WARNING
The operation of an unmanned helicopter
involves considerable mental fatigue. The
operator should not fly the helicopter contin-
uously for more than 1 hour, but should take
a rest every hour. Prolonged continuous
flight operation could cause the operator to
lose concentration and could lead to an acci-
dent.
WARNING
Do not fly the helicopter after drinking alco-
hol or taking cold medicine, or if you are in
poor physical condition. Flying the helicopter
in poor physical condition could cause loss
of concentration, and could lead to an acci-
dent.
