Custom: The receiver keeps the rate values on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to "Custom". Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.

Note: If fail-safe is not set, the model will always operate with the last functional state of the channels before the signal loss. This could cause potential damage. If fail-safe is disabled on the RF module side, the receiver will go to the default Hold mode. Do not set the Fail-safe mode for the SBUS port to No Signal mode as the signal would be continuously transmitted, set the SBUS port to Hold or Custom mode.
