Hi Jerry, Are you using this method to pair your device?

Pairing
The Bluetooth-enabled device that you wish to stream audio to your speaker system must
fi rst be paired to the speaker. The process is simple, and in most cases the pairing process
needs to be done only once.
To pair your Bluetooth-enabled device with the speaker:
1. Make sure your device's Bluetooth is turned on. See the wireless and/or network settings
menu on your device to check.
2. If the speaker isn't already on, press the On-Off button to turn it on. You will hear a beep
to indicate the speaker is turned on. The indicator light on the back of the speaker starts
fl ashing blue.
3. Press and hold for 3 seconds the Pair button to enter pairing mode. You will hear 2 beeps
to indicate pairing mode is entered. The indicator on the back of the speaker starts blinking
faster.
4. Open the Bluetooth settings menu on your device. Select "AR SPEAKER" from the list of
devices available (you might have to scan for devices). If your device asks for a password,
enter "0000".
5. A confirmation screen will appear on your device once the speaker and the device are
successfully paired. The blue indicator turns solid blue to indicate successful connection.
The speaker is now ready for you to stream audio from your device.

turn both phone bluetooth and speaker bluetooth off. then turn them back on. the speaker's light should be flashing indicating its searching for a device to pair with. as its flashing make sure your phones bluetooth is visible and searching. they will pair and your phone will tell you and the speakers light should quit flashiing and just remain on.

Where the bluetooth options on your phone will depend on your phone.

So to put the speaker into Bluetooth pairing more slide the power switch to the right hand side. If the speaker has power then a blue light to the right should light up.

Once this is done you will need to find the Bluetooth devices option on your phone. This will be located somewhere under settings - connectivity.
When you locate the device in bluetooth devices, select it then select pair.

If you can't find the bluetooth options on your phone, comment on this answer with the phone name and model and I will see if I can find out for you.
