Dive function
The dive (submerge) function adjusts the level of water in the flood tank. When water flows into the tank, the
model becomes heavier, and it submerges. Reducing the quantity of water causes the model to surface
again. Briefly pressing the submerge / surface knob enables the operator to find a position at which the
model “hovers” (remains stationary) in the water. If the model does not submerge even though the tank is
full, then there are small air bubbles inside the open area of the conning tower, or adhering to the hull. You
can eliminate these by pushing the model under the water for a moment and moving it around until the
bubbles rise to the surface.
Maiden run
Charge the battery and check each of the model’s functions in turn. Ensure that all the loose parts are firmly
located - especially the switch flap. You can now launch the sub on its maiden run. Note that you may need
to push the model under the water for a moment to allow air bubbles to escape from the open conning tower
area. Operate the boat very cautiously initially, and give yourself plenty of time to get used to its handling on
and in the water. Don’t let it get too far away from you - you must never lose sight of the boat!
We hope you have many hours of pleasure running your GRAUPNER U-16 model submarine.
