Precautions During Flight - FUTABA 4VF-FM Instruction Manual

PRECAUTIONS DURING FLIGHT

WARNING
Do not fly simultaneously on the
same frequency.
Interference may
cause a crash.
*Use of the same frequency will cause inter-
ference even if the modulation method (AM,
FM, PCM) is different.
Do not fly on rainy or windy days, or
at night.
Water will penetrate into
t h e t r a n s m i t t e r a n d
cause faulty operation,
or loss of control, and
cause a crash.
Extend the antenna to its full
length.
If the antenna is too
short, the effective
r a n g e o f t h e
radiowaves will be-
come shorter.
Check that the transmitter antenna is not loose.
If the transmitter antenna comes off during use, control will
be lost and the model will crash.
PROHIBITED ITEMS
Simultaneous flight on
the same frequency
prohibited
Do not fly
Rain Wind
Night
MANDATORY ITEMS
Always test the digital proportional R/C
set before use.
Any abnormality in the digital proportional
R/C set, or model, may cause a crash.

*Before starting the engine, check
full length
that the direction of operation of each
servo matches the operation of its
control stick. If a servo does not move
in the proper direction, or operation is
abnormal, do not fly the plane.
CHECK ITEMS
Do not fly in the following places:
-Near other R/C flying fields (within
about 3km)
-Near people on the ground, or ob-
jects in the air
-Near homes, schools, hospitals, or
other places where there is a lot of
people
-Near high tension lines, high struc-
tures, or communication facilities
Radiowave interference and obstructions
may cause a crash. A crash caused by
trouble in the R/C set, or the model itself,
may cause death or property damage.
Do not fly when you are tired, sick,
or intoxicated.
Fatigue, illness, or intoxication will cause
a loss of concentration or normal judg-
ment and result in operation errors and a
crash.
