Precautions for the Waterproof housing
The waterproof housing is a precision component. When using the waterproof housing, adhere to the following precautions:
1. Do not randomly remove or change the O-ring, key, and lens cover. Otherwise, the waterproof performance deteriorates.
2. Do not put the waterproof housing in a place where corrosive gases are easily generated due to strong acid or alkali. Do not make
the waterproof housing in contact with chemical or corrosive objects, such as strong acid or alkali.
3. Do not put the waterproof housing in a place where temperature is high (50°C) or low (-10°C) for a long time to avoid
deformation.
4. Do not expose the SD21 video camera to sunshine for a long time to avoid deterioration of the waterproof performance.
5. Before use, ensure that the O-ring is intact, the seal is litter-free, the housing is fully sealed, and the buckle is tight.
6. After using the housing in sea water, wash it using fresh water, clean it, and dry it in a cool place.
Precautions for the 3M Dual-side Sponge Rubber
When using the 3M dual-side sponge rubber, adhere to the following precautions:
1. Before fixing the 3M dual-side sponge rubber, select a curved or flat surface to ensure proper contact between the sponge rubber
and the curved or flat surface.
2. Before using the 3M dual-side sponge rubber, clean the surface where the sponge rubber is attached.
3. Before attaching the 3M dual-side sponge rubber, heat the surface of the sponge rubber using an electric blower, especially in a
place where temperature is lower than -20°C.
Notice
When using the SD21 video camera, pay attention to the following notice information:
1. During continuous use, the body temperature of the SD21 video camera increases. This situation is normal.
2. If the SD21 video camera is not used for a long time, remove and maintain the battery properly, and recharge the battery every
six months to ensure the battery performance.
3. During recording, enabling the digital zooming function may affect the image quality.
4. Shooting view angles are slightly different in different working modes of the video camera.
5. If a video file is large, a computer or a special-purpose player is preferred for smooth play.
6. Cyclic recording and frequent recording/deleting operations may leave data fragments in the SD card, causing failure to record or
save files. To solve this problem, just backup the data to an external storage and format the SD card.
