CARE AND CLEANING
Protect your Element from shock, excessive temperatures, chemi-
cal attack, and tampering. Protect the lens against scratches
with a transparent Instrument Lens Protector. Small scratches will
naturally disappear underwater.
• Soak and rinse the Element in fresh water at the end of each
day of diving, and check to ensure that the areas around the
low pressure (depth) sensor (Fig. 61a) and button are free of
debris or obstructions.
• To dissolve salt crystals, use lukewarm water or a 50% white
vinegar/50% fresh water bath. After removal from the bath,
place the unit under gently running water and towel dry
before storing.
• Transport your unit cool, dry, and protected.
INSPECTIONS AND SERVICE
Your Element should be inspected annually by an Autho-
rized TUSA Dealer who will perform a factory prescribed func-
tion check and inspection for damage or wear. To keep the
product's warranty in effect, this inspection must be completed
one year after purchase (+/- 30 days). TUSA recommends that
you continue to have this inspection performed every year to
ensure it is working properly.
To Obtain Service
Take your Element to an Authorized TUSA Dealer.

NOTE: The procedures that follow must be closely adhered to. Damage due
to improper battery replacement is not covered by the unit's warranty.
MODULE REMOVAL FROM BOOT
If the Module is in a Console, bend the rubber Console Boot back to expose the edge of
the Module. If the Boot is flexible enough to permit, you may bend it back far enough to
scoop the Module out with your finger. Otherwise, it may be necessary to insert a blunt
screwdriver until the tip rests just underneath the Module. DO NOT pry the Module from
the Console! Slowly increase the pressure under the Module by releasing the tension on
the rubber Boot. The Module will slide up the screwdriver and exit the Console.
If the Module is in a Wrist Boot, it will be necessary to peel the lips of the Boot downward
off the Module while applying pressure from underneath, working it out slowly.
BATTERY REPLACEMENT
The Battery Compartment should only be opened in a dry and clean environment with
extreme care taken to prevent the entrance of moisture or dust.
To prevent formation of moisture in the Battery Compartment, it is recommended that the
Battery be changed in an environment equivalent to the local outdoor temperature and
humidity (e.g., do not change the Battery in an air conditioned environment, then take it
outside during a hot sunny day).
NOTE: If the old Battery can be removed and the new one inserted within 8
seconds, nitrogen and oxygen calculations and settings, will be retained for
repetitive dives.
56
Battery Hatch Removal
• Locate the Battery Compartment on the back of the Module.
• While applying steady inward pressure on the center of the
Battery Hatch, rotate the Hatch Retaining Ring 10 degrees
clockwise using a flat blade screwdriver (Fig. 62) or a
Battery Hatch Tool.
• Lift the Hatch Ring up and away from the Housing, or turn
the Module over to allow it to drop out into your hand.
• Remove the Battery Hatch.
Battery Removal
• Remove the Retaining Bar located across the lower portion of
the Battery (Fig. 63a).
• Remove the Hatch O-ring. DO NOT use tools
• Using care not to damage the Battery Contacts (Fig. 63b/c),
slide the Battery up and out of the Battery Compartment.
Inspection
• Closely check all of the sealing surfaces for any signs of
damage that might impair proper sealing.
• Inspect the Button, Lens, and Housing to ensure they are not
cracked or damaged.
• If it is necessary to clean the Battery Compartment, flush it
and all components with a solution of 50% white vinegar
and 50% fresh water. Rinse with fresh water, and allow to
dry overnight, or blow dry with a hair dryer (set at 'no heat').

WARNING: If damage or corrosion is found, return
your Element to an Authorized TUSA Dealer, and DO
NOT attempt to use it until it has received factory
prescribed service.
Battery Installation
• Slide a new 3 volt type CR2450 Lithium Battery, negative
( - ) side down into the Battery Cavity. Slide it in from the
right side and ensure that it slides under the contact clip on
the left rim of the cavity (Fig. 64).
• Orient the Retaining Bar across the lower portion of the
Battery and carefully push it down into position (Fig. 65).
Battery Hatch and Hatch Retaining Ring Installation
• Replace the Hatch O-ring with a new one which must be a
genuine TUSA part.
• Lightly lubricate the new Hatch O-ring with silicone grease
and place it on the inner rim of the Battery Hatch (Fig. 66).
Ensure that it is evenly seated.
• Slide the Hatch Retaining Ring, top portion first (small open-
ing), onto your thumb.
• Carefully place the Battery Hatch (with O-ring) into position
on the rim of the Battery Compartment, then press it evenly
and completely down into place with your same thumb.

• Maintain the Battery Hatch securely in place and, using your
other hand, slide the Retaining Ring down off your thumb
and into position around the Battery Compartment.
• The tabs on the Retaining Ring fit down into the two slots
located at the 2 and 8 o'clock positions.
• Using your fingers, turn the Ring counter clockwise 5 de-
grees until the tabs engage (Fig. 67), then tighten it 5 more
degrees by turning it counter clockwise using the Battery
Hatch Tool (Fig. 68).
• While tightening the Retaining Ring, exert continuous inward
pressure on it until it is secured in the proper position. A
small symbol located on the Ring should be aligned with the
Locked symbol located on the Housing (Fig. 68a)
Inspection
• Activate the unit and watch carefully as it performs a full
diagnostic and battery check, and enters Surface Mode.
• Observe the LCD display to ensure it is consistently clear and
sharp in contrast throughout the screen.
WARNING: If there are any portions of the display
missing or appearing dim, or if a Low Battery condi-
tion is indicated, return the Element to an Authorized
TUSA Dealer for a complete evaluation before at-
tempting to use it.

RETURNING THE MODULE TO BOOT
• If the Boot was fitted with a Spacer and it was previously removed, replace the
Spacer into the Boot.
• Orient the Module over the opening in the Boot, and dip the bottom edge into it while
pressing the top edge with the palm of your hand. Stop pressing when the bottom
edge of the Module has just entered the Boot.
• Correct the alignment of the Module as needed so that it is straight.
• Press the Module completely into place with your thumbs, watching the alignment,
until it snaps into place.
Responsible
UNEXPECTED LOSS OF DISPLAYED INFORMATION
If your Element stops working for any reason, it is important that you have anticipated this
possibility and are prepared for it. This is an important reason for not pushing
the No Decompression and Oxygen Limits, and a critical reason to avoid
entering Decompression.
If you dive in situations where your trip would be ruined or your safety would be jeopar-
dized by losing the use of your Element, a backup instrument system is highly recom-
mended.
60
ALTITUDE COMPENSATION
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems
and ambient temperature also affect barometric pressures. Consequently, depth reading
instruments that do not compensate for the decrease in ambient pressure indicate depth
readings shallower than the depth they are actually at.
The Element automatically compensates for decreased ambient pressures for Altitudes
between 3,001 feet (916 meters) and 14,000 feet (4,270 meters). Its program contains a
high altitude algorithm that reduces no decompression and oxygen exposure limits to add
a larger zone of caution.
The Element senses ambient pressure when it is activated, every 15 minutes while it is
activated, or every 30 minutes when it is not activated. At an Altitude of 3,001 feet (916
meters ), it will automatically recalibrate itself to measure depth in meters (feet) of fresh
water rather than feet (meters) of sea water. It will then readjust the no decompression
and oxygen limits at additional intervals of 1,000 feet (305 meters). When returning to
lower Altitudes, diving should not be conducted until the unit automatically clears of any
residual nitrogen and oxygen loading and resets to operate at the new lower Altitude.
WARNING: The Element will not sense ambient pressures or provide Altitude
compensation when it is wet. DO NOT dive at any different Altitude until the
unit shuts off and is reactivated at the new Altitude.
If the unit is activated at elevations higher than 14,000 feet (4,270 meters), it
will perform a diagnostic check followed by immediate shutdown.
