PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678), Ascent Rate Indicator (U.S. Patent no. 5,156,055), Dive Computer with Free Dive Mode
(U.S. Patent no. 8,600,701).
CE
The CE mark is used to mark conformity with the European Union EMC directive 89/336/EEC. TUSA dive instruments fulfill the required EU directives.
EN 13319 "Diving accessories - Depth gauges and combined depth and time measuring devices - Functional and safety requirements, test methods" is a
European diving depth gauge standard. The Talis is designed to comply with this standard.
DECOMPRESSION MODEL
The program within the Talis simulates the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a
limited set of data to a large range of experiences. The Talis dive computer model is based upon the latest research and experiments in decompression
theory. Still, using the Talis, just as using the Navy (or other) No Decompression Tables, is no guarantee of avoiding decompres-
sion sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body
will react to a particular dive profile.
LIMITED TWO-YEAR WARRANTY
For details, refer to the Product Warranty Registration Card provided.
Talis Watch/Dive Computers are placed in a Deep Sleep mode prior to being shipped from the factory. The intent is to extend storage life of
the Battery for up to 7 years, before the unit is initially placed in service.
In this mode, Date and Time are updated as they normally would be. However, they are not displayed. Upon waking the Talis up, the correct
Date and Pacic Time will be displayed and it will be ready to operate with full functions.
To wake the Talis up from Deep Sleep mode, simultaneously depress the upper/right (S) and lower/left (A) buttons for 2 to 3 seconds until the
display comes full ON displaying the Watch Default Time screen, then release them.

Welcome to TUSA.
Thank you for choosing the Talis !
-------------------------------------------------------------------------------------------------------------------------------
It is extremely important that you read this Owner's Manual in sequence and understand it completely
before attempting to use the Talis as a dive computer.
Remember that technology is no substitute for common sense, and a dive computer only provides the per-
son using it with data, not the knowledge to use it.
-------------------------------------------------------------------------------------------------------------------------------
CONTROL BUTTONS
The Talis features 4 Control Buttons that allow you to select mode options and access specific information. They are also used to
enter Settings, activate the Backlight, and acknowledge the Audible Alarm.
Throughout this manual they will be referred to as the M, S, L, and A buttons (Fig. 1).
• Upper/Left - Mode (M) button
• Upper/Right - Select (S) button
• Lower/Right - Light (L) button
• Lower/Left - Advance (A) button
OPERATING MODE STRUCTURE
Unless it is operating in Dive Computer mode, the Talis will be On in the Watch Default Time (home time) mode (Fig. 1), like a
standard watch, until the mode is changed.
The M button is used to access other selections that include Alternate data, Countdown Timer, Chronograph, and Daily Alarm. It
is also used to revert back to the Watch Default Time display and access Dive Computer Modes.
The screens of the Main Modes and Sub Modes will remain on display until a button is pressed to access another screen or
Mode, activate a sequence, or for 2 minutes if no button is pressed. The Chronograph remains on display as long as it is running
unless another Mode is accessed.
When Wet Activation is set On, the Talis will enter the selected Dive Mode upon descent to 5 FT (feet)/1.5 M (meters) for 5
seconds, regardless of what operating mode it is in.
WARNING: When Wet Activation is set OFF, the Talis must be in Dive Computer Surface Mode (NORM,
GAUG, or FREE) prior to the first dive of a new series. Commencing a dive while in Watch modes will
not activate Dive Mode unless Wet Activation is set ON.
OPERATION AS A DIVE COMPUTER
The Talis features 3 Dive Computer (DC) Operating Modes,
>> NORM (Fig. 2) is used for Air and Nitrox dives.
>> GAUG (Fig. 3) is used for dives in which Nitrogen-Oxygen calculations are not performed.
>> FREE (Fig. 4) is used for breath hold activities that do not use SCUBA.
NORM and GAUG SURF Modes allow access to Settings, Fly, Desat, Log, and History Modes.
NORM SURF also allows access to Plan Mode.
FREE SURF Mode allows access to a separate group of settings.

AUDIBLE ALARM
Most warning situations that activate the Audible Alarm while operating in NORM or GAUG Mode will sound 1 beep per second
for 10 seconds, or until the situation is corrected, or it is acknowledged by pressing and releasing the S button (less than 2
seconds). After being acknowledged and the situation corrected, the Alarm will sound again upon reentry into the warning situa-
tion, or entry into another type of warning situation.
FREE Dive Mode has its own set of Alarms which emit 3 short beeps either 1 or 3 times that cannot be acknowledged or set Off.
The Audible will not be active if it is Set OFF (a group A setting).
Situations that will activate the NORM/GAUG 10 second Alarm include -
• Descent deeper than the Max Depth Set Point selected.
• Dive Time Remaining at the Set Point selected.
• Elapsed Dive Time at the Set Point selected.
• High PO2 of 1.60 ATA or the Set Point selected for the Gas in use.
• High O2 of 300 OTU (single or daily exposure).
• Nitrogen Bar Graph at the segment Set Point selected.
• NORM/GAUG Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM) at 60 FT (18
M) and shallower.
• Entry into Decompression Mode (Deco).
• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes).
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required).
• Delayed Violation (Maximum Operating Depth of 330 FT/100 M is exceeded).
• A Gas Switch to another tank would expose the diver to PO2 greater than 1.60 ATA.
• Watch Daily Alarm reaches time set (disabled during Dive Modes).
• Watch Mode Countdown Timer reaches 0:00.
A single short beep (which cannot be disabled) is emitted for the following -
• Upon completion of a Hot Swap battery change.
• Change from Delayed to Full Violation 5 minutes after the dive.
3 short beeps (which cannot be disabled) are emitted for the following -
• NORM/GAUG Ascent Rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or 26 to 30 FPM (7.5 to 9
MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set On).
• FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive NIBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Permanent Violation) - 3 beeps 3 times.
• Free Dive Mode Countdown Timer reaches 0:00 - each 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that will
not turn off when acknowledged -
• Ascending above a required Decompression Ceiling Stop Depth for more than 5 minutes (referred to as a Delayed
Violation).
• Decompression requires a Ceiling Stop Depth of 70 FT/21 M or deeper.
• Being on the Surface for 5 minutes after a Conditional Violation.
BACKLIGHT
To activate the Backlight - press the L (lower/right) button.
• The Backlight will activate and illuminate the display for button depression time* plus the user set Duration time of 0, 5, or
10 seconds, for a maximum of 20 seconds.
(*The Backlight turns Off if the button is held depressed for more than 10 seconds.)
• Press the button again to activate as desired.
NOTE: Extensive use of the Backlight reduces Battery life. Also, the Backlight does not operate during
a Low Battery condition or when the Talis is connected to a PC or Mac.
POWER SUPPLY
The Talis uses (1) 3 volt CR2430 Lithium Battery. Used as a Dive Computer, the battery should operate normally for 1 year or
300 dive hours if 2 dives are conducted during each dive period. Voltage is checked every 2 minutes on the surface.
• If voltage of the Talis decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface display screens
(Fig. 5a) as an indication that the Battery should be changed prior to commencing a series of dives.
• If the Talis's voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the graphics CHG > BAt will
alternate (Fig. 6a) for 5 seconds, then operation will automatically revert to the Watch Default Time screen. The Talis would
then only operate in Watch modes until the Battery becomes completely depleted.
• Low Battery conditions are not displayed during dives.
• If a Low Battery Condition was not displayed prior to starting a Dive, and a Low Battery Condition occurs during the dive,
there will be sufficient Battery power remaining to maintain operation for the remainder of that dive. Fig. 6 - LOW BATTERY

BAR GRAPHS
The Talis features 2 Bar Graphs, the NiBG and ASC.
NiBG (Nitrogen Loading Bar Graph)
The NiBG (Fig. 19a) represents tissue loading of nitrogen, showing your relative no decompression or decompression status. As
your depth and elapsed dive time increase, segments will add to the NiBG, and as you ascend to shallower depths, the segments
will recede, indicating that additional no decompression time is allowed for multilevel diving.
The Nitrogen Loading Bar Graph monitors 12 different nitrogen compartments simultaneously and displays the one that is in
control of your dive. It is divided into a No Decompression (normal) zone, a Caution zone (also No Decompression), and a
Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk.
ASC (Ascent Rate Indicator)
The ASC (Fig. 19b) provides a visual representation of ascent speed (i.e., an ascent speedometer).
The segments of the ASC represent two sets of speeds which change at a reference Depth of 60 FT (18 M). Refer to the chart for
segment values.
WARNING: At depths greater than 60 FT (18 M), ascent rates should not exceed 60 FPM (18 MPM).
At depths of 60 FT (18 M) and shallower, ascent rates should not exceed 30 FPM (9 MPM).

During dives, Current Depth (Fig. 20a) and Maximum Depth (Fig. 21a) which is on an Alternate Display indicate Depths from 0
to 330 FT (100 M) in increments of 1 FT (0.1 M).
During a No Deco Safety Stop, the set Stop Depth is displayed and during Decompression, required Stop Depth is displayed.
Time
Most Time displays like Time of Day (Fig. 21b) are shown in hour:minute format (i.e., 10:26 represents 10 hours and 26 minutes.
The colon that separates hr:min (min:sec) blinks once per second when the display is indicating real time (e.g., Time of Day,
Elapsed Dive Time).
When Times are calculated projections such as Dive Time Remaining and Elapsed Dive Time (Fig. 20b/c), the colon is solid (non
blinking).
FREE Dive Mode displays Times in minute:second format.
Temperature, Elevation
Ambient Temperature and Altitude can be viewed by accessing the Watch or Dive Computer Surface Alternate screens (Fig. 22).
When above the sea level range, which extends up to 3,000 feet (915 meters), Altitude is displayed as EL (Elevation Level) from
2 up to 7.
EL2 = 3,001 to 5,000 feet (916 to 1,525 meters)
EL3 = 5,001 to 7,000 feet (1,526 to 2,135 meters)
EL4 = 7,001 to 9,000 feet (2,136 to 2,745 meters)
EL5 = 9,001 to 11,000 feet (2,746 to 3,355 meters)
EL6 = 11,001 to 13,000 feet (3,356 to 3,965 meters)

DIVE COMPUTER (DC) OPERATING MODES
The Talis features 3 DC Operating Modes -
• NORM >> for Normal Air or Nitrox dives using scuba.
• GAUG >> for scuba dives with no nitrogen/oxygen calculations.
• FREE >> for breath hold dives with no SCUBA.
SURFACE MODE
M (2 sec), while the Watch Default Time screen is displayed - to access the DC Surface Main screen.
If no other dive has been conducted within the past 24 hours, the NORM Surface Main will appear as the default display indicat-
ed by the graphic Nor (Fig. 23). If a GAUG or FREE dive has been conducted within the past 24 hours, the Surface Main screen
for that Operating Modewill be displayed.
• The GAUG and FREE Surface Main screens can be accessed by depressing M (2 sec) . Their graphics will flash indicating
that they can be selected as the Operating Dive Mode.
• To select a Mode for diving, press/release M (< 2 sec) while that graphic is flashing. When the graphic becomes solid, that
Mode is selected for the type of dives to be conducted.
• The Operating Mode selected (NORM, GAUG, or FREE) will remain on display for 2 hours until a dive is made or another
Operating Mode is selected.
At any time while operating in Surface Modes, the Talis will enter Dive Mode upon descent to 5 FT (1.5 M).
• During the 2 hour pre dive surface period, if other screens in the Watch Mode sequence are accessed, Surface Mode must
again be accessed prior to the first dive of a series (if Wet Activation is set OFF).
• When Wet Activation is set ON, the Wet Contacts will activate the selected Dive Mode regardless of what Mode the Talis is
operating in at the time of the descent.
The Talis will enter Post Dive Surface Mode following a dive upon ascent to 2 FT (0.6 M). The Surface Interval Time colon will
flash during the first 10 minutes after a NORM or GAUG dive (Fig. 24), or 1 minute after a FREE dive.
During the first 10 minutes after a dive, the Surface Main screen for the operating mode remains on display. Watch Default Time
can be viewed for 5 seconds during that period by pressing M (< 2 sec).
When the 10 minute Surface Time has elapsed, the Watch Default Time screen will replace the DC Surface Main screen which
can then be accessed by M (2 sec).
--------------------------------------------------------------------------------------------------------

NORM/GAUG SET MODES
SURF MAIN > SET GAS > SET A > SET U > Serial Number.
A & S (2 sec) - to access then step through of the sequence.
Alarms (Set A) and Utilities (Set U) set points can also be set/changed using the PC/Mac settings upload program.
Set Gas (FO2 & PO2 Alarm) entries must be made using only the push buttons.
Settings remain at the values set until they are changed, and saved, as described by the following sections.
--------------------------------------------------------------------------------------------------------
SETTING GAS FOR NITROX DIVES
For each value of FO2, the MOD (Max Operating Depth) that can be achieved for the PO2 Alarm value set, will be displayed.
When the FO2 50% Default is set On and FO2 for Gas 1 is set for a numerical value, 10 minutes on the surface after that dive,
the FO2 for Gas 1 will be displayed as 50 and further dives will be calculated based on 50% O2 for oxygen calculations and
21% O2 for Nitrogen calculations (79% Nitrogen) unless the FO2 for Gas 1 is set before the dive.
FO2 for each Gas continues to reset to the FO2 50% Default after subsequent repetitive dives until 24 hours elapse after the last
dive, or the FO2 50% Default is turned Off.
When the FO2 50% Default is set Off, the FO2 for each Gas will remain at the last settings for the remainder of that series of
repetitive dives.
The default FO2 for Gas 1 and 2 each new dive Period is AIR.
When FO2 is set for AIR, the calculations are the same as when it is set to an FO2 of 21%. When FO2 is set to AIR, it remains
set for AIR until it is set for a numerical FO2 value (21 to 100%).
When FO2 is set only to AIR, the O2 and PO2 values and/or warnings will not be displayed during the dive.
MODs affected by the PO2 value set will not be displayed when FO2 for Gas 1 is set to AIR.
Internally, the Talis keeps track of the O2 so that if FO2 for a Gas is subsequently set for a numerical value, the O2 accumulated
during previous dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives).
Once FO2 is set for a numerical value (21 to 100%) and a dive is made, the AIR option is disabled until 24 hours elapse after
the last dive. The AIR option will not be displayed in Set Gas until a full 24 hour Surface Interval has elapsed.
If the FO2 50% Default is set Off, FO2 for each Gas will remain at the values previously set until they are changed. If the FO2
50% Default is set On, FO2 will Default to 50% after the dive.
