GENERAL INSTRUCTIONS AND SAFETY STANDARDS.

IMPORTANT: It is important to read the instructions for safety reasons and to learn how to use this device

in the best way. Carefully read this user manual, including the safety measures sections. Make sure you

perfectly understand the use, functions and limits of the device before using it! DO NOT use the device

without having read every part of this instructions booklet

IMPORTANT: The safety of free diving depends on the rational capacity of each of us to develop the

theoretical and practical knowledge with common sense and prudence in order to avoid accidents. This

device must therefore only be considered an aid to free diving for people carefully prepared to the risks this

activity entails. It must be used then, only and exclusively, when you have a complete theoretical and

practical training on the techniques of free diving and its dangers.

DANGER: NO UNDERWATER COMPUTER IS ABLE TO PREVENT ANY RISK OF SYNCOPE OR THE

TARAVANA SYNDROME. IT MUST BE WELL CLEAR THAT AN UNDERWATER COMPUTER CANNOT

AND HAS NO INTENTION TO REDUCE THE RISK OF SYNCOPE OR THE TARAVANA SYNDROME.

THE COMPUTER, IN FACT, SIMPLY INDICATES THE DIVING AND SURFACE TIME, THE DEPTH AND

THE RELATIONSHIP BETWEEN THEM. THE INFORMATION THAT IS PROVIDED BY THE

UNDERWATER COMPUTER IS SIMPLE DATA THAT BECOME SAFETY INFORMATION ONLY AND

EXCLUSIVELY ONCE EXAMINED AND PROCESSED BY THE HUMAN MIND. SO IT IS

RECOMMENDED TO CARRY OUT A SOLID AND DEEP THEORETICAL PREPARATION.

IMPORTANT: This device must be used only by certified divers: no computer can, in fact, replace proper

underwater training. Please remember that a diving safety is only guaranteed by a correct preparation.

IMPORTANT: Drake computer by Cressi is designed for sport diving only and not for

professional use.

IMPORTANT: Before using the computer, please check the battery life status and the indications on the

display. DO NOT dive if these indications are not perfectly clear and, especially, if the battery is low.

IMPORTANT: Do not go into the water if the glass has cracks, chips or other. If the computer has been hit

in the glass area, or the edges of it, it is recommended not to enter into the water and take it to a CRESSI

authorised service centre to check the sealing.

DANGER: Before and air travel or altitude travel it is important not to perform heavy diving sessions at a

fast pace in the past 48 hours.

IMPORTANT: Before diving, check the device parameter settings.

IMPORTANT: Deep diving is a risky discipline and must be practice safely with a lot of practical and

theoretical training. It is therefore important to obtain a patent at a certified diving school. It is

recommended to be fully aware of its limitations and to practice this discipline within them. It is

recommended to never dive alone and always be followed by a partner ready to intervene if necessary.

IMPORTANT: Currently, there is no validated scientific literature that tells perfectly the causes of Taravana

syndrome. It is therefore important for your health not to dive in deep diving with a rapid pace for several

hours associated with short surface intervals, not to immerse in health conditions that are not perfectly

regular and always to remain hydrated and with a regular supply of energy.

REMARK: in case of air travel, the device must be stored in the pressurised cabin.

As a result of technological advancements, Cressi reserves the right to modify the device without prior

notification.

Introduction.

The watch computer Drake by Cressi is a recreational advanced tool. It will provide all the necessary

information as regards depth, dive times, possible need of decompression, descent and ascent rate and all

the surface intervals between dives. It also provides average data for each session and a separate and

special counter instantly shows the relationship between surface time and diving time. This information is

shown on the device's special display that allows an easy and direct "dialogue" between the diver and the

computer, ensuring a clear understanding of all the data needed at any given time and a perfect readability

in any situation. The computer is provided with clock, a chronograph and calendar and a versatile dive

memory (logbook). Drake operating system allows the adoption of four specific programs dedicated to free

diving and its various functions. In fact, deep diving, to meet any needs, can be practised with the two

programs called FREE and PRO, the static diving has the STATIC program and the dynamic diving has the

DYNAMIC program. Additionally, the device may be set by the user for either metric (m-ºC) or feet system

(ft- ºF). The Drake underwater watch computer can be connected to a personal computer by means of the

Cressi interface (accessory) and the related software (accessory). It is very important to carefully read this

user manual and to perfectly understand the meaning, otherwise serious damage can be caused to your

health. This manual is intended to guide the user to comprehend all the functions of the computer before

using it in diving. The Drake watch computer by Cressi is always on in the watch function and to pass to

underwater computer press and hold the MODE push-buttons or slide to DIVE menu. In the underwater

computer function, the display shows the PRE DIVE mode and the different functions are always set by

means of the push-buttons, as seen below.

In order to understand all the computer's functions and their meaning, the manual is divided into six main

chapters, dealing with every possible use:

1 - General instructions and safety standards 2 - Computer control

3 - Programs

4 - Alarms and settings

5 - Logbook and System

6 - Care and maintenance

COMPUTER CONTROL

HOW THE DRAKE WATCH COMPUTER WORKS - CLOCK

FUNCTION

Drake has a very intuitive display, which "accompanies" the diver during any operation and four push-

buttons with which it is possible to control the device: two upper (LIGHT and MODE) and two lower (UP

and DOWN).

PUSH-BUTTONS FUNCTIONS

Each push-button has a precise function which is described below.

LIGHT push-button: This push-button is used to light the display to quickly pass the programs FREE and

PRO or vice versa, and to turn off the device.

MODE push-button: This push-button is used to enter into the different menus or to confirm any

information. Pressing can be short or long. In the clock function, long pressing of 4 seconds allows

accessing to the underwater computer.

UP push-button: This push-button is used to scroll through the different menus and to set adjustments in

ascending order.

DOWN push-button: This push-button is used to scroll through the menu and to set adjustments in

descending order.

The displays that characterise the clock function are five:

- The first shows a time indication in the central area.

- The second one, besides the main time, shows the secondary time in the lower area. The date in the left

upper area and the seconds in the right upper area.

- The third one is the CHRONO display: Indicating that from this menu, it is possible to access to the

chronograph.

- The fourth one is the SET TIME display: Indicating that from this menu it is possible to access to the

adjustment of time, the secondary time, alarm, date and 12/24 hour. In this menu with the SWAP function,

it is also possible to exchange the main time with the secondary time zone and vice versa.

- The fifth one is the DIVE display: Indicating that from this menu it is possible to access the underwater

computer.

TURNING OFF THE DEVICE

To reduce battery consumption when not in use, Drake can be turned off by pressing the LIGHT push-

button for 5 seconds. Switching off will cause the loss of TIME and DATE.

CHRONOGRAPH

To access the chronograph press the UP or DOWN push-button up to the CHRONO menu down in the

display, then press MODE. CHRONO disappear to give way to the counter. To activate the chronograph,

press the UP push-button.

If split times are necessary, press the DOWN push-button (upper left, the message L1,2, ... 20 appears

and the chronograph time will indicate the split time for three seconds and then go back to counting). It is

possible to store up to 20 split times. While the chronograph is activated, at the upper right, the "LAP

TIME" will be also activated that detects the time between a split time and the other. It starts from zero

every time the split time DOWN push-button is pressed. Stop counting by pressing the UP push-button (the

message stop appears at the upper left). The split times will be displayed by pressing the DOWN push-

button. Zero setting is carried out by pressing and holding the UP push-button. To exit the CHRONO

function simply hold the MODE push-button for a few seconds until the acoustic signal.

REMARK: To store exact information in the computer logbook, remember to check for correct time and

data settings.

SWAP function: swap the main time T1 with the secondary time T2.

When travelling, it is necessary to store data of the computer using the time zone of the place but at the

same time it is possible to also see the time at the place of origin. This need is strongly felt especially by

those who go several times to the same foreign country.

The SWAP function allows the exchange of times T1 (main) and T2 (secondary) so the computer records

our dives in the foreign time and at the same time it is possible to keep aware of our time of origin.

To activate this function, press the UP button until "T1" or "T2" flash, and then press the Mode button.

"SWAP" will appear on the display to confirm that the time has been changed. Hold down the Mode button

for a few seconds until hearing an acoustic signal to confirm the exit from the menu. Keep pressing and

holding the Mode button to return to the main menu (after another acoustic signal) Alternatively, after the

last time the buttons are pressed, the computer will modify the automatic setting by issuing an acoustic

signal to return then to the main screen, and then it will automatically shut down.

pressed, the computer will modify the automatic setting by issuing an acoustic signal to return then to the

main screen, and then it will automatically shut down.

NB: Drake is set by default with the FREE program and alarms off.

FREE PROGRAM.

This program has been designed to provide the main data necessary for deep diving. Its special display

shows in the central part the most important data of that moment, alternating the depth (during the dive)

and the recovery time (as soon as it is on the surface). Its peculiarity is that is easy to use and the visibility

of the important data which are always in the centre of the display. It is a program designed for those

dedicated to free diving without the need to conduct a comprehensive analysis of its performance. Very

suitable for underwater fishermen. Perfect for snorkelling and for those who practice intensively the

discipline of sea-running or advanced snorkelling where you swim along the coast intensely alternating

dives of deep diving.

When the FREE program is set on the display, the following information appears:

On surface.

- At the top left of the display: Maximum depth reached during the last dive.

- At the top right: During the last dive.

- At the centre: Surface or recovery time.

- By scrolling with the UP or DOWN buttons down in succession: time, number of diving and minimum

water temperature, Recommended Recovery Time (recovery time calculated based on the TR-Time Ratio

pre-set by the user).

When diving.

- At the top left: Maximum depth reached.

- At the top right: Diving time.

- At the centre: Current depth.

Always visible:

- Sea water or fresh water setting icon.

- Acoustic alarms icon activated.

If you want to have more information about your dives, once you set the FREE program you can

immediately access "on-fly" to the PRO program simply by pressing the LIGHT button for a few seconds

(see PRO program).

How to use the FREE program.

Once in the program just dive and Drake will automatically display the data andwill start various counts. So

it will be for the entire session of deep diving. On the surface to displaythe information available just press

the UP or DOWN button. In the case of passage to programs STATIC or DYNAMIC Drake will close the

current session.

PRO PROGRAM.

Program for deep diving very advanced and complete that analyses in detail the performance of the diver

while providing useful information for his safety. In fact, a special indicator called Time Ratio TR constantly

scans the diving time and the recovery time providing instantly the relationship between them, relatively at

the last dive carried out and relatively at the average dives and recoveries of the session in place (since

the start of the day until that moment). All this is to inform the diver in detail about one of the most mportant

causes of the Taravana syndrome and so the too low relationship between the recovery time and the diving

time. With this important indication, the diver will have the possibility to carry out the subsequent dive once

the Time Ratio TR indicates a value which he considers safe. The display shows the data main in static

screens so as to facilitate the reading of large amount of information available. In the bottom, it is possible

to scroll through the secondary data and leave the most appropriate to the type of performance carrying

out. It is an ideal program for the advanced diver who makes deep dives and wants to improve his

performance for competitive purpose. It is also indicated for deep underwater fishing.

When the PRO program is set, the following information appears on the display:

On surface.

- At the top left: Instant Time Ratio (relationship between surface time and the duration of previous diving)

- At the top right: Surface or recovery time.

- At the centre: Maximum depth and duration of last diving.

Scrolling with UP or DOWN buttons downward: time, number of diving and minimum water temperature,

Recommended Recovery Time (recovery time calculated based on the TR-Time Ratio pre-set by the user),

descent time, ascent time, average descent speed, average ascent speed, total average speed.

- Scrolling with UP or DOWN buttons at the centre: total diving time and total surface time.

- Scrolling with UP or DOWN buttons in the complete display: average data (from top left: average time

ratio, average recovery time, average depth, average diving time, dives per hour)

When diving.

- At left centre: Current depth.

- At right centre: Diving time. Pressing the UP or DOWN buttons:

- At the top left: Maximum depth reached.

- At the bottom, during descent: Average descent speed.

- At the bottom, during ascent: Average ascent speed (by detachment from the bottom)

Always visible:

- Sea water or fresh water setting icon.

- Acoustic alarms icon activated.

- Icon of STEP alarms set.

- Icon of self-illumination set.

If you want to change the screen of the PRO program to FREE, you can immediately access "on-fly"

simply by pressing the LIGHT button for a few seconds.

How to use the PRO program.

Once in the program just dive and Drake will automatically display the data and

will start various counts. So it will be for the entire session of deep diving. On the surface to display the

information available just press the UP or DOWN button. In the case of passage to programs STATIC or

DYNAMIC Drake will close the current session.

WARNING: Before using the Drake underwater computer, it is recommended to take a diving

course at a serious and accredited school.

WARNING: Diving is an underwater discipline that definitely is not as simple as it might seem.

Before you engage in this activity you must know in depth all the physiological, physical and

chemical aspects. It is also fundamental that you have a deep knowledge of the underwater

medical point of view.

STATIC PROGRAM.

Program for static diving dedicated to athletes who want to practice the discipline or those who

just want to train to improve their performance. Its special display shows in the central part the most

important information at that moment, alternating the diving time to the recovery time. It must be operated

manually as a standard depth is not defined for which it is considered a static diving. Some athletes are on

the water's surface while others are just a few centimetres deep. It is therefore necessary to manually

activate the chronometer at the beginning of the diving and stop it at the end so that the computer starts to

count the recovery time. The display also shows the depth. In the bottom, it is possible to scroll through the

secondary data and leave the one you want.

When the STATIC program is set, the display shows the following information:

On surface.

- At the top right: Time of last diving.

- At the top left: Current depth.

- At the centre: Surface or recovery time.

- Scrolling with UP or DOWN buttons at bottom: number of diving and water temperature, time, last

chronograph information and reset to restart and carry out a new session.

When diving.

- At the top left: Current depth.

- At the centre: diving time

- At the bottom: chronograph for the diaphragmatic contractions.

Always visible:

- Acoustic alarms icon activated.

- REPS icon activated.

How to use the STATIC program.

Once in the program, it must be operated manually by pressing the Mode button at the beginning of the

diving. After diving, and when re-emerging, to stop the time, press again the Mode button. The computer

will start to count the recovery or surface time until you press again the MODE button for subsequent

diving. Then, the time of the second diving will be counted. So on the times you want. To stop the computer

counting and start a new session, press the UP button repeatedly until the word RESET appears at the

bottom of the display. Press MODE and the computer will reset.

During diving Drake is able to measure the time, in minutes and seconds, from different times to the total

time of diving, such as the time between the diaphragmatic contractions.

WARNING: Before using the Drake underwater computer, it is recommended to take a diving

course at a serious and accredited school.

WARNING: Diving is an underwater discipline that definitely is not as simple as it might seem.

Before you engage in this activity you must know in depth all the physiological, physical and

chemical aspects. It is also fundamental that you have a deep knowledge of the underwater

medical point of view. DANGER: Before performing the test of static diving, make sure to be

followed by a person on the edge of the tank who is ready to intervene in case of need. It is also

recommended, during diving, to move a limb or a finger to ensure that the surface mate becomes

immediately aware of a possible loss of consciousness.

DYNAMIC PROGRAM.

Program dedicated to athletes who practice dynamic diving as a discipline or as training activities for the

improvement of their general performance. It is very suitable even for the sea-running or advanced

snorkelling where they swim along the coast intensely alternating dives of deep diving or not. Once in the

program, in order to operate the chronographs just dive to make the first tank diving.

When the DYNAMIC program is set, the display shows the following information:

On surface and during diving:

- At the top left: Sum of the diving time and surface time.

- At the top right: Surface time.

- At left centre: lap counters / path counters.

- At right centre: diving time.

- Scrolling with UP or DOWN buttons downward: total training and session time, time and reset function.

Always visible:

- Sea water or fresh water setting icon.

- Acoustic alarms icon activated.

How to use the DYNAMIC program

Once in the DYNAMIC program, Drake will start counting automatically as soon as you dive to make the

first tank diving. The diving time will be immediately displayed. Subsequently, as soon re-emerged, it will

count the surface time and the sum of both the times. And so on until you decide to stop or change the

session. To stop the computer counting and start a new session, press the UP button repeatedly until the

word RESET appears at the bottom of the display. Press MODE and the computer will reset.

RECOMMENDED RECOVERY TIME ALARM FOR FREE AND PRO PROGRAMS.

Underwater diving, if not performed with proper preparation (both physical and theoretical) involves risks.

One of them is to incur in the neurological syndrome of TARAVANA

which is a particular form of Decompression Illness due to several factors associated with an accumulation

of nitrogen (This syndrome is still under study and its causes are not known exactly. It is therefore

recommended to deepen your knowledge by consulting updated and current texts of underwater

medicine). It is a disease that is known since the 40s and that affected the Polynesian pearl divers (the

term TARAVANA means madness). The cause can be summed up in an intense and excessive activity of

diving with duration of at least 4/5 hours, at great depths or in the range of -12/-18m and with very short

surface intervals. To avoid this syndrome, it is recommended to make surface intervals or recovery times

much longer than the diving times, to be perfectly hydrated and always provide an appropriate energy

recovery. To help the diver to keep a proper relationship between the diving time and the recovery time,

Drake has a special function that can store the multiplier of diving time (TR Time Ratio) desired by the

underwater and display the resulting recovery time that will be indicated by the acronym RRT

(Recommended Recovery Time). For example: if the diving time is 1' and 10" and the multiplier TR is

imposed in 4, the RRT time will be 4' and 40'' (1' 10" 'x 4 = 4' 40'').

SETTING ACOUSTIC ALARMS FOR ALL THE PROGRAMS

There are diving disciplines where a sound alarm is necessary to keep higher concentration or where a

sound alarm can be more counter-productive than an aid. For these reasons, Drake allows the activation

or deactivation of the acoustic alarms according to the selected activity. Activating the acoustic alarms,

Drake will accompany each alarm previously entered with an audible signal. Otherwise Drake will eliminate

this acoustic signal to all active alarms in the current program.
