Auxiliary (AUX) Input:
For devices without Bluetooth, you can use the AUX input.
- Open the rubber flap and connect a 3.5mm audio cable (not included) from your device's audio output to the speaker's AUX input.
- The speaker will automatically switch to AUX mode.
Maintenance
Cleaning:
- Wipe the speaker with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure the rubber flap covering the ports is securely closed after charging or using the AUX input to maintain its waterproof rating.
Water Resistance:
The speaker features an IPX6 waterproof rating, meaning it can withstand powerful water jets. It is suitable for use in wet environments like showers or by the pool. However, it is not designed for submersion in water. Always ensure the port cover is tightly sealed when exposed to water.
Storage:
Store the speaker in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods. Charge the battery periodically if storing for a long time to maintain battery health.
