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.
Operational Modes
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.
