Setup
Charging the Speakers
- Connect the charging cable to the charging port on each speaker.
- Connect the other end of the cable to a USB power adapter (not included) or a computer's USB port.
- The LED indicator will typically show red during charging and turn off or change color when fully charged.
- Allow approximately 2-3 hours for a full charge. A full charge provides up to 3 hours of music playtime.
Pairing with a Bluetooth Device (TWS Mode)
To use both speakers together for a stereo experience:
- Ensure both speakers are fully charged and powered off.
- Power on both speakers simultaneously. They should automatically attempt to pair with each other. You may hear an audible prompt indicating successful pairing between the two speakers.
- Once the speakers are paired with each other, one speaker will become the "master" and enter Bluetooth pairing mode (indicated by a flashing LED, typically blue).
- On your Bluetooth-enabled device (smartphone, tablet, computer), go to the Bluetooth settings and search for available devices.
- Select "CJ Tech Speaker" (or similar name) from the list.
- Once connected, the LED indicator on the master speaker will stop flashing and remain solid. You will hear a confirmation tone.
Pairing with a Bluetooth Device (Single Speaker Mode)
To use only one speaker individually:
- Ensure the speaker you wish to use is powered off.
- Power on the single speaker. It will automatically enter Bluetooth pairing mode (flashing LED).
- On your Bluetooth-enabled device, go to the Bluetooth settings and search for available devices.
- Select "CJ Tech Speaker" from the list.
- Once connected, the LED indicator will stop flashing and remain solid.
Operating Instructions
Power On/Off
- Power On: Press and hold the Power button (or designated button) on each speaker until the LED indicator lights up.
- Power Off: Press and hold the Power button on each speaker until the LED indicator turns off.
Audio Playback
- Once connected to your device, open your preferred music or audio application.
- Start playback from your device. The audio will stream wirelessly to the speakers.
- Volume Control: Adjust the volume directly from your connected Bluetooth device.
- Pause/Play: Use the controls on your connected Bluetooth device to pause or resume playback.
Magnetic Connection
The speakers feature magnetic bases that allow them to connect to each other. Simply bring the flat magnetic ends of the two speakers together, and they will snap into place, forming a single, elongated speaker unit. This does not affect their TWS pairing, which is handled wirelessly.
Maintenance
- Cleaning: Use a soft, dry cloth to wipe the exterior of the speakers. Do not use abrasive cleaners, waxes, or solvents.
- Storage: When not in use for extended periods, store the speakers in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the speakers frequently. Recharge them regularly, even if not in constant use.
- Water Exposure: These speakers are not waterproof. Avoid exposing them to water or excessive moisture.
