F / S MENU ( FAIL SAFE )
Three Fail Safe options are available for each channel as described below:
FREE - Fail Safe is Disabled for this channel. Servos can move freely when the signal is lost.
HOLD - When Fail Safe Activates, the servo will be held in the last position it was in when the signal was lost.
% (PERCENTAGE) - When Fail Safe Activates, the servo will travel to the programmed position when the signal is lost.
WARNING: The Fail Safe function will NOT OPERATE if the receiver loses power. For example, if the receiver battery were to
die or come unplugged. It will operate only if the transmitter and receiver signal is interrupted or if the transmitter loses power.
Selecting the Menu and Channel:
1) From within the SETTING menu, press the UP or DOWN keys to highlight the F/S
menu. F/S ST F/S FREE will be highlighted.
If the cursor is flashing over Channel/Options, press the ENTER key to stop the
cursor flashing, then press the UP or DOWN keys to select the F/S menu.
2) Press the BACK key so that the cursor is flashing over Channel/Options.
3) Press the UP or DOWN keys to highlight the desired channel you would like to
change the Fail Safe value for, then press the ENTER key.
Choosing the Fail Safe Settings:
1) Press the ENTER key, then press the UP or DOWN keys to choose the desired Fail
Safe value for that channel. If you choose to program a % value, see step 2 below.
F/S setting range is FREE, HOLD or %. The default setting for all channels is FREE.
2) To program a Fail Safe % value do the following: While the cursor is flashing over
the Fail Safe 0% value, move the transmitter control (e.g., the Throttle Trigger) the
desired amount, then press and HOLD the ENTER key until an audible Tone sounds.
The direction and percentage the servo will travel will be displayed. For example, to
set the Brakes to Engage when the Fail Safe function Activates, push the Throttle
Trigger toward the Brake Side the desired amount, HOLD the Throttle Trigger in that
position, then press and HOLD the ENTER key.
Setting the Receiver Battery Voltage Fail Safe Function:
The Receiver Battery Voltage Fail Safe function is designed to alert you when your receiver battery requires recharging. This
ensures that the receiver battery's voltage doesn't drop so low that your servos aren't provided adequate voltage to operate optimally.
When Activated, the Throttle servo will move to the predetermined position that you programmed in step 5 in the Choosing the
Fail Safe Settings section above to indicate your receiver battery's voltage has dropped below the programmed Voltage value.
IMPORTANT: This function is designed for use with glow- or gas-powered models that use a separate receiver battery pack.
We don't recommend using this function with an electric model that uses a motor battery to power the servos and receiver.
1) Follow the steps in the Selecting the Menu and Channel, and Choosing the Fail Safe
Settings sections above to program a Throttle Fail Safe percentage value.
If FREE or HOLD is chosen for the Throttle channel, you cannot Activate the
Receiver Battery Voltage Fail Safe function. A % value must be chosen for the
Throttle channel to be able to program and use the Receiver Battery Fail Safe function.
2) From within the F/S TH menu, press the DOWN key to highlight B-F/S OFF.
