Using the Betron D51 Speaker.

To use the Betron D51 in Bluetooth mode simply turn on the speaker using the toggle switch, the indicator light will flash on the front with an audible tone.  Go to your phone or other device and find your Bluetooth settings and find the one that says “D51”.  Pair with the Betron D51 and straight away you can start enjoying your music.

If you want to play music directly from a TF card (Max 64G) simply put the TF card into the TF slot and the Betron D51 will automatically start playing.

You can play music also using the AUX 3.5mm audio port using your own AUX Cable.

You can use the call button when you have paired the speaker to your smartphone and to use simply short press the button to answer a call and short press again to hang up.  Also long press the button when your phone is ringing to reject the phone call.  You can also double press the button to redial the last missed call number.

The Betron D51 takes about 3 hours to fully charge using the charger cable supplied which has a length of 60cm.  The speaker will last for several hours after a full charge.

The working Bluetooth range is around 20M.
