About Waterproof
TANK is splash, water, and dust resistant and was tested under controlled laboratory
conditions with a rating of IP68 under IEC standard 60529 Splash, water, and dust
resistance are not permanent conditions and resistance might decrease as a result
of normal wear. Do not attempt to charge a wet TANK; refer to the user guide for
cleaning and drying instructions.
Liquid damage not covered under warranty.
What should I do if my TANK gets wet?
If liquid splashes on your phone, wipe it off with a soft, lint-free cloth-for example, a
lens cloth. Make sure that your phone is dry before opening the SIM tray to dry your
phone, tap it gently against your hand with the USB connector/headphone jack
facing down and remove excess liquid. Leave your phone in a dry area with some
airflow. Placing your phone in front of a fan blowing cool air directly into the USB
connector/head phone jack might help the drying process.
Make sure that your phone is dry before plug in the USB cable/headphone.
