Switch on the transmitter. Check again TX battery status.
Switch on the receiver (main switch). Check no interference from any other RC transmitter
If the submarine doesn’t switch on, check the fuse and replace if necessary.
Check that the front hood is perfectly installed. If it isn’t, any hit during the launch will cause it to fall down
into the water. It will sink, being heavier that the water. Therefore, pay much attention.
If the camera is not used, check that the cap of the cable connector is tightened. If the camera is used,
see “Camera operation” paragraph.
Start the pump and empty the bag (left stick to left), until the bag is totally emptied. This will be shown by
the changed noise and the absence of air coming out from the water intake.
The main power switch is located at the bottom of the front
flange. From the bottom view, the left switch is to control the
main battery power for all the electric devices. The right switch
is unused.
For fresh water use only.
Check if there is no water is inside the hull. If water is found inside the hull, the submarine shouldn’t be
used until you discover the cause of the problem and solve it.
Close the front cap and tighten the nuts (sequence: opposite nuts). After locking, the front O-Ring should
appear uniformly flattened against the cap.
Switch on the transmitter and check TX battery status.
Switch on the submarine and check the following functions:
Check throttle: move left stick up/down and verify that full forward and reverse speed is reached. In
centre position (idle) the propeller should not move. Correct TX trim if necessary
Check pump: move left stick right and left and verify that the pump starts running and inflates or empties
the ballast. You may hear the noise of the motor and also feel the pump action by placing a finger at the
water intake.
Check dive planes (right stick up/down). Verify that stick neutral position corresponds to horizontal dive
planes. Trim if necessary.
Check rudder (right stick left right). Verify that stick neutral position corresponds to straight rudder. Trim if
necessary.
Switch off RX and TX respectively.
NOTE: Pump action is on-off and it’s normal that it is not proportional. However, be sure that the
centre idle position of the stick is equally far from left and right working position.
Trim if necessary.
NOTE: If the fuse is burnt again, then should be a short circuit inside. Don’t use the model.
Open it and search for any electrical problem)
