Important Warnings
General Warnings about the CC Transmitter
It is necessary to read this manual carefully before using the computer RATIO®. A wrong use of this computer or its accessories will
nullify the warranty and could cause permanent damages to the device and/or its accessories.
• The diving computer DOES NOT replace an adequate diving training and should be used only by those divers who have been
opportunely trained.
• The Ratio® CC Transmitter DOES NOT replace the PRESSURE GAUGE, so it is compulsory having always a working pressure gauge
for each tank. Even if the CC Transmitter is working properly it is always suggested to check from time to time the pressure gauge.
• The RATIO® computer and the CC Transmitter are auxiliary instruments to the dive, so it is compulsory having always an
appropriate diving chart and a pressure gauge for each tank in order to carry out the decompression phase in case the devices are
malfunctioning.
• Diving has some intrinsic risks which cannot never be completely eliminated.
No computer or diving chart can guarantee that the risk of Decompression Disease (DD) or Oxygen toxicity to the central nervous
system don’t exist, even if the diver follows meticulously and accurately the indications given by the computer or the diving chart.
• The Wireless communication between the dive computer and the Transmitter can stop working, both inside and outside the
water.
• Use the Transmitter far away from any electromagnetic source
• Is possible that the Transmitter can not work properly if electromagnetic interferences are present in the same signal range used
by the Transmitter.
IMPORTANT WARINIG: THIS IS NOT THE MANUAL OF THE DIVE COMPUTER, this is the manual of the Ratio® CC Transmitter (an
accessory of the dive computer). It is mandatory to read the“Warnings” of the manual of the Ratio® dive computer before to dive! The

How to recharge the battery
The Ratio® CC Transmitter has a rechargeable Li-Ion battery without memory effect, the given autonomy data may change
of +/-15% depending on the environment temperature.
ATTENTION: Charge the CC Transmitter completely before using it for the first time.
Recharge the CC Transmitter using a USB wall charger (not inclued) and the“Blue-dot” USB cable of your iDive or iX3M (a
spare USB cable is not included with the CC Transmitter).The USB cable that can be used to recharge the CC Transmitter
have a blue dot on the connector. Do not use “red-dot” USB cable to recharge the CC Trasnmitter, it can damage the
connector of the CC Transmitter. During the recharge the CC Transmitter lights up in blue. The recharge is compleated
when the CC Transmitter turns off.
We recommend to use an USB wall charger (as the one of your mobile phone/tablet) to recharge the CC Transmitter.
In case of use of a PC/Mac USB charger (not recommended), make sure that the PC/Mac doesn’t interrupt the electricity supply when
in stand-by. Recharge the CC Transmitter with a PC/Mac is however not recommended because there is the risk to carry out only a
partial recharge cycle.
The CC Transmitter has 100 diving hr of autonomy with a single charge (this data may change of +/-15% depending on the
environment temperature) or 2 years of stock (if the CC Transmitter was fully charged before the stock)
Even if the CC Transmitter new generation Li-Ion battery hasn’t the memory effect, it is however recommended to recharge it
completely. The average recharge time is 3-5 hours, depending on the battery residual charge level.

Turn on the CC Transmitter and check the battery
CC Transmitter automatically powers up as soon as the tank pressure is detected.
In order to turn on the transmitter, it is necessary to connect it to a tank and then open the tank valve. It is always advisable
to open the tank gradually, and in case gas loss from any of the tools applied to the tank is perceived, close the tank.
WARNING: If you do not know how to safely open a tank, refer to your instructor!
During the boot phase, the transmitter carries out a checking of the leds by powering them up in string (Blue -> Red
-> Yellow ->Green), and after that it indicates the battery level by powering up one of the three leds for three seconds,
according to the battery status (see below chart). Finally, it confirms the end of the boot phase with a blue flash.
Once the boot phase is concluded, the CC Transmitter starts to show the tank pressure throught the Colour Code system.

The CC Transmitter during the dive
BAR / Psi:
The BAR value (Psi if the imperial unit system is set) is displayed in the bottom-right part of the screen of your iDive or iX3M.
The BAr/Psi value shows how many Bar/Psi of gas are left in your tank.
The BAR/Psi value is shown 30 seconds after the connection between the iDive/iX3M and the CC Transmitter. The BAR/Psi value is
updated every 5 seconds during the dive.
In case the connection between the CC Transmitter and the iDive/iX3M would be instable or jammed for more than 1 minute the
BAR/Psi value will be hidden (“---”). The BAR/Psi value will be ripristinated as soon as the comunication is stable for more than 1
minute.

RBT and TANK RESERVE:
The RBT (Remaining Bottom Time) is shown in the bottom-center part of the screen of your iDive/iX3M
The RBT is calculated according to your current breath rate. It may take up to 2-5 minutes in order to let the iDive/iX3M collects
enought data to calculate your breath rate. The RBT is hidden (“---”) if not enought data have been collected from the iDive/iX3M.
The RBT value is personal and can be different from person to person (even at same depth and same tank pressure)
RBT in no-deco dives
If no mandatory deco stops are required for your dive (safety stop and deep stop are not considered mandatory deco
stops) the RBT value is the time (in minutes) that you can stay at the current depth with your current breath rate before
your tank pressure reaches the TANK RES (tank reserve) set in the TRANSMITTER menu.
E.g. (If TANK RES. = 30 in TRANSMITTER menu)
If no mandatory deco stop are required, your RBT will be “0”when there will be 30 BAR of pressure left in your tank.
You can set the TANK RES value (from 10 Bar to 50 Bar) from the TRANSMITTER menu in your iDive/iX3M
WARNING: The RBT is a pure statistic value! The iDive/iX3M can not predict behaviours that can alterate your breath
rate like anxiety, stress or similar.
It can be used just as a mere statistic information. The RBT can never replace a correct scheduling of the dive and
the knowledge of your phisical or mental status.
NEVER use the RBT to extend your dive over the scheduled time.
If you do not know how to schedule a dive, ask your diving instructor!

19
RBT in Deco-stops dives
If your dive requires deco stops (safety stop and deep stop are not considered mandatory deco stops) the RBT is the time
(in minutes) that you can stay at your current depth with your current breath rate, before, considered the time that you will
need to perform the required deco-stops your tank pressure reaches the TANK RES (tank reserve).
E.g. (If TANK RES. = 30 in TRANSMITTER menu and the dive requires mandatory deco stops)
The RBT will be “0”when in your tank there will be enough Bar/psi to let you ascent (with standard speed) and perform the
mandatory deco-stop (deep stops are not considered mandatory deco stops) in order to let you have 30 Bar left in your tank after
the end of your last deco stop.
You can set the TANK RES value (from 10 Bar to 50 Bar) from the TRANSMITTER menu in your iDive/iX3M
WARNING: The RBT is a pure statistic value! The iDive/iX3M can not predict behaviors that can alter your breath rate
like anxiety, stress or similar.
It can be used just as a mere statistic information. The RBT can never replace a correct scheduling of the dive and
the knowledge of your physical or mental status.
NEVER use the RBT to extend your dive over the scheduled time.
If you do not know how to schedule a dive, ask your diving instructor!
