d) Range test
Before using the model boat for the first time, charge the battery (and any rechargeable batteries for the remote
control) in accordance with the manufacturer’s instructions.
After inserting the battery, follow the steps below to test the range of the remote control. Connect the boat battery to
the speed controller and switch the remote control on. Ask someone to hold the model for you while you walk away
with the remote control.
The remote control should work from a distance of at least 50 m. The maximum range is approximately 100 m.
e) First use
Before using the boat, ensure that the hull shell is attached correctly and locked in place, otherwise it may fall off. In
addition, water may leak into the boat if it capsizes, which could destroy the motor or remote control parts (or cause
the boat to sink). This will void the warranty.
Avoid sudden steering movements, otherwise the model boat may capsize and you may lose control. If you do not
retrieve the boat quickly, water may leak into the boat and cause it to sink.
The boat is designed so that it can return to its normal position if it capsizes (i.e. when the bottom of the
boat faces upwards).
If the model boat capsizes and turns upside down, water will leak into the left-hand side of the boat. This will
force the boat to turn on its side and return to its original position, after which you can continue to drive the
boat. The water that leaked into the left-hand side of the boat will be flushed back out when the boat starts
to move. Practice returning the boat to its original position after it capsizes by placing it in a swimming pool
or near to the edge of the water.
For safety reasons, the speed controller features undervoltage protection that constantly monitors the battery voltage.
If the battery voltage drops below a fixed threshold, the speed controller reduces the power of the motor by approx.
20%. If this occurs, the battery only has enough power for approximately 30 seconds of travel (approx. 100–150 m) to
bring the boat back to the edge of the water. The speed controller will switch off the motor when the battery is empty.
If the motor stops (in order to prevent the battery from overdischarging), you will not be able to control the
boat and retrieve it from the water.
To prevent the battery from overdischarging, bring the boat back to the edge of the water after 8–9 minutes
of use (the battery life may vary depending on the operating temperature, battery type, and how you oper-
ate the boat).
Do not use the model boat in adverse conditions such as strong winds or waves, otherwise you may not be able to
retrieve it from the water.
If you notice any unusual noises or a sudden loss in speed or power, discontinue use immediately and establish the
cause of the problem. In most cases, this is likely to be due to seaweed or other objects that are caught in the propeller
and cause the motor to slow down or stop completely. Discontinue use immediately, otherwise the components may
by damaged due to overheating. This will void the warranty.
Before using the model boat, check that the water cooling system is working properly. Attach a small piece of tube to
the water cooling intake (on the bottom of the hull) and blow air into the tube. The air (or water when the model boat
is moving) must come out of the outlet on the back of the hull.
