Operation

Setting Up Your HD77

Press and hold the POWER button for 3 seconds. You will hear a sound cue, and the BLUE LED light will start flashing.

Turn OFF

Press and hold the POWER button for 5 seconds. You will hear a sound cue, and the RED LED will light up and go OFF.

Wireless Pairing

Make sure TREBLAB HD77 is fully charged and that the AUX cable is not plugged in.

1. Turn ON your speaker by pressing and holding the POWER button for 3 seconds. You will hear the sound cue and the LED will start flashing BLUE, indicating that the speaker is in pairing mode.
2. Activate the Bluetooth mode on your device (smartphone, tablet, laptop).
3. Select TREBLAB HD77 from the Bluetooth devices list. Keep it within 3 feet (1 meter) of the speaker while pairing.
4. If necessary, enter passcode 0000.
5. Once HD77 is successfully paired and connected, the LED will stop flashing and stay BLUE.

Re-Pairing

After the initial pairing, the speaker will automatically connect to the previously paired device when turned ON again. If reconnection does not happen automatically, the speaker will start looking for any other previously paired device within the effective distance range. TREBLAB HD77 can remember up to 8 recently paired devices.

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.
• Once paired, the Master speaker's LED indicators will slowly flash BLUE.

To disable the TWS function and disconnect the Master and Slave speakers, press and hold the VOLUME + and VOLUME - buttons simultaneously on the Slave speaker for 5 seconds until the BLUE LED light flashes, indicating the connection is lost.

Audio Playback

• To pause and resume playback when connected wirelessly, press the PLAY button.
• To adjust the volume, press the VOLUME + or the VOLUME - button while listening to music.
• To change the track on the HD77, press and hold the VOLUME + or the VOLUME - button for 2 seconds.

3.5 MM Audio Cable Connection

You can connect TREBLAB HD77 to compatible devices using the supplied 3.5 mm audio cable.

Plug one end of the 3.5 mm audio cable into the 3.5 mm cable port on the side of the speaker (under the rubber cover). Plug the other end into the 3.5mm jack on your device.

Turn the speaker ON. You will hear the sound cue and the LED light will turn GREEN. Now you can play music and audio.

NOTE: On-device control is not supported for the NEXT, PREVIOUS and PAUSE functions when using the 3.5 mm audio cable. Phone calls management using the PLAY / PAUSE button is not supported as well. You will need to make adjustments using your smart device.

Phone Calls

TREBLAB HD77 can be used to make and receive phone calls when connected wirelessly. Audio playback will be paused during calls.

NOTE: For better call quality, face the microphone when you speak.

Troubleshooting

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 3.5mm 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.

Safety Rules

• Don't disassemble or modify your speaker for any reason. Doing this may cause the speaker to malfunction or become combustible. The damage to your device can void the manufacturer's warranty.
• Do not let your device get wet – liquids can cause serious damage. Water damage to your device can void the manufacturer's warranty.
• Make sure the speaker is completely dry before charging.
• Clean only with a dry cloth.
• Avoid exposing TREBLAB HD77 to extreme temperatures (below 37°F / 3°C or above 112°F / 45°C). Extreme temperatures can cause the deformation of the HD77 components and reduce the battery life and the lifespan of your new speaker.
• Don't put the device's LED lights close to humans' or animals' eyes.
• Do not use HD77 during a thunderstorm. Thunderstorms can cause serious malfunction and increase the risk of electric shock.
