Altec IMW575 - Waterproof Feature; IPX67 Rating Explained

Waterproof Feature
The IMW575 has an IPX rating of 67 meaning it is waterproof at a depth of 3 feet or approximately 1 meter for
up to 30 minutes. You MUST have the waterproof cover on the back of the IMW575 closed and fully sealed to
achieve this level of waterproof. Failure to do this voids the warranty.
