FAIL-SAFE PROTECTION
1. Press the [BIND] button once within 10 seconds of the receiver being
powered ON, and the receiver will save all the current channel values
of the remote control as the fail-safe value.
2. 10 seconds after the receiver is powered ON, the [BIND] button
function will be disabled to prevent accidental changes to to the
fail-safe settings while preparing the model
for flight.
*Note: D8 and D16 compatible receivers MUST be frequency
fine tuned prior to flight.
Once the radio is bound to the receiver:
Go to the RF Freq. fine tune option in Model Setup.
1. Lower the value until the radio loses the connection with the receiver.
? Record the value (TUNE_MIN).
2. Raise the value so that the connection is restored, then continue to
raise it until
the radio loses the connection with the receiver again.
? Record the value (TUNE_MAX).
3. Calculate the median between the two values
?(TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
4. Set RF Freq. fine tune to the median value
?Example: Connection is lost at -73 and +35; the median is -19:
*Once the Fine Tuning value is known, it can be used for all models
that use the same protoco
l.
