Thank you for purchasing a Futaba R6308SBT FASST-2.4GHz compatible receiver. The R6308SBT receiver features bi-directional communication
with a telemetry receiver unit (option) using the S.Bus2 port. Using the S.Bus2 port an impressive array of telemetry sensors may be utilized. It also
includes both standard PWM output ports and S.Bus output ports. This receiver distinguishes automatically FASST-2.4-GHz system 7ch or Multi-
ch/10ch / 8ch mode at the time of link operation with a transmitter. And high speed mode can be chosen.

Usage precaution
󾾝
WARNING
󾾛
Changes or modification not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
󾾙
The R6308SBT receiver should be protected from vibra-
tion by foam rubber, Velcro or similar mounting meth-
ods. Protect from moisture.
󾾛
Keep away from conductive materials to avoid short cir-
cuits.
󾾛
Don't connect to Extra Voltage before turning on a receiv-
er.
Antenna installation precaution
󾾛
Do not cut or bundle the receiver antenna wire.
󾾛
Do not bend the coaxial cable. It causes damage.
󾾛
The antennas must be mounted in such a way to assure
they are strain relieved.
󾾙
Keep the antenna as far away from the motor, ESC and
other noise sources as you possibly can.
󾾙
Be sure that the two antennas are placed at 90 degrees to
each other.

WARNING
󾾙
You must leave 30mm at the tip of the antenna fully ex-
posed. The exposed antenna should be secured so that it
cannot move around or back inside of your aircraft.
