Transmitter Inspection - Yamaha RMAX Type II G Unit Operation Manual

Transmitter Inspection

Inspect the flight transmitter battery level, opera-
tion, and antenna conditions.
If the transmitter has a malfunction or the
battery level is low, the transmitter will be
unable to send radio signals during a flight.
1 Battery Level Inspection
With the main switch on the helicopter turned
OFF, turn the power to the transmitter ON to per-
form the following inspections:
G Check that the output light is ON.
G Listen to the buzzer for the number of beeps
that indicates the battery level.
Beep beep beep beep (4 times)
Beep beep beep
Beep beep
Beep
G Check that the battery monitor light is not illu-
minated.
This light operates in unison with the number
of beeps of the buzzer. It flashes when the
battery level is low. Afterwards, it will illumi-
nate to warn the operator. This condition indi-
cates that the battery level is almost empty,
and it should be replaced with a fully charged
battery.
2 Transmitter Operation Inspection
When the power of the transmitter is turned ON,
apart from the buzzer sounding to indicate the
battery level, if the buzzer beeps in a 3-3-7 pat-
tern or the output light does not illuminate, the
transmitter may be malfunctioning. If this occurs,
cancel the flight and request a repair by your
dealer.
3 Antenna Inspection
Inspect the antenna to make sure it is not loose
in the area where it is mounted to the transmitter.
Extend the antenna and inspect it for looseness
or rust.
If the antenna is loose in the area where it is
mounted, tighten the antenna.
If the antenna is loose or rusted, replace the
antenna.
