Before first use, fully charge the SP850. Connect the micro USB charging cable to the speaker's micro USB port and the other end to a USB power source (e.g., computer USB port, USB wall adapter). The LED display will indicate charging status. A full charge takes approximately 2 hours.

In FM Radio mode, you can enjoy clear FM signals. The USB cable can be connected to the micro USB port and left dangling to act as an external antenna for improved reception, especially in enclosed environments.

• Auto Scan and Save: Press and hold the 'MENU' button to initiate an automatic scan. The SP850 will search for and save all available FM stations in sequential order.
• Manual Tuning: Use the number pad (0-9) to directly input an FM frequency (e.g., press '9', '7', '4' to tune to 97.4 MHz).
• Station Navigation: Use the Previous/Next track buttons to cycle through saved stations.

5.4 Bluetooth Speaker Mode

The SP850 can stream music wirelessly from your Bluetooth-enabled devices.

These modes are available when using Bluetooth or SD Card modes. Press the 'MENU' button and navigate to the EQ settings to select your preferred mode.

5.7 Headphone Use

Connect standard 3.5mm headphones to the headphone socket for private listening. Ensure your headphones do not have an inline controller, as this may cause audio to play from both the headphones and the speaker simultaneously.

5.8 AUX Input

Connect external audio devices (e.g., MP3 players, non-Bluetooth phones) using the provided 3.5mm audio cable to the AUX port.

6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.

• Storage: Store the speaker in a dry environment, away from dust and extreme temperatures.

7. Troubleshooting

8. User Tips

• Improve FM Reception: If you experience poor FM radio reception, connect the micro USB charging cable to the speaker's micro USB port. This cable acts as an external antenna and can significantly improve signal strength, especially indoors.
• Battery Life Extension: To maximize the lifespan of your removable BL-5C battery, avoid completely draining it before recharging. Occasional partial charges are better than frequent deep discharges.
