Alerts
The device may display various alert messages during use, designed to warn you of abnormal conditions, errors, or situations that require your attention. In most cases, you can dismiss these messages by pressing the navigation button—but we recommend not ignoring them without understanding their cause. These alerts are here to help you maintain safe and reliable operation.
Below is a description of each available alert and what it means:
SD Card Read Error
This alert appears when the device fails to access the SD card while the firmware is initializing its core functions. This alert blocks device usage and cannot be dismissed.

What to do:
If the error persists, repeat the process with another SD card. If this still doesn't fix it, please contact me through the contact section.
Low Battery Warning
This alert is shown when the battery reaches a very low, but not yet critical, level. It’s not an emergency—you should be able to complete your current flight without issue. You may temporarily dismiss the alert with the navigation button, but it will reappear after a few minutes if the battery level doesn’t improve. When the charge reaches a critical level, a permanent alert will appear and disable the device until the battery is recharged or replaced.

The remaining charge level displayed is approximate and, while optimized for maximum reliability, is not 100% accurate. Under no circumstances should you wait for the low-battery warning to recharge the device: in critical situations that alert may arrive too late. It is the user’s responsibility to monitor battery status and recharge the device before it reaches low-charge levels, thereby avoiding unexpected interruptions.
Failsafe Not Set
This alert means that a failsafe has not been configured for the currently selected model. It serves as a reminder that, in case of lost communication between the handle and the receiver, the receiver will continue to act on the last known command—which could be dangerous in certain scenarios.

You can dismiss this alert by pressing the navigation button, but don’t ignore its importance if your model requires a safe default behavior during signal loss.
It is strongly recommended to configure a failsafe for each model, clearly defining what values should be applied in case of signal loss.
