PRECAUTIONS
• A water-tight test without the monitor inside the housing is highly recommended when
using the system for the first time and after the changing of port and O-ring(s).
• Do not use lubricants from other brands with the silicone rubber O-ring on this housing,
only use the lubricant provided by NAUTICAM.
• Discontinue use immediately should you notice any leakage.
• Store the housing in a robust, shock-proof container during transportation; avoid
transporting with any equipment, such as a camera, inside the housing.
• When travelling by air, do not close the housing as this may lead to a pressure difference
between the atmosphere and inside the housing.
• Care must be taken when opening the housing, as pressure may build up inside the
housing which increases the opening force.

8
• 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 housing and the monitor 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 distributors for service, unauthorized
disassembling and/or modifications could result in malfunction or leakage.

OPENING AND LOCKING THE HOUSING
To open the housing:
1. Press the housing lock safety
button.
2. Turn the housing lock anti-
clockwise for 270°, until the lock
reaches the “Open” position as
shown.

13
To lock the housing:
3. Close the housing while the
housing lock is in the “Open”
position.
4. Turn the housing lock clockwise
for 270°, until the lock reaches
the “lock” position as shown.
Confirm that the white indicator
line on the safety button is
visible.

PREPARATION OF THE HOUSING
1. After verifying that the main O-ring is in
good condition, lightly coat it with the
lubricant provided.
2. Make sure the O-ring groove located in
the front part of the housing is free from
any foreign material; the groove can be
cleaned with the aid of a microfiber cloth.
3. Place the main O-ring into the groove,
first at the corners, then the whole
perimeter.
4. Setting up the moisture alarm:
1. Install the CR2032 battery
provided into the battery
compartment on the circuit
board inside the front part of the
housing.

15
2. Switch the alarm on. The LED
light will flash blue once and turn
blue for five seconds indicating
the battery is normal. Then it
goes into flashing blue light
standby mode.
3. Test the alarm by connecting the
two wires near the bottom of the
housing with a damp cotton bud;
the alarm should start giving out a
repeating “beep” sound along
with a flashing red light. The
“beep” sound and the light should
keep on going for 5 seconds after
the removal of the damp cotton
bud.

16
To build up vacuum:
1. Remove the vacuum valve cap.
2. Make sure the vacuum release
ring is at its closed position by
turning it clockwise until it
cannot go any further.
3. After the target vacuum level is
reached, i.e. steady green light. It is
recommended to leave the housing for
at least 20mins to ensure it is sealed. If
the LED light changes from steady
green light to rapidly flashing yellow
light, that means there is a leakage and
please check every o-ring and conduct
the vacuum test again.
Caution: Please DO NOT attempt to go
over the designated vacuum level, i.e.
stop pumping when the LED turn green.
Excessive vacuum level may lead to the
malfunctioning of the camera and lens.

Seal

17
Attention: Although the vacuum indicator
is designed to compensate for a certain
amount of temperature variation, it is
recommended to conduct the vacuum test
in an environment where the temperature
is stable.
4. Please ensure that the cap is attached
back to the vacuum valve before going
underwater.
5. Vacuum can be released by turning the
vacuum release ring anti-clockwise.
