R7208SB
Thank you for purchasing a Futaba
R7208SB
FASSTest-2.4GHz
compatible receiver.
The
R7208SB
receiver features bi-directional
communication with a
FASSTest
Futaba transmitter
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 (1-8ch) and
S.BUS
output ports. The
R7208SB
can also be switched to the
Dual Rx
Link
System. This system can ensure safety by
mounting two receivers on one aircraft.

Antenna installation for carbon fuselage
You must leave 30mm at the tip of the antenna fully exposed. The
exposed antenna should be secured so that it cannot move around or
back inside of your aircraft.
Be careful of connector insertion
Don't connect an S.BUS servo / gyro to S.BUS2 connector.
Link precaution
Do not perform the linking procedure while the motor's main power is
connected or the engine is operating as it may result in serious injury.
When the linking is complete, please cycle the receiver power and
ensure the receiver is properly linked to the transmitter.
Please power up your system in this order: Transmitter first, followed
by the receiver.
If the R7208SB receiver was previously linked to another transmitter,
make sure that transmitter is not operating while linking the receiver to
the new transmitter.
Connector precaution
Don't connect a connector, as shown in a
before figure.
■ It will short-circuit, if it connected in
this way. A short circuit across the battery
terminals may cause abnormal heating,
fire and burns
*Be sure that when using ESCs regulated
output the capacity of the ESC must meet
your usage condition.
*Never use dry batteries for the power sup-
ply of the R7208SB as they may cause
difficulties.
Usage precaution
• Analog servos cannot be used with the R7208SB in the FASSTest
12CH mode.
• Don't connect to Extra Voltage before turning on a receiver.
WARNING
Changes or modification not approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
The R7208SB receiver should be protected from vibration by foam
rubber, Velcro, or similar mounting methods. Protect from moisture.
Keep away from conductive materials to avoid short circuits.
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.
Do not touch the antenna to metal, carbon, or other conductive material.
Be sure that the two antennas are placed at 90 degrees to each other.
■
The R7208SB has two antennas. In order to maximize signal reception
and promote safe modeling Futaba has adopted a diversity antenna system.
This allows the receiver to obtain RF signals on both antennas and fly
problem-free.
