Radio Signal Interference Inspection - Yamaha RMAX Type II G Unit Operation Manual

Pre-Flight Preparation and Inspection

Radio Signal Interference Inspection

Because this product is operated by wireless radio
signals, the presence of radio signals with the same
or neighboring frequency in the vicinity will cause
the signals to cross, which will adversely affect the
control of the flight. Before a flight, use the supplied
radio signal monitor to check the radio frequencies
that are being transmitted in the area. (See the
operation manual of the radio signal monitor for its
operation procedure.)
During monitoring, make sure the power switch for
the flight transmitter is turned OFF.
G The unmanned helicopter for industrial
applications is operated by way of radio
signals. To prevent the helicopter from
going out of control due to unexpected
radio signal interference, pay careful
attention to any radio signal interference
before and during a flight.
G Cancel the flight if you detect the same fre-
quency that you will be using in the vicin-
ity. Otherwise, the radio signal interference
could render the helicopter out of control,
and could lead to serious accidents.
G Check for radio signal interference regu-
larly, including during breaks between
flights.
G Check for radio signal interference each
time you move to another area.
