WARNING
- This product is not a toy, user need model hands-on experience. Please be careful when using, we do not assume responsibility for any property damage or personal injury caused by use this product.
- Remove ESC and motor before run binding procedure or else may result in serious injury.
- Use reasonable failsafe setting, under the premise of ensuring safety, remove motor gear, then power off transmitter to test failsafe working properly or not.

BIND
Power on the receiver then press the
-
mode : Bidirectional communication between transmitter and receiver, receiver will send telemetry packet to transmitter, user can set the alert voltage value on the transmitter. One model file on the transmitter can bind more than one mode receiver **but user need keep ONLY ONE receiver power on at the same time,** because more than one mode receiver working in parallel will results in telemetry packet error. -
mode : One-way communication between transmitter and receiver, user can’t view the telemetry data and signal strength on transmitter.
ATTENTION
- Pay great attention when connect telemetry voltage, ESC, servo or BEC to keep correct polarity, otherwise receiver may break down or on fire.
- The CT series transmitter use LDARC 02 wireless system, each model file of transmitter have unique ID. This feature lets receiver bind to model file instead of transmitter. If receiver does not bind to current running model file will go to failsafe mode, even when use the same transmitter.
- Setting failsafe on the transmitter
, , menu. - Only CH1234 four channels support 50Hz / 100Hz / 200 Hz servo speed setting. Other channels always keep 50Hz PWM output. Please read your servo’s manual to determine servo speed setting, above the maximum support speed maybe damaqe the servo. Setting servo speed on the transmitter
, , menu. - After setting failsafe and servo speed on the transmitter, receiver perform user setting not more than 20 seconds.
- All the channels of CR1800 will keep 50Hz PWM output after power on, receiver perform the failsafe and servo speed setting not more than 20 seconds after receiving signals.
