TX Setup
The Transmitter setup (TX
Setup) menu is used to set up
transmitters� Currently active

to TX Setup in the top level AI
menu�
Up to 4 transmitters can
be configured in this menu�

not currently in use to save
battery power�

Navigate over to and select a
transmitter’s serial number in
the transmitter setup menu
to enter the tank set up menu
for that transmitter�
Serial Number Setup
Every transmitter has a
unique 6-digit serial number
.
This number is etched onto
the side of the transmitter�
Enter the serial number to
pair the transmitter to T1�
This number only needs to be
entered once� Like all settings,
it is stored in permanent
memory� Transmitter settings
are saved across all dive
modes�
Set AI Mode to OFF when AI not in use
Leaving AI enabled when not in use will negatively
impact battery life when the computer is turned on�
When a paired transmitter is not communicating, the
Petrel 3 goes into a higher power scan state� This
increases power consumption to about 25% higher
than with AI off� Once communications are established,
power drops to about 10% higher than with AI off�
Note, AI is never active when the computer is off� There
is no need to turn AI off when the computer is turned
off�
