6. Maintenance and Care
6.1. Water Resistance (IPX7)
The PRSCFUM S3 speaker has an IPX7 waterproof rating, meaning it can withstand immersion in water up to 1 meter for 30 minutes. It is protected against water sprays and splashes, making it suitable for use in showers, by the pool, or during light rain.

To maintain its waterproof integrity, ensure the charging port cover is securely closed before exposing the speaker to water.
6.2. Cleaning
Clean the speaker with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components.
7. Troubleshooting
- Speaker will not power on: Ensure the speaker is fully charged. Connect it to a power source using the Type-C cable and try again.
- Unable to pair via Bluetooth: Make sure the speaker is in pairing mode and within range of your device. Disconnect the speaker from any previously paired devices. If using TWS, ensure both speakers are paired to each other first, then connect your device to the primary speaker.
- Poor sound quality or low volume: Check the volume levels on both the speaker and your connected device. Ensure there are no obstructions between the speaker and your device.
- Battery life is shorter than expected: Battery performance can vary based on volume level, LED light usage, and audio content. Ensure the speaker is fully charged before use.
- Buttons are difficult to see: The buttons are designed for tactile feedback. Familiarize yourself with their positions and functions for easier use in low-light conditions or without visual aid.
