Setup
1. Charging the Speakers
Your speakers can be charged using two methods: solar power or the included USB-C cable. For initial use, it is recommended to fully charge the speakers via USB-C.
- Solar Charging: Place the speaker in direct sunlight. The integrated solar panel will automatically charge the internal battery.
- USB-C Charging: Open the protective cover on the back of the speaker to access the USB-C port. Connect the provided USB-C cable to the speaker and a compatible power adapter. A full charge typically takes about 2 hours.

3. Bluetooth Pairing (Single Speaker)
- Ensure the speaker is powered on and in Bluetooth pairing mode (indicated by a flashing blue LED).
- On your device (smartphone, tablet, etc.), enable Bluetooth and search for available devices.
- Select "STUDIOFINIX Rock Speaker" from the list. Once connected, the LED will turn solid blue.
4. True Wireless Stereo (TWS) Pairing (Two Speakers)
To achieve a stereo sound experience, you can pair two STUDIOFINIX Rock Speakers together:
- Power on both speakers.
- On one speaker, quickly press the Multi-Speaker Connect button (the icon with two overlapping rectangles). This speaker will become the primary speaker.
- The primary speaker will automatically search for and connect to the second speaker. Once connected, both speakers will indicate TWS mode (e.g., a specific LED pattern or audio cue).
- Now, connect your device to the primary speaker via Bluetooth as described in step 3. Audio will play through both speakers in stereo.

5. Speaker Placement
Place the speakers in your desired outdoor location, such as a garden, patio, deck, or poolside. For optimal solar charging, ensure the solar panel faces direct sunlight. For TWS pairing, keep the speakers within 33 feet (10 meters) of each other for a stable connection.

Once connected, you can control music playback (play, pause, skip tracks, volume) directly from your Bluetooth-enabled device. The speaker's control panel offers basic functions:
- Power Button (⑂): Press and hold to turn on/off.
- Multi-Speaker Connect Button: Quick press to enable TWS pairing. Press and hold to disable TWS mode.

Maintenance
Proper maintenance ensures the longevity and performance of your STUDIOFINIX Rock Speakers.
- Waterproofing: The speakers are IPX7 waterproof. Ensure the USB-C port cover is always sealed when not in use to prevent water ingress. Minor adhesive residue on the base is part of the waterproof sealing process.
- Cleaning: Wipe the speakers with a damp cloth to remove dirt. Avoid harsh chemicals or abrasive cleaners. Regularly clean the solar panel to ensure efficient charging.
- Storage: If storing for extended periods, fully charge the speakers and store them in a cool, dry place.
