Custom: The receiver maintains the deflection value on all channels as you pre-select 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 deflections and confirm the selection. Then set the deflections 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 signal loss. This could cause potential damage. If Fail-safe is disabled on the RF side of the module, the receiver will go into default Hold mode. Do not set the Fail-safe mode for the SBUS port to No Signal mode because the signal would be continuously transmitted, set the SBUS port to Hold or Custom mode.
