Precautions

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 flight. 

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 the 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.
