMPLE, IF THE SPEAKER HAS BEEN CONNECTED TO THE DEVICES: A–B–C–D–E, DEVICE E IS GIVEN FIRST PRIORITY, WHILE DEVICE A IS GIVEN LAST PRIORITY. EVERY TIME THE SPEAKER STARTS UP, IT WILL DO AN AUTO CONNECTION OF DEVICES WITHIN ITS RANGE.

THERE IS ANOTHER WAY TO CONNECT TO YOUR STOCKWELL – THE OLD FASHIONED WAY, USING A DOUBLE-ENDED CORD AND THE 3.5MM INPUT.
