Problem
Not powering on
Solution
Make sure the speaker is fully charged.
Charge for 2 hours, if necessary.
Press and hold the POWER button for 3 seconds.
Make sure the 3.5 mm audio cable is not plugged in.
Make sure the speaker is not paired with any other device,
as it can only pair with one device at a time.
Press the VOLUME + and VOLUME - buttons
simultaneously and hold for 3-5 seconds. This will force
the speaker to forget previously paired devices. Repeat
the steps for pairing as previously described.
Alternatively, disconnect the device from your speaker
and remove HD77 from your device’s pairing list. Try to
pair again.
Not pairing
NOTE: For better call quality, face the microphone when you speak.
