4. Installation och justering

4.1 Inledande förberedelser

Before first use, it is recommended to clean the lenses to remove any manufacturing residue that may cause fogging. Apply a small amount of non-abrasive toothpaste or a commercial mask defogger to the inside of the lenses, rub gently, and rinse thoroughly with fresh water. Repeat if necessary.

4.2 Justering av rem

The mask features integrated, flexible buckles for easy strap adjustment. To adjust the strap:

1. Place the mask gently on your face without the strap around your head.
2. Hold the mask in place and pull the strap over your head.
3. Use the buckles on each side of the mask to tighten or loosen the strap. Press the release buttons on the buckles to adjust the strap length.
4. Adjust until the mask feels secure but not uncomfortably tight. Overtightening can cause leaks and discomfort.

4.3 Fit Test

To check for a proper seal:

1. Place the mask on your face without using the strap.
2. Inhale gently through your nose. The mask should suction to your face and stay in place without holding it.
3. If air leaks in, adjust the mask's position or the strap tension until a good seal is achieved. Ensure no hair is caught under the silicone skirt.

5. Bruksanvisning

5.1 Donning the Mask

After adjusting the strap, place the mask over your eyes and nose, ensuring the silicone skirt forms a complete seal around your face. The strap should rest comfortably around the back of your head, above your ears.

5.2 Mask Clearing

If water enters the mask, it can be cleared underwater:

1. Tryck maskramens ovansida ordentligt mot pannan.
2. Exhale slowly and steadily through your nose. The exhaled air will push the water out from the bottom of the mask.
3. Fortsätt andas ut tills allt vatten har tryckts ut.

5.3 Utjämning

As you descend, pressure builds up in the mask. To equalize this pressure and prevent discomfort, gently pinch your nose through the mask's nose pocket and blow gently through your nose. This equalizes the pressure in your ears and sinuses with the surrounding water pressure.

6. Underhåll

6.1 Efter varje användning

Rinse your mask thoroughly with fresh, clean water immediately after each use. This removes salt, chlorine, and other residues that can degrade the silicone and lenses over time. Avoid using harsh chemicals or abrasive materials.

6.2 Förvaring

Store the mask in a cool, dry place away from direct sunlight and extreme temperatures. Prolonged exposure to UV light can cause the silicone to yellow or become brittle. Store it in its original case or a protective container to prevent scratches to the lenses.

6.3 Djuprengöring

Periodically, if the mask shows signs of stubborn residue or persistent fogging, a deeper clean may be necessary. Use a mild soap solution (e.g., baby shampoo) and soft cloth to gently clean the silicone skirt and lenses. Rinse thoroughly afterwards.
