Thank you for choosing the TUSA TC1(IQ1301) Dive Computer.

◆This dive computer does not conform to Dive watches (100m) stated in the

ISO6425 and JISB7023.

Applications

This is a dive computer to support no decompression diving safely. The TUSA

TC1(IQ1301) functions as a watch, alarm, timer, stopwatch. In Dive Mode,

information of water depth, water temperature, dive time, ascent rate and

decompression are provided. When divers exceed no decompression limits, the

dive computer will show audible and visual alarms.

Comprehensive accelerated decompression is possible because each fraction of

oxygen (O2) % can be set from 21% to 56% in 1% increments.

The calculation model used for decompression is based on the decompression

theory of Dr. A. Buhlmann (ZHL-16C).

Before use, you need understand all warnings and cautions of the dive computer

written in this Instruction Manual. To avoid any serious accidents, please make

sure to read and fully understand the dive computer and its functions.

Understanding and using the functions of the dive computer ensures your safe

diving.

Safety Precautions

Please read the following before use.

TUSA shall assume no responsibility on damage, lost profit and/or any claims

caused in use or by malfunctions of this dive computer from customers and any

third parties.

Danger

• Make sure you understand how to use the warnings, and cautions of this dive

computer within this Instruction Manual before use.

• Before using the dive computer for scuba diving, you must first complete a dive

training course, and obtain a certification card issued by an internationally

acknowledged dive training organization.

• Before using the dive computer with Enriched Air Nitrox (EANx), you must first

receive certification in an Enriched Air Nitrox (EANx) dive training course.

(EANx: Enriched Air Nitrox (commonly called Nitrox). Contains mixed gas with

higher O2% than normal compressed air (O2is 21%) )

• If “Decompression stop violation” warning and/or “Out of measurement range”

warning is activated, discontinue diving. Monitor your health and seek medical

attention if necessary.

• When you notice abnormal conditions on the dive computer, immediately stop

using it and contact your retailer or TUSA for assistance.

Page 4

• Always follow the display warnings, messages, and cautions on the dive

computer.

• When using dive computers, it is recommended to use a back-up dive

computer, dive watch, and/or depth and pressure gauge.

• This dive computer is to be used for recreational diving only. Do not use this

dive computer for any other type of diving.

• Never lend or share dive computers as residual nitrogen may still exist in the

body after use of the dive computer.

• Make sure to set the O2% for every dive. It is extremely dangerous if the O2% in

the scuba cylinder does not match the computer setting.

• Dot not disassemble, attempt repair, modify, exchange the battery or conduct

pressure chamber tests on the dive computer.

• Before any dive, always check your dive computer status, complete all related

settings and check for sufficient battery power.

• Have your dive computer checked by a TUSA technician once a year or before

any major trip.

• The dive computer may be set to air with O221 % and Nitrox (EANx) gas with

O222-56%. The dive computer cannot be used with any other mixed gas type.

• Divers should be responsible in planning safe diving while considering current

conditions.

• Dive with caution. DO not exceed the computers limits. Exceeding the

computers limits may put you at risk of decompression sickness (DCS).

• The dive computer does not measure or display the tank air pressure. Use a

pressure gauge to monitor your air consumption.

• Do not remove the battery from the dive computer. Return the unit to the

manufacturer for service of the battery if necessary.

• The battery may pose as a choking hazard. Keep out of reach of children.
