Disclaimers

LIABILITY DISCLAIMER

As is true of every device of diving equipment, underwater navigation systems and other underwater

equipment, the Underwater Digital Interface TM (UDI-28TM) abilities are not limitless. There are certain

limitations and restrictions of which you must be aware and certain precautions you must take when using

the UDI-28TM. Please read carefully all warnings in this document and disclaimers in each specific chapter

of the user manual.

The UDI-28TM is a computation hardware device combined with software applications that implements a

digital compass, depth measurements, navigation or tracking after acoustical signals, text messages,

gauge mode computations and alert signal communication. The UDI-28TM combines all these applications

in one unit.

The UDI-28TM is not a primary device but only an aid to send and receive text messages, to be used as

an aid in navigation or tracking after an acoustical signal, as an aid for digital compass and as an aid to

send and receive emergency signals. The UDI-28TM is not a device of life support gear. As such, it

is unlikely that you will be hurt by the instrument itself any more than you might be hurt by any other

object of similar shape, size and weight. The main danger in the use of UDI-28TM over-reliance on the

information it provides. As an electronic system it might fail spontaneously and unexpectedly due to

component, batteries or software failure. As an acoustical device based system, it can fail at any time due

to changing environmental (acoustic) conditions or internal damages of the acoustical antenna.

By purchasing or using the UDI-28TM system, it is agreed and understood that in no event will Underwater

Technologies Center Ltd (UTC) or any of their representatives be held liable for any personal injuries or

death or damages to property resulting from its operation, or for any other damages whether direct,

indirect, or consequential even if UTC has been advised of such actual or potential damages. UTC products

are authorized for use only by certified, professional divers who have maintained a sufficient level of

knowledge and high-skill proficiency through a combination of formal training, ongoing study and

experience. The user must understand that the product is liable to sudden failure.

Underwater operations are inherently dangerous, and proper safety procedures demand that you never

rely solely on just the UDI-28TM or any other single instrument, method or mechanism for human

safety or the safety of property.

REMEMBER - YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY.

BOTTOM TIMER COMPUTER DISCLAIMER

As you probably know and it is true for every device of diving equipment, and other underwater equipment,

the Underwater Digital Interface TM (UDI-28TM) abilities are not limitless. There are certain limitations and

restrictions of which you must be aware and certain precautions you must take when using the UDI-28TM

as a Bottom Timer instrument. Please read carefully all warnings in this chapter and this disclaimer.

The UDI-28TM is a computation hardware device combined with software ("SOFTWARE") applications.

The Bottom Timer is implemented with software and sensors (such as digital depth sensor and related

electronic components).

The UDI-28TM is not a primary device but only an aid to calculate along the dive the time and depth. The

UDI-28TM is not a device of life support gear and should not be used as a device for life

support.

Bottom Timer - Time and depth are presented on the screen only for assistance, thus the diver should

take into considerations that he/she must use a diving computer or diving tables.

The main danger in the use of UDI-28TM is over reliance on the information provided by it. As lies in an

electronic system it might fail spontaneously and unexpectedly due to component, batteries, incorrect

charging or software failure. In addition the UDI-28™ also contains acoustical functions; hence, as an

acoustical device, it can fail at any time due to changing environmental (acoustic) conditions.

Underwater operations are inherently dangerous, and proper safety procedures demand that you never

rely solely on just the UDI-28TM or any other single instrument, method or mechanism for human

safety or the safety of property.

BATTERIES DISCLAIMER

Lithium Ion Batteries can catch on fire. The UDI-28™ uses Lithium Ion batteries; therefore it should NOT

be left unattended while being charged as THEY CAN CATCH ON FIRE. Proper precautions should be taken

before charging Lithium ion batteries such as having a fire extinguisher ready and placing the batteries in

a fire safe container.

THE UDI-28™ IS NOT A TOY AND SHOULD BE HANDLED WITH GREAT CARE.

Lithium Polymer Charging, Handling, Safety Information

Charging:

Lithium Polymer and Lithium Ion batteries have specific charging requirements and ONLY the chargers

rated for these cells may be used. The best charger for the UDI-28™ is provided in the pack that you

purchased. Other chargers may alter the settings and can damage cells or cause a fire due to over-voltage

charging of cells. We recommend that you use only the charger that was provided with the UDI-28.

Lithium Polymer Lithium Ion cells are a tremendous advance in battery technology for electronic devices.

However, due to the chemistry of lithium cells, there is a possibility of fire if charging is not properly done.

It is unavoidable due to the nature of lithium itself. This is no different from many things we use in daily

life –knives, kitchen cleaners, automobiles, for a few examples –which are inherently dangerous, but

which can be used very safely by adhering to simple rules and precautions.

Care should be taken to charge on a fireproof surface, such as brick or in a hot (warm) environment.

Do not charge the UDI-28™ when lying on an ignitable surface. If you left the UDI-28™ in a warm

environment or open to sun light, DO NOT CHARGE IT, wait until it will be cooled to a temperature of less

than 30 centigrade. Do not charge batteries near flammable items or liquids

Keep a dry fire extinguisher nearby - or a large bucket of dry sand, which is a cheap and effective

extinguisher. Do not charge inside an automobile, especially while driving.

The UDI-28™ should NEVER be left unattended while charging.

Handling Cautions:

New cells may have a high initial charge, and care must always be taken to insure that the cap of the

UDI-28™ is completely sealed. DO NOT REPLACE BATTERIES. If the batteries performances are low,

please send it to the authorized dealer for repair or replacement.

Charging cycles:

The Batteries should work in good condition for approximately 500 charging cycles. We strongly

recommend that every year you'll send the UDI-28™ for batteries test in order to measure their stability

and charging cycles. Please remember, every charging cycle shorten the batteries lifetime and there is an

ageing process with the Lithium chemistry, thus, it is important to safely dive with batteries that will enable

you to complete the dive.

COMPASS DISCLAIMER

The UDI-28 contains 3-D Magneto Impedance sensor. Combined with software, it generates the North

magnetic direction. Common sense must be used at all times when navigating, therefore it should only be

considered as aids to navigation. The UTC' policy of continuous improvement may result in changes to

product specification without prior notice. It is advised to visit www.utc-digital.com from time to time and

to download updates for new algorithm and compensation factors for this sensor.

This compass is intended for professional dive use only; It should not be used for industrial or professional

measurements. The compass' accuracy is highly dependent on the environment, for example, soft or hard

metal will highly alter the real measurement. Thus, it is advised not to use the compass in the vicinity of

any metals. UTC does not assume any responsibility for losses or claims by third parties that might arise

through the use of this compass.

PRESET LISTS DISCLAIMER - TABLE TAG

Please ensure that prior to any dive, all UDI-28™ devices and boat units, in the same network, include

the same user list and messages list. Text messaging communications will only function properly if those

lists are identical.

To ensure that the lists are identical, each UDI-28™ has a Table Tag value, which is a unique code for

each specific UDI-28™ lists.

Make sure that each UDI-28™ device and boat unit has the same Table Tag value.

The Table Tag value is displayed in the About UDI screen.

OPERATION, RANGE AND CONFLICT

UTC provides communication means by using different configurations. Please note that a SYSTEM that

generates two Networks (i.e., NET 1 and 2) includes at a minimum, two U28 wrist units or one wrist U28

unit and a boat units. Each U28 is capable to receive signals from up to 1000m (depending on sea and

environmental conditions). Therefore, it is critical to properly define the lists of users and messages so

two different SYSTEMS will not intersect or coincide. In order to eliminate such event, all U28 that belong

to a SYSTEM must use the same table tag value. It is advised to check if other SYSTEM already exist in

the same diving area. If by mistake, in the same area (i.e. a radius of 1000meter), two SYSTEMS operate,

then there is a chance that mistaken messages (wrong message that belong to other system or characters

that have no meaning) will be received by the end user.

Notwithstanding anything herein to the contrary, the purchaser and/or user of the UDI-28TM system shall

not obtain any intellectual property right in any the UDI-28TM system or any part thereof, other than the

limited right to use it. The purchaser and/or user of the UDI-28TM system shall not have, and shall not

acquire, in any way, any intellectual property right in the UDI-28TM system. The UDI-28TM system shall

Introduction

Congratulations on your purchase of the UTC –Underwater Digital Interface 28 System.

UDI-28™ is a device that contains several functions used for diver safety, communication and

computation. Throughout this manual we will use the term UDI-28™instead of Underwater Digital

Interface (UDI-28) System. UDI-28™ is a device that contains several functions that were implemented

to increase safety, enable underwater communication and reliable computation. The UDI-28™version

was derived from the celebrated UDI-14™while taking into consideration years of experience, feedback

from users, field measurements and specific requirements by professional organizations. This version

supports extended number of messages, two large networks, state of the art error corrections code that

increases communication reliability, extended range (without extending the power) for communication,

high capacity batteries, seamless connection process to other systems (for example Passive Acoustical

Diving Radar), OLED, enhanced compass, new acoustical antenna with improved performances, support

for different languages and more. The company is grateful to the so many users and organizations that

contributed for this version.

The system consists of the UDI-28™ diving unit, an optional UDI-28™ PRO boat unit with an active

antenna, and the UDI28-MANAGER PC software. Each item can be purchase separately.

The UDI-28™ contains the following functions:

Text messages communication device

SOS signal transmission and reception

Navigation unit and homing device

Dive Information

Compass

The UDI28-MANAGER PC software can be used in conjunction with only the UDI-28™ to be used to

update text message and names (users) lists and groups and to update the firmware.

The UDI-28™ text messaging system links divers through transmission of pre-set messages with ease

and reliability. Depending on environmental conditions, it is possible to receive signals from up to 1000

meters.

Upon receiving a message signal, the UDI-28™ unit sounds an audible alert and lights up to show the

message (if these features were enabled).

The SOS signal can be activated by a diver in distress, or remotely by any diver who suspects that his

buddy is in distress. Upon activation of an SOS signal, the UDI-28™ transmits information required to

locate the SOS sender.

Each UDI-28™ includes a homing device to help the diver locate other divers or the dive boat.

The UDI-28™ can be worn on the lower arm or attached to the Buoyancy Compensator (BC).

The UDI-28™ permits a diver to communicate with any other diver in the network without distractions

or potential discomforts.

Safety

Read and understand this user guide prior to using the UDI-28. We strongly recommend that prior to

using in in real environment you will gain experience with the device.

Pay close attention to all cautions and warnings listed. Make sure that you fully

understand the use, displays and limitations of the UDI-28™ prior to diving. Improper

use of this device may cause a diver to commit actions that could lead to serious injury

or death.

The UDI-28™ has a battery saving mode. After the UDI-28™ unit is turned on:

If no button is pressed on the UDI-28™ or 10 minutes, the UDI-28™ goes to standby, and the

screen displays the word Standby.

After 60 minutes of no activity, the UDI-28™ turns off.

The UDI-28™ unit contains a water sensor. When the UDI-28™ unit that has been turned on or is in

standby comes in contact with water, the bottom timer becomes active.

A dive is considered if the UDI-28™ is at a depth of 2 meters for at least 10 seconds.

Before every dive

To ensure your safe use of the UDI-28™ before every dive, you must check:

UDI-28™ battery is charged

The preset messages list and the users list (names) in the dive group are the same. This

means that the same table tag is same in all devices in the dive group.

The network used between you and your buddy or group.

Check communications by sending a message to your buddy and receiving a message back.
