CARE & MAINTENANCE
1.
Please use the utmost care and do not use excessive force when assembling and
disassembling the different accessories, in order not cause any damage to the product.
2.
Keep the lens away from extreme high temperatures, as under direct sunlight, since it might
damage lens.
3.
Do not clean the lens with any chemical solvents or other materials, which might cause
damage to the lens.
4.
Never look at the sun through the lens.
5.
When mounting the lens on a housing lens port, it is recommended to follow the guidelines
below in order to avoid wearing out the threads of the lens and housing over time:
a.
Prior to installing the lens on the housing, it is recommended to apply a small
amount of silicone grease on the threaded area of the lens (and adaptor, if used) to
reduce the amount of friction.
b.
Install the lens on the housing lens port underwater only and remove it prior to
ending the dive. Once removed, the lens can be mounted on a lens holder. Avoid
having the lens assembled on the housing on land as much as possible, as it is
heavier and exerts more pressure on the threads.
c.
It is recommended to reduce wearing of the threads by using lens mounting
accessories such as bayonet mounts or flip adaptors.
6.
After Dive Care:
a.
Detach the lens from the housing lens port and rinse all lens components in fresh
water.
b.
To ensure that the accumulated salt has completely dissolved, it is recommended to
soak the lens in warm fresh water once in a while.
c.
Wipe the water drops with a soft cloth. Do not leave any droplets to dry on lens
surface, as permanent water spots may remain.
d.
When storing the lens and during transportation, make sure that it is properly
protected in order to prevent scratches, cracks or any other damage to the lens.
e.
Store the lens in a dry and protected area. Storing the lens in a low humidity
environment will decrease the chances of the lens fogging up when submerged in
water.
f.
Do not store the lens in presence of chemicals, solvents or fuels.
