#1 How do you know Philips Bluetooth speaker is fully charged?
When the speaker is being charged, and if the speaker is off, there will be blinking LED to indicate that it is charging. if the speaker is on, the speaker beeps once but there is no charging indication on the LEDs.
speaker is switched on, hold both the - and + keys at the same time for 7 seconds until the speaker is off. Then wait for the speaker to reset and switch on again automatically. The audio quality is poor after connection with a Bluetooth-enabled device.
