m WARNING!
This is NOT THE MANUAL FOR THE SEAC COMPUTER. This
is the manual for the Transmitter (considered an accessory
of the computer). You must read the warnings provided
in the manual for your SEAC computer before diving. The
SEAC computer manual is available at www.seacsub.com.
WARNINGS (Transmitter)
m WARNING!
DO NOT EXPOSE THE TRANSMITTER TO PRESSURES
GREATER THAN 300 BAR (4351 Psi)
Maximum detectable pressure: 250 BAR (3625 Psi)
Maximum sustainable pressure: 300 BAR (4351 Psi)
The computer and Transmitter are NOT intended for
PROFESSIONAL use.
The computer and Transmitter are intended strictly for use in
sports (recreational or technical).
We advise against using them in professional or commercial
dives, except as an additional tool to support the diver.
• Check the battery status before every dive, although if the
Transmitter turns off during the dive it does not expose
the operator to any risk. (WARNING: Remember that a
pressure gauge is always mandatory on every tank you
use!). We do not recommend diving with the Transmitter
when it has less than 30% charge (red light).
• Before diving, always check that the Transmitter is intact and
shows no signs of cracks or breakage, that the seals on the
screws are intact, and that it has not been tampered with in
any way. If this check fails, do NOT use the Transmitter.
• Do not expose the Transmitter to blows or drops. Never lift
the tank by grasping the Transmitter, for any reason.
m WARNING!
DO NOT USE the Transmitter unless it is in perfect
condition! Using a Transmitter that is unsuitable for use for
any reason - falls, tampering, etc. - puts the user at risk. It
is the user's responsibility to ensure that the Transmitter
is in perfect condition before connecting it to the first
stage or using it in any way. Anyone unfamiliar with these
risks or who does not knowingly accept them must not
use the Seac Transmitter. If you have any questions about
connecting the Seac Transmitter to the first stage or about
the preventive safety checks that must be performed, ask
your instructor.

Care and maintenance
• Keep your Transmitter clean and dry. Do not expose it to
chemical agents, including alcohol.
Use only fresh water to clean your Transmitter,
removing all saline deposits.
m WARNING!
Only wash the Transmitter when it is connected to the
first stage. Do NOT wash the Transmitter if the hole that
connects with the first stage is not properly protected from
the water.
When disassembled from the first stage, affix the
protective cap on the Transmitter threads. To dry the
Transmitter, leave it naturally in the shade. Do not use jets
of cold or hot air.
• Do not expose the Transmitter directly to the sun or sources
of heat higher than 50°C. Store it in a cool (5°C-25°C), dry
place, making sure to put the protective cap on the threads.
• Do not attempt to open, modify, or repair the Transmitter
yourself. Always contact SEAC.
• The warranty will be forfeited if the computer or the
Transmitter are opened by an unauthorized service center.
• Do not place the computer or the Transmitter in a hyperbaric
chamber.
• The GURU computer and the Transmitter are built to
withstand use in sea water, but after the dive they must be
rinsed thoroughly in fresh water and not exposed directly to
sunlight or sources of heat to dry them.
• Check that there are no traces of humidity on the inside of
the device.
m WARNING!
Do not attempt to open the device for any reason.
If you have problems, contact an authorized SEAC center,
or contact SEAC directly. Breaking the seals on the device
immediately and irreversibly voids all warranties on the
product.

Recharging the battery
The SEAC Transmitter has a Li-Ion rechargeable battery with
no memory effect. The battery time data provided can vary +/-
15% depending on the ambient temperature.
m WARNING!
Always fully charge the battery before using the computer
the first time.
You can recharge the Transmitter by connecting it to a USB
wall charger (not included) with the USB cable provided with
the GURU. (The USB cable is not included in the Transmitter
package.)
122
We recommend using a USB wall plug (like those for
smartphones/tablets) for charging the Transmitter.
If you decided to use a USB port on a computer, make sure
that the computer does not suspend power when it switches
to stand-by mode. Charging the Transmitter from a computer
is not recommended because the device might not charge fully.
The Transmitter has approximately 100 hours of diving battery
time (this can vary +/-15% depending on temperature) or 2
years in standby (if the battery was fully charged before it was
stored).
Even if the SEAC Transmitter's next-generation battery has
no memory effect, we still recommend charging the battery
completely. Average charging time is 3-5 hours depending on
the residual charge level.
When charging, the SEAC transmitter activates the BLUE LED.
The blue light switches off when charging is complete. Once
the battery has charged, even if the device is left connected to
electrical power, the Transmitter automatically interrupts the
ow of power. If you leave the transmitter charging for longer
than necessary, and leave it long enough that the Transmitter
battery percentage drops below 95%, charging (and the blue
light) will reactivate automatically to charge the battery back
to 100%.
Nevertheless, we do not recommend leaving the Transmitter
on the charger for more than 8 consecutive hours.
m WARNING!
Don't leave the Transmitter with a completely dead battery
for long periods (e.g. 1-2 months); this can damage the
battery. The Transmitter memory records an alarm if it is
left dead for long periods. This eventuality is not covered
by the warranty. If you need to store the Transmitter for
an extended period, first charge the battery fully and
remember to recharge it from time to time.

PREPARING THE TRANSMITTER FOR THE DIVE
Mounting the Transmitter on the rst stage
The Transmitter must be mounted on a High Pressure (HP) port on the regulator rst stage.
High pressure ports are usually marked "HP". Check the manual for your regulator to identify the correct port.
Mount the Transmitter using the same method, care, and caution you would employ when mounting a high pressure hose
connected to the pressure gauge. Assemble the Transmitter so that it does not interfere with the regulator hoses.
Always check that the sealing O-ring in the lower (threaded) part of the Transmitter is present, intact, clean, and properly
lubricated. Immediately replace the O-ring whenever it is damaged (HP O-ring: 8.73 x 1.78 NBR 70).
m WARNING!
If you do not know how to mount a device on a high pressure (HP) port, contact your instructor!
If the Transmitter is damaged, do NOT mount it on the regulator.
This image is only an example. The correct
connection position on your rst stage may
differ.

Turning on the Transmitter and checking battery status
The Transmitter will turn on automatically as soon as it detects tank pressure.
To start the Transmitter, connect it to a tank and open the tank valve. We always recommend that you open the tank gradually. If
you notice any gas leaking from any device mounted to the tank, close the tank.
m WARNING!
If you do not know how to open a tank safely, contact your instructor!
When starting up, the Transmitter performs an LED check, switching the LEDs on in sequence (Blue, Red, Yellow, Green).
Afterward, it shows the battery status by switching on one of the three LEDs for 3 seconds, depending on the battery time left (see
the image below). Finally, it conrms conclusion of the start-up phase with a blue ash.
Once the start-up phase is complete, the Transmitter begins to display the tank pressure using the Color Code system.

Press the B button to begin searching for the Transmitter (SRC). When
pairing is complete, the Transmitter's TX ID will be displayed on the screen.
(Each Transmitter has 31 TX ID communications channels. The TX ID is
assigned to the Transmitter randomly. You can change the Transmitter TX ID
if there is interference with another Transmitter; see the dedicated section
in this manual.)
To check that the GURU has paired correctly with the Transmitter, activate
dive mode. Within 30 seconds, the tank pressure will be displayed in the
lower right part of the screen (BAR). (The RBT value will only be displayed
during the dive; see the dedicated section in this manual.)
Once paired, the GURU and Transmitter will connect automatically as soon
as the GURU activates OC (Open Circuit) dive mode.
m WARNING!
Using the Transmitter reduces the GURU's battery time to
approximately 20 hours of dive time. Set the TX ID to "OFF" if you are
not using the Transmitter.
