Event message:
SD Card Ejection
Explanation:
The system has detected that the device's SD memory card storage medium is no longer present. This alarm serves only as a status message and has no impact on the core operation of the system. After removing the SD memory card, access to historical data is limited. Newly generated operating data is automatically and temporarily stored in the device's internal memory and transferred to the SD memory card after it is reinserted.
Corrective measures:
Check if the SD memory card was removed manually. If this is the case, reinsert it.
If the SD memory card remains in the slot, remove it completely, clean the contacts with a water-free alcohol wipe, check the slot for foreign objects, and then firmly reinsert the card.
This message will be automatically deleted as soon as the SD memory card is recognized by the system again. You can check the status in the data query interface.
If the message persists after repeated insertion attempts, the SD memory card or the card slot hardware may be damaged. In this case, contact Service.
