FUTABA 3GR-2.4G Instruction Manual page 8

(Turning on the power switches)
Always check the throttle stick on the transmitter to be sure it is at the neutral position.
1. Turn on the transmitter power switch.
2. Turn on the receiver or speed control power switch.
(Turning off the power switches)
Always be sure the engine is not running or the motor is stopped.
1. Turn off the receiver or speed control power switch.
2. Then turn off the transmitter power switch.
If the power switches are turned off in the opposite order the model may unexpectedly run out of control and cause
a very dangerous situation.
(Fail safe function) ---when using HRS mode
Before running (cruising), check the fail safe function.
Check Method:
Before starting the engine, check the fail safe function as follows:
1. Turn on the transmitter and receiver power switches.
2. Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail
safe data to the receiver every minute.)
3. Check if the fail safe function moves the servos to the preset position when reception fails.
The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when
reception fails. However, if set to a dangerous position, it has the opposite effect.
Setting example: Throttle idle or brake position
