Using the Speaker.

Using this speaker is easy, simply power up the speaker by pressing and holding the power button and search through the Bluetooth settings on your device until you connect with “KRT-20”, once paired the speaker is ready for use.  I connected the Kroots KRT20 speaker easily to an iPhone and played music straight away from my iTunes library.

You can control your music library directly with the Kroots KRT20 speaker, you can skip tracks and increase/decrease volume with ease.

You can play music directly without Bluetooth if preferred using the supplied AUX cable which has a length of 58cm, to use simply plug on end of the cable into the speaker and the other end into your device.

This speaker also comes with a TF card input slot, this enables you to play music directly using a memory card.

Another great feature of this speaker is the handsfree phone call speakerphone function.  This feature enables you to take phone calls simply and easily.  To answer a call you need to press the power button on the speaker, to reject the call press and hold the power button.  Your music will automatically play after you have ended the phonecall.  You can even call back the last dialled number by quickly pressing the power button twice.
