Thank you for your selection of the TUSA IQ-1203CE Dive Computer.
◆This dive computer does not conform to
the diver watches(100m) stated in the ISO6425 and JISB7023.
Applications
This is a dive computer to support no decompression dive safely.
Solar panel generates electric power to run the dive computer.
It has multi-functions as watch, alarm, timer, stopwatch, direction
compass and angle, world time watch in the Time mode, and
surface interval time and desaturation time (DESAT time) in surface
interval. In the Dive Mode, information of water depth, water
temperature,dive time, ascent speed and decompression are
provided. When divers exceeds no decompression limit, the dive
computer givesdivers alarm with display.
It applies to Nitrox (EANx) dive too. You can set fraction of
oxygen(FO2) % per 1 % from 21% (Air) to max. 50%.
The calculation model we use for the decompression program of
the dive computer is based on the decompression theory of Dr. A.
A. Buhlmann.
Before use, you need understand how to use, all warnings and
cautions of the dive computer written on this Instruction Manual.
To avoid any serious accidents, please make sure to read and fully
understand the dive computer. If you have any questions, please
ask the shop you purchased the dive computer.
Whenever there is a thing you do not know in how to use of the
dive computer, we strongly recommend to access the web site of
TUSA and read this instruction manual well.
Understanding and using the functions of the dive computer
ensures safe dive you can enjoy.

computer from customers and any third parties.
Danger
• Make sure to understand how to use, warnings, and cautions
of this dive computer with this Instruction Manual completely
before use. Confirm that you understand how to use the dive
computer in closed water as in a pool before using in open
water.
• When using the dive computer in scuba diving, you need to take
dive training course both in learning rules and practical skills,
and obtain C card (certification card) issued by internationally
acknowledged dive training organizations beforehand. (You
can use the dive computer in the training under the guidance of
instructors of such organizations)
• When using the dive computer in Nitrox (EANx) dive, you need
to take Nitrox (EANx) dive training course and complete it
beforehand. Otherwise, do not use the dive computer in Nitrox
(EANx) dive.
Ref: EANx: Enriched Air Nitrox (commonly called Nitrox).
It is mixed gas with higher FO2% than normal compressedair
(FO2is 21%)
• If “Decompression stop violation” warning and/or “Out of
measurement range” warning are released, cancel dive for a
day and pay attentions on changes of your physical condition.
• When you notice abnormal conditions on the dive computer,
stop using it immediately and contact the shop you purchased
the dive computer.

• Check the battery power level is “H” before dive. If power
levelgets low and warning (WARNING!! BATT) is released while
dive, exit as soon as possible and recharge the dive computer.
●Even this warning is released in dive, enough power for dive
remains. Deal with the situation calmly without panic Ref.
Power Levels … P.11
• Follow the displayed warnings and messages for cautions on
the dive computer at once.
• When using the dive computer, also use other devices as
another dive computer, divers watch, and depth indicator
together as backup tool.
• The dive computer is to be used for recreational dive only.
Do not use the dive computer for any other dive.
• Never lend or share the dive computer with anyone else if
residual nitrogen still exists in the body after use of the dive
computer.
• Make sure to set FO2% in every dive. It is extremely dangerous
if FO2% in tank and in the dive computer don’ t match.
• Dot not disassemble, repair, modify, exchange the secondary
battery or conduct pressure chamber test on the dive computer
by yourself. This will be extremely dangerous since doing this
without sufficient knowledge causes malfunction.
• Check out the dive computer by yourself once a year regardless
of frequency of use. Especially, check it out definitely when you
have not used the dive computer for more than 3 months since
last dive season.

• The dive computer is applicable to the air with FO221 % and
Nitrox (EANx) gas with FO222-50%. The dive computer can not
be used with any other mixed gas.
• Each diver should be responsible in planning and conducting of
safety dive according to each diver’ s condition.
• Please try cautious dive not exceeding the displayed data in
the dive computer. The dive computer can not prevent from
developing decompression illness completely.
• The dive computer does not measure, display and control the
air pressure in tank. Use the residual air pressure indicator and
check it by yourself.
• When removing the secondary battery from the dive computer,
be careful for small children not to swallow it. Put the battery
out of reach of children. If swallowed, contact a doctor at once.
