WARNING
Diving is an adventurous sport and should not be
undertaken without receiving the necessary training
from a recognised training agency.

WARNING!
Even if your dive computer or PC generated software allows for less
conservatism and a reduction in decompression times this should not be
arbitrarily undertaken without first researching data available from other
divers/agencies, conducting controlled trials and understanding that you may
be undertaking a level of experimentation in order to adjust the algorithm for
your specific needs.
No decompression algorithms can give a guaranteed safe decompression. It is
your responsibility to be trained, dive safely, carry backup tables and
instrumentation and compare any decompression profiles generated by the
DG05 computer and their associated decompression software against established
diving tables with which you are happy and/or accept that you may be
conducting experimental decompressions.
High pressure gas sensors and PO2 monitors when connected to DG05 dive
computer product provide for the additional monitoring of key safety data. It is
important that in the unlikely event of failure, back-up instrumentation is
carried.
In the case of a rebreather, the unit should be capable of monitoring the PO2 in
addition to using information from the DG05 computer.

Battery
The DG05 is fitted with a rechargeable Lithium-ion battery. A multi-voltage charger
is supplied, that will recharge a completely flat battery in approximately 3 hours.
The battery level is shown in percentage on the main front dry screen. A full battery
will give the approximate performance below:
Note all times are
approximate
DG05 -
4.2v
Lithium
Ion
Sleep no use
6 months
On time with backlight on
10 hours
On time with backlight off
20 hours
On time with torch and
backlight on
8 hours
Power usage will vary dependant on the ambient temperature and the charged
duration.
The DG05 battery comes with a 4-year warranty. The lithium battery needs to be
serviced and replaced at the factory. Do not take the DG05 apart or change the
battery yourself. Warranty is void if the DG05 has been opened or tampered
with.
Switches
On the left and right at the bottom are two black plastic slide switches which you use
to navigate your way through the functions of the computer either on the surface or
underwater.
The switches work in four ways, as follows:-
1. A short push and release of one switch.
2. A push and long hold of one switch (hold the switch in until the screen changes.)
3. A short push of both switches –characterised by thin enclosed brackets < > with
the menu item between them.
4. A long push and hold of both switches (again, hold the switches in until the screen
changes.) –characterised by thick enclosed brackets with the menu item between
them.

Your DG05 is activated by pushing and holding either switch. The first screen to be
displayed will be the Home screen.

DG05 Organic LED display (OLED)
The OLED display gives a clear bright image that is especially readable in medium to
low light conditions, similar to those experienced in many diving scenarios. However,
it should be noted that OLED displays do not perform as well in bright sunlight as
more conventional LCD displays.
The OLED display inherently takes more power than LCD displays. With this in
mind, power can be saved by reducing the number of pixels showing bright colours.
This then leads to a new colour scheme for all screens, and in particular has led to a
revised dive screen that shows the OLED display to its best advantage.
The colour scheme style and new dive screen options can be accessed from the
existing Display Modes screen. When accessing Display Modes, the user is first
taken to the OLED display modes screen.

Gmode can be set to HP (if fitted), TTS or PO2. PO2 is only available if a DG05
rebreather interface (ORI) is fitted.

There are 3 OLED display modes to choose from:
1. OLED mode
2. Dive Screen
3. Dive Toggle
Display Modes Screen
By ticking the OLED mode, the Dive screen mode is automatically turned on. The
OLED Mode basically reverses the white and black of the display, so the background
becomes black, and text and numbers become white.
The OLED Dive option chooses to use the new dive screen with a black background
and new look. There is less information in this screen than the classic version, but
it is more simply and clearly laid out. With this reduction in information in mind, the
Dive Toggle option allows the user to revert to the classic screen for 10 seconds to see
all dive information by doing a short left button press.
Finally, to go to the normal (classic) display modes where further data selections can
be made for the classic dive screen, the user can select the Display modes option at
the bottom of the list. This is the normally highlighted option when going to the
Display modes screen.
Note. These selections cannot be made for the OLED display
Home Screen
Note. The battery indicator on the NHeO 3 will show a voltage, whereas the DG05x
will have a % remaining display.
Note. The screens show (unless identified otherwise) are with the DG05x in non-
OLED Screen mode (see page 11).

Understanding our PIN Upgrade System
DG05 Dive computer comes configured with the external oxygen sensor port turned
on and can monitor up to 3 oxygen sensors.
No external link hardware (cable etc.) is supplied with this computer and can be
purchased separately.
If you purchased your DG05 and wish to upgrade with a new PIN, please contact us
or your dealer to purchase the PIN. Pin information can be found on white strips
attached to the plastic CD envelope that came with the computer. Please keep these
PINs, and any other PINs you subsequently purchase, in a safe place.
To activate the purchased level and features, enter the 16 digit PIN(s) following the
procedure outlined below. To purchase further level upgrades or activate additional
features, contact your DG05 Computer dealer. So that the dealer can give you the
correct PIN(s), when you make the purchase you will need to provide the unique 16
digit serial number of your DG05. This Serial Number is on line 4 of the PIN screen
which can be found in the SETUP menu.
The SETUP menu is accessible via the mini screen feature in the Home screen.
How to enter a PIN
PINs are keyed in using the switches and are logged in on the bottom line of the PIN
NUM screen. A short push on a switch will move the number highlighted by 1; a long
hold will move it by 8. When keying in each digit or letter move forwards using the
right hand + switch. Do not move backwards using the left hand - switch except to
correct, as this may cause previously entered numbers to change. After you have
keyed in the last digit of your PIN there will be a pause before the cursor moves to the
top of the screen you can use the left and right switches to key in your name and
phone number, or any other data you wish, in order to identify the DG05 computer as
yours, (see below).
After a PIN has been successfully installed the bottom line of the screen will
revert to 16 zeros.
