3. The two speakers will automatically search for and connect to each other. Once connected, you will hear a confirmation sound, and the LED indicators on both speakers will synchronize.
4. Now, connect your device to the primary speaker via Bluetooth as described in Section 5.1. The audio will play through both speakers in stereo.

5.3 AUX Connection

To connect to devices without Bluetooth functionality:

6.2 LED Light Effects

The RIENOK S4 features dynamic LED lights on both ends that change with the rhythm of the music. These lights are an integral part of the speaker's design and enhance the listening experience. There is no specific button to control the light modes mentioned in the product description, implying they operate automatically with music playback.

7. Maintenance and Care

• Cleaning: Wipe the speaker with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Water Resistance: While the speaker is IPX7 waterproof, it is designed to withstand splashes and brief immersion (up to 1 meter for 30 minutes). Do not submerge it for extended periods or expose it to high-pressure water jets. Ensure the charging port cover is securely closed before exposing the speaker to water.
• Storage: Store the speaker in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the speaker frequently. Charge it regularly, even if not in use for extended periods.
