Version 2.5, 2021-06-21

CAUTIONS FOR USE

•A water-tight test in a bathtub or similar is highly recommended when using

the system for the first time and after the changing of port and O-ring(s).

Submerge the enclosure fully for several minutes, and watch for any bubbles.

•Before cleaning the enclosure, remove the batteries or the DC coupler, or

disconnect the power plug from the outlet.

•Do not use solvents such as benzine, thinner, alcohol, kitchen detergents, etc,

to clean the enclosure, since it may deteriorate the external case or the

coating may peel off.

•Do not leave the enclosure with the lens facing the sun, as rays of light from

the sun may cause it to malfunction.

•Do not leave any metal items (such as clips or hex keys) near the contact

areas of the power plug or near the batteries.

•Store batteries in a cool and dry place with a relatively stable temperature:

oRecommended temperature: 15ºC to 25ºC (59ºF to 77ºF)

oRecommended humidity: 40%RH to 60%RH

•Do not store batteries for a long time while fully charged. When storing

batteries for a long period of time, we recommend charging them once a year.

•Do not use lubricants from other brands with the nitrile rubber O-ring on this

enclosure, only use the lubricant provided by Mantis.

•Discontinue use immediately should you notice any leakage.

•Store the enclosure in a robust, shock-proof container during transportation;

avoid transporting while turned on.

•When travelling by air, do not close the enclosure latches, as this may lead to

a pressure difference between the atmosphere and inside the enclosure.

•Care must be taken when opening the enclosure, as pressure may build up

inside the enclosure which increases the opening force.

•Do not open the product in a wet or sandy environment. Protect the interior

from moisture and debris in order to prevent malfunction or leakage.

•Do not store the product in an environment of high humidity.

•Do not leave the enclosure in direct sunlight for prolonged periods.

•Keep out of reach of children, failure to do so could result in injury.

•Defective products should be shipped to our factory or distributors for service.

Unauthorised disassembling and/or modifications could result in malfunction

or leakage.

CARE AND MAINTENANCE

1. Soak the enclosure in fresh water after each salt water use, during which all

control buttons/knobs should be operated a few times to avoid the

accumulation of salt residue; wipe the enclosure with a towel before opening.

2. After each day of diving, it is advisable to have the main O-ring in the front

part of the enclosure removed from its groove and inspected for damage. Also

check that the O-ring retains its original circular shape; never stretch the O-

ring excessively or remove it with a sharp object.

3. The O-ring groove should be cleaned to ensure it is free from any salt deposit

or foreign material; lightly coat the O-ring with the provided lubricant before

reinstalling it in the groove.

4. A damaged O-ring should be discarded immediately and replaced only with

one that is provided by Mantis.

5. Replace the tow main O-rings and three dome O-rings annually.

6. It is recommended that you ship the enclosure to the factory or our distributor

for a complete overhaul every year or after every 200 dives.

RECOMMENDED CAMERA SETTINGS

While lighting conditions vary widely underwater, tests suggest that setting white

balance manually to 6500, limiting ISO to 400 and shooting with iLog switched off is

the best starting point for good results. We encourage users to experiment in their

local environment, especially if using artificial light.
