Attention

• For safty, it is recommended that all users pre-set this function before use.

Servos Frequency

This function is used to adjust the servo control frequency. This function can be used for analog servos (95Hz), digital servos (380Hz) and can also be set to custom. Digital servos and custom frequencies range between 50-400Hz.
The servos frequency varies slightly with the connected receivers.

For the Classic Version Receiver

Setup:

1. Click [Servos Frequency].
2. Click the corresponding option. Click to return to the previous level interface.
   If the transmitter RF Setting is set to [AFHDS 3 1 way], modify the servo response speed and then tap . The system prompts "It takes effect after bind or re-bind. Are you sure you want to bind?"
   
3. If you choose [Custom], click "+" or "-" to adjust the frequency.

For the Enhanced Version Receiver

[SR]: One of the specifications in the servo frequency (PWM frequency is 833 Hz).
[SFR]: One of the specifications in the servo frequency (PWM frequency is 1000 Hz).
Note: the conventional servo response speed (PWM frequency) is 50-400 Hz. The overall system delay will be decreased when SR and SFR are selected. Make sure that the adapted servo supports the corresponding frequency. Otherwise, it may cause the servo not to work properly or even damage the servo.

Setup:

1. Click [Steering Digital Servo] or other options to enter the function setting interface.
2. Click the corresponding servo frequency according to the actual state of the adapted receiver. Click to return to the previous level interface. Click the check box on the right of [Synchronized with RF]. The icon will change to . The servo frequency of this function will be synchronized to RF after it is checked.
3. If you choose [Custom], click "+" or "-" to adjust the frequency value.

Both the analog servo (95Hz) and the digital servo (380Hz) are common servo frequencies and as such, are available as presets for quick setup. In order for servos to operate normally they must receive the correct frequency, to find the frequency refer to the servos user manual.

Firmware update

The transmitter's firmware can be updated by connecting to a Windows computer using a USB Type-C cable. Once this function is activated, all transmitter functions will stop working. To prevent the vehicle from losing control, power off the receiver before attempting to use this function.

• 
  Do not disconnect the USB Type-C cable while the firmware is being updated!

This firmware can be updated via the following two ways.

• The firmware of this receiver can be updated through the FlyskyAssistant (The firmware of FlyskyAssistant is available on the Flysky official website).

  1. Download and open the latest official software;
  2. Connect the transmitter to the computer via USB Type-C first;
  3. Touch [Firmware Update]. The system will display the warning: "Entering update mode will disable all other functions.", touch [Yes] to continue;
  4. After completing the above steps, click [Update] in the computer update software window to start the update;
  5. Once the update is complete, the transmitter will exit the update function automatically and reboot. (It is now safe to remove the USB Type-C cable).

Attention

• After a firmware update the receiver may not connect. If this is the case the RF module and receiver need to be updated.

RF Module Update

Setup:
The update RF function can be used to update the firmware of the built-in RF module.
After the firmware of the transmitter is updated, you need to update the RF when the system prompts that the RF fails or the bind of the receiver fails.
Click [Update RF], Click "Yes" after the prompt interface pops up. An update progress bar appears. Wait a few seconds. The update is completed. The transmitter will automatically exit the update interface. If the transmitter cannot enter the update RF status, there is no RF module or the RF module is faulty.

Updating Receiver Firmware

Each transmitter update comes with a receiver firmware update which needs to be uploaded to the receiver to make the most of optimizations and features that are included in the update.
Different receivers may have different ways of entering the firmware update status. Please refer to the instructions of related receivers in the website.

Setup:

• Some receivers such as GMR and INr4 need to be updated with "Flysky Assistant".
• If the transmitter has successfully coded and the connection is established, if the receiver firmware is the latest version, a pop-up prompt will appear [The current version is the new version, no upgrade is required! ]. If the receiver firmware is an old version, a pop-up prompt [Are you sure to update the receiver? ]. Click [Yes] to update the receiver.
• If the receiver and the transmitter are not connected, then enter the receiver selection interface (FGr8B/FGr4B needs to be placed upright when in use), check the receiver to be connected and pop up a prompt [Please connect XX or enable XX enter the mandatory update mode] Click [OK]!

There are two methods to let the receiver into forced update mode:

1. Power on the receiver while pressing the BIND button for more than 10 seconds, until the LED is in a state of three-time flashing and one off, then release the BIND button.
   
2. Power on the receiver first, then press and hold the BIND button for more than 10 seconds, the LED of the receiver will be in a state of three-time flashing and one off, then release the BIND button.

After starting the update, the transmitter will display as below. Once the update as reached 100%, the update is successful.

• The transmitter firmware must be updated before updating the receiver firmware.

Binding

The transmitter and receiver have already been pre bound at the factory, however if you wish to bind again or bind a new receiver follow the steps below:

1. Put the transmitter to enter bind mode;
2. Press and hold the receiver BIND button while powering on the receiver, then release the BIND button after receiver is powered on, or power on the receiver first, then press and hold the BIND button 3 seconds, the LED of the receiver will flash rapidly, indicating that the receiver is in bind mode;
3. The binding process is complete when the LED of the receiver stops flashing and is solid on;
   • If a transmitter that has had its radio frequency (RF Standard) set to "AFHDS3 1 way" (Please refer to your transmitter user manual) enters bind mode, the LED will instead flash slowly. You need to manually put the transmitter to exit the bind mode. If the LED of the receiver stops flashing and is solid on, the binding process is complete;
4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.

These steps are only for the Noble NB4+ transmitter in use with the FGr4B receiver. If you are using other receivers please visit the website for more information.
