Ensure both F18 speakers are powered on.
Disconnect both speakers from any previously paired Bluetooth devices.
On one of the speakers (this will be the primary speaker), double-click the Power button to enter TWS pairing mode.
The two speakers will automatically pair with each other, indicated by a "beep" sound.
Once TWS paired, connect your device to the primary speaker (the one you double-clicked) via Bluetooth. The device will still show "F18" as the name.

Colorful Light Modes

The speaker features 5 dynamic light modes to enhance your listening experience. The light modes automatically cycle or can be controlled by specific button presses (refer to speaker's specific button combination for light control, if any, otherwise it's automatic).

Switching Modes: Short press the 'M' (Mode) button to cycle through Bluetooth, TF Card, and AUX modes.

Maintenance

Cleaning: Wipe the speaker with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
Water Resistance: The speaker is IPX5 waterproof, meaning it can resist a sustained, low-pressure water jet spray. Do not submerge the speaker in water. Ensure the charging port cover is securely closed when exposed to water.
Storage: Store the speaker in a cool, dry place away from direct sunlight and extreme temperatures.
Battery Care: To prolong battery life, charge the speaker regularly, even if not in use for extended periods. Avoid fully discharging the battery frequently.

Troubleshooting

Problem	Possible Solution
Speaker does not power on.	Ensure the speaker is charged. Connect it to a power source using the Type C cable.
No sound from the speaker.	Check if the speaker's volume is turned up. Ensure your connected device's volume is turned up. Verify the speaker is in the correct mode (Bluetooth, TF Card, AUX). If using AUX, ensure the cable is fully inserted and not damaged.
Cannot pair with Bluetooth device.	Ensure the speaker is in Bluetooth pairing mode (flashing indicator light). Make sure Bluetooth is enabled on your device. Move the speaker closer to your device (within 10 meters). Forget "F18" from your device's Bluetooth list and try pairing again. If TWS paired, ensure you are connecting to the primary speaker.
TWS pairing fails.	Ensure both speakers are disconnected from any other Bluetooth devices. Place speakers close to each other during TWS pairing. Follow the TWS pairing steps precisely (double-click power button on one speaker).
Sound distortion or poor quality.	Reduce the volume on both the speaker and your device. Move closer to the speaker to avoid interference. Ensure the audio source is of good quality.
