Cautions
L
When use decoder with V8 series CPPM receiver. DO NOTuse more than6channels of
CPPM signal. Otherwisedamage may occur.
L
The factory default firmware ofD series (Two-Way) CPPM receiveris21ms for CPPM. If want to
use more than 6 channels, please download and flash with 27ms firmwarefrom
www.FrSky-
RC.com
. The V8 seriesreceiver CANNOT be upgrade with this firmware.
L
Before channel setting, BE SURE there is NO servo connected. There is the danger of
erroneous operation or damage.
L
The decoder’s output PWM frequency is automatically match with the input CPPM/SBUS
signal frequency, make sure the proper servo is connected. Do NOT use conventional servo
with SBUS High Speed mode and/or CPPM mode when frame length is shorter than
14ms.There is the danger of erroneous operation or damage.
L
With Digital servo, CPPM frame length MUST NOT larger than 30ms; in case of conventional
servo, CPPM frame length MUST NOT larger than 22ms. Otherwise erroneous operation or
damage may occur.
L
Before take-off, BE SURE there is no redundantservo connects to decoder. There is the danger
of erroneous operation or damage.
L
DO NOT switch receiver High Speed/Normal Speed mode when decoder is connected.
L
Do not fly until inspection is complete.
