FAQs & How-Tos

2 results
  • My device is waterproof, but what about salt water or chlorine water?
    Your JBL speaker is waterproof with IPX7 rating. (IPX7 means it can survive immersion in 1 meter/3.3 feet for up to 30 minutes.) To maintain the looks and functions of your speaker, please make sure to rinse it with fresh water after using it at a swimming pool or the ocean, then dry off all covers and areas where water can gather. The standard for waterproofing is for tap water. Chemicals and salt in your pool or the ocean can damage the waterproof seals or harm the surface finish over time if not rinsed off after use.
  • What is the procedure to reset Xtreme?
    With the speaker ON, press and hold the VOL+ and Pause/Play buttons for 5-6 seconds. The Xtreme shuts down, and is now reset. You will need to 'forget' the speaker in Bluetooth settings on your phone/tablet in order to pair it again.
