PrecautionsPrecautions
1. Install two receivers on the aircraft as shown
in the wiring diagram on the next page.
2. Link the two receivers using the dual receiver
feature of the transmitter.
For systems without dual receiver capability,
link each receiver in turn.
WARNING
Failure to follow these safety precautions may
result in severe injury to yourself and others.
In order to prevent any short circuits,
please observe the polarity of all
connections.
Ensure that the unit is connected
properly to the receiver.
■If the connector is disconnected during
flight, it becomes inoperable.
Ensure that the unit is mounted in an
area that will eliminate exposure to
fuel, water and vibration.
■As with any electronic components, prop-
er precautions are urged to prolong the life
and increase the performance of the unit.
Allow a slight amount of slack in the
unit cables and fasten them at a
suitable location to prevent any damage
from vibration during ight.
Be sure to link the two receivers with
the transmitter.
■It will not work unless the two receivers
are linked. After startup, even if the link on
one side is disconnected, the other side will
continue to operate normally.
Used in a set of Futaba S.BUS / S.BUS2
systems.
Do not supply receiver power from
the ESC. When using the receiver
power supply type ESC, remove the red
(+) cord of the 3ch wiring from the ESC
so that the power is not supplied from
the ESC.
■Use a dedicated battery to power the
receiver / servo.
Don't mount FDLS-1 away from
magnetic bodies.
To ensure that the FDLS-1 is
functioning as desired, please test
accordingly.
■Do not fly until inspection is complete.
Before the flight, disconnect the
wiring of the main receiver from
the FDLS-1 that is operating normally,
and check if the sub receiver alone can
control it.
■Check if the FDLS-1 switches.
Do not use the FDLS-1 with
anything other than an R/C model.
