Before Using: ① For optimal performance of the Dive Case, please update your camera's firmware to the latest version before use. ② Please read these instructions carefully and prepare the case properly before use. Failure to observe these instructions may cause damage to the camera, battery or other parts, for which Insta360 won't assume responsibility. Please use this product responsibly to prevent accidental damage. ③ Improper maintenance may affect product performance. Each time before use, it's suggested to securely close the Dive Case (no camera inserted) and immerse it in water to check for leaks as described below: • Latch the dive case and slowly immerse it in water, stopping if air bubbles emerge from the case. • Immerse the Dive Case and operate the buttons under water for 2-3 minutes checking for any air bubbles. • Take the Dive Case out of the water and dry it thoroughly with a soft, dry cloth, then open and check for any water inside. Note: the Dive Case should not be submerged in water deeper than 30 meters (98ft) without the camera inside, otherwise it may be damaged. ④ When sealing the Dive Case, be sure that the parts of the Dive Case in contact with its rubber seal are free of any foreign objects and the rubber seal has not moved off the rim of the Dive Case. ⑤Never open or close the Dive Case in a location with a lot of sand, dirt, dust or other small particles. Otherwise, the performance of the Dive Case will be affected and the camera may be damaged. ⑥The Dive Case is not shock-resistant. Applying strong vibrations, shocks or pressure to the product may result in damage, failure or reduced waterproofing performance. ⑦While using GO 3/GO 3S in the Dive Case, the maximum height from which you can dive into the water is 2 meters (6.56ft). The Dive Case is protected against drops onto solid ground from a maximum height of 1 meter (3.28ft). ⑧Glue may be visible inside the outer edge of the Dive Case lens. This is normal and will not affect waterproofing performance. Maintenance: ① Do not open the Dive Case while it is wet. ② After using the product in seawater, remove the camera and soak the Dive Case in fresh water for 5-10 minutes. If the Dive Case is not washed after use in seawater, residual salt may cause water leakage. After soaking the Dive Case in fresh water, rinse it gently under a faucet. Never apply a high-pressure water flow from a single direction, as it may cause leakage. ③ Ensure that the Dive Case is firmly closed before washing. After washing the Dive Case, wipe away any water droplets remaining on the surface with a soft, dry cloth. Do not dry it with a hair dryer, clothes dryer, or stove. ④ Ensure there is no sand on the Dive Case before drying. Sand may scratch the product surface when wiped with a cloth. ⑤ Do not store the Dive Case in a hot and humid environment. In particular, do not leave it inside a hot car. ⑥ Do not wash the Dive Case with soap, neutral detergent, or alcohol cleaning products. This may degrade the waterproofing performance. ⑦ Do not clean the Dive Case with organic solvents (such as diluents, alcohol, or gasoline). ⑧ Store the product in a dry, well-ventilated location.
