Introduction

Congratulations on the purchase of your Aqua Lung EPG®electronic pressure gauge. The

EPG is the world’s first stand-alone electronic pressure gauge that gives a digital read out of

cylinder pressure, temperature, remaining air time, and time of day. It also has a remaining air

time bar graph for quick reference. The EPG uses an electroluminescent (EL) backlight called

Digilite™ and the AutoEL™technology. Unlike other backlights, the Digilite™ lights up the

numbers and characters, not the background. The AutoEL™feature automatically activates the

backlight when any of the warnings are sounded, a great feature when diving at night or in low

light conditions.The AutoEL™feature can be turned on or off.The EPG has audible alarms that

you can set, including a low pressure alarm and a remaining air time alarm.

The EPG is a perfect complement to non air-integrated dive computers, like the ones found in

the Aqua Lung Pivot series. Since the EPG®is the same size as the Aqua Lung analog

pressure gauge, it will fit into the Aqua Lung Pivot®console boot. It will also fit into many other

consoles from other manufacturers.

As with all diving equipment, it is crucial to understand the features and functions of the EPG®.

Before using the EPG®, it is essential to read this manual in its entirety. Contained within this

easy to read manual are illustrations to aid you in the complete understanding of the EPG®.

Section 1 covers the operating instructions and explains all the modes and displays. Section 2

offers advise on care and maintenance, and instructions on changing the battery. Lastly,

Section 3 contains the technical specifications.

IMPORTANT NOTE: The EPG gives true pressure and air time readings. Air time

is the amount of time until the cylinder pressure reaches 0 psi/bar. Before using

the EPG for the first time, set the low pressure alarm and air time alarm to a

comfortable margin. The default settings for these alarms are 500 psi (34.5 bar)

and 10 minutes, respectively. See page 5 for instructions on setting the alarms.

Operation

Activation.

The EPG®is activated by pressing either button. The EPG will not

activate any other way. The gauge can be activated above or

below the water.

OperationalModes

The EPG has three operational modes: Sleep Mode, Standby

Mode, and Active Mode.The EPG enters Standby Mode immedi-

ately after activation, or after breathing is suspended for 5 minutes.

The EPG enters Active Mode when it detects a pressure drop

(breathing starts) of more than 1.6 bar/min (23 psi/min). If the

cylinder presure is greater than 3 bar (45 psi) and the unit has

been in Standby Mode for 30 minutes, it goes into Sleep Mode. If

cylinder pressure is less than 3 bar, (45 psi), the EPG enters sleep

mode after 5 minutes. Each mode is discussed in detail in the

sections below.

Standby Mode

In Standby Mode (figure 1), the EPG will display the Standby Mode

icon (a), cylinder pressure (b), air time meter (c), temperature (d),

and time of day (e).You can toggle air time and time of day by

pressing the right button. Pressing both buttons will activate the

backlight.While the EPG®is in Standby Mode, you may access the

menu system.

Active Mode

The Active Mode (figures 2 &

3) is denoted by the animated

bubbles coming from the

regulator icon (a). In Active

Mode, the EPG displays the

current tank pressure (b), air

time meter (c), temperature

(d), and time of day (e). During

Active Mode, pressing the left

button activates the backlight.

Pressing the right button

toggles the time of day with

remaining air time (f).

Sleep Mode

In Sleep Mode (figure 4), the EPG only displays the time

of day (a). If the EPG is in Sleep Mode, you must

activate it by pressing either button before using it on a

dive.

NOTE: Do not worry if you forget to turn the EPG on

before the dive. The EPG can be activated under water.

Menu System

The EPG®has four menu options (figure 5): Check Battery, Set

Alarms, Set Time, and Set Units.The menu system can only be

accessed while in Standby Mode.You navigate through the menu

system by pressing the left button. The screen for each mode shall

appear, along with the menu cursor denoting which mode it is.

When you reach the mode you want, press the right button to

select (except Check Battery). While in any of the set modes,

pressing the right button increases a value and pressing the left

button decreases a value. Pressing and holding either button

accelerates the change. Pressing both buttons accepts the new

setting and advances to the next setting and exits the mode after

the last setting.

Check Battery

1. Press the left button once to advance the cursor over the

Battery Icon.

2. For this mode, you do not need to press the right button to

select. Pressing the right button will return you to Standby

Mode.

3. The unit displays the battery voltage (figure 6). If the battery

displays a voltage lower than 2.75v, it is highly recommended

that you change the battery immediately. (See page 10 for

battery warning).

4. If there is no button activity for 30 seconds, the gauge will

automatically return to Standby Mode.

Set Alarm

1. Press the left button twice to advance the cursor

over the Alarm Icon.

2. Press the right button to select.

3. The cylinder pressure starts to flash (figure 7).

Press the left or right buttons to change the

setting in 10 psi (0.5 bar) increments. When you

reach the desired setting, press both buttons to

accept.

4. The Air Time starts to flash (figure 8). Press the

left or right buttons to change the setting. Press

both buttons to accept.

5. The EL (electroluminescent backlight), along with

the word ON or OFF, begins to flash (figure 9).

Press the left or right button to toggle between

ON and OFF. Press both buttons to accept and

return to Standby Mode. If set to ON, the

backlight will automatically come on whenever

any alarm is activated.The backlight will stay on

for 10 seconds.

Note: To turn off any of the alarms, set them to 0. If

there is no button activity for 30 seconds, the gauge

will automatically return to Standby Mode.

CareandMaintenance

The EPG®is a robust instrument designed to withstand the rigors of SCUBA diving. However,

you need to protect it from shock, extreme heat, chemical attack, and tampering.

Even though the EPG’s material is tough and durable, it is susceptible to chemical attack and

scratches. Chemical attack can be in the form of spray propellants, gasoline fumes in your

garage or boat, and alcohol. Aqua Lung cannot replace scratched lenses, therefore it is

recommended that you purchase a lens protector. Small scratches naturally disappear

underwater.

CAUTION: Never use aerosol sprays, including silicone sprays, on or near the

EPG®. The propellants may chemically attack the plastic, causing the plastic case

to crack.

Before the dive

The EPG’s plastic housing is made of a shock resistant resin.This housing, combined with the

rubber console boot, protects the EPG from the normal bumps that occur while diving.

However, the EPG cannot withstand the impact of heavy objects, such as weight belts or

SCUBA cylinders.When you set up your dive gear on a boat or the beach, tuck the EPG into

your BC pocket, or between the BC and cummerbund. Never leave the computer exposed

where someone could accidentally step on it or drop something on it.

During the Dive

The most common damage inflicted on gauges while underwater is scratches to the gauge

face. Scratches occur when dangling gauges get dragged over coral or rocks. Most BCs have
