CHARGING
One full battery charge provides up to 9 hours of playing time at maximum volume,
and up to 12 hours at medium volume. When the battery is running low, you will
hear a sound signal.
TREBLAB HD77 may be used while charging in both Wireless Mode and 3.5 mm
audio cable modes.
To charge the speaker, plug one end of the supplied cable into the Micro USB
charging port under the rubber cover at the side of the speaker. Plug the other
end of the charging cable into a standard USB port. It takes up to 4 hours to fully
charge.
If the speaker is turned OFF, the LED light will turn on RED. If the speaker is turned
ON and connected to the device, the PURPLE LED will light up. The RED light will
turn GREEN or the PURPLE light will go BLUE when the speaker is charged.
Be sure to use a 5V DC, 0.5-2 A adaptor or charger. Using the power source with
lower power will increase the overall charging time. Maximize the battery lifespan
by charging your speaker through a computer's USB port.
Unplug HD77 from the charging cable and the cable itself from the power source
when not in use.
If the speaker is left unused, even the fully charged battery will lose its charge
over time.

Questions and answers
Unit not charging. Can I order a new charging cord?
The speaker doesn’t turn green to indicate a full charge. It’s been charging 24 hours.
The TREBLAB HD77 speaker should turn green when fully charged. If it is not turning green after 24 hours of charging, possible reasons include:
1. A faulty charging cable or adapter.
2. A loose connection at the charging port.
3. The speaker being turned ON while charging, which may cause a different LED indication (PURPLE instead of GREEN).
4. A battery or hardware issue preventing proper charging.
Try using a different cable and adapter, ensure a secure connection, and check if the speaker is turned OFF while charging. If the issue persists, contact TREBLAB support.
