TRUE WIRELESS STEREO (TWS) – PAIRING TWO SPEAKERS

The TWS technology allows you to use two speakers paired wirelessly to create a wireless dual-channel system, delivering a true stereo sound effect. While using this function, one speaker (Master, left channel) is paired with a smart device, the other (Slave, right channel) speaker is paired with the Master speaker.

Select the Master speaker and pair it to the smart device following the steps from the WIRELESS PAIRING section. Then turn this speaker OFF.
Turn OFF the Bluetooth on the smart device.
Place the Master and Slave speakers near each other (the distance should not be over 3 feet /1 meter).
Turn ON both speakers.
Double click the POWER button on the Master speaker. The LED indicators will start flashing BLUE and GREEN, indicating pairing with the Slave speaker.
Turn On the Bluetooth on the smart device. The speakers will connect automatically.

TROUBLESHOOTING

Problem	Solution
Not powering on	Make sure the speaker is fully charged. Charge for 2 hours,

if necessary. Press and hold the POWER button for 3 seconds.
Not pairing| 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 finding a wireless driver on your laptop| Make sure your laptop supports wireless connections. If it doesn’t, you will need an external wireless USB adapter compatible with your laptop. For further details, consult with your laptop manufacturer.
Frequent disconnection and noise| Ensure that the distance between your device and the speaker is less than 30 feet / 10 meters.
Ensure that nothing is blocking the signal between your device and the HD77.
Check if the speaker is running out of power.

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.

We recommend fully charging the HD77 speaker at least twice a month to maintain sufficient battery life.
