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
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.
