SD card slot
Data is stored on a removable SD card. For more information on how to work with the SD card, refer to Working with the Memory
Device.
If no SD card is inserted, data storage is not possible.
Unplugging connection cables or removing the SD card during data logging or streaming can cause loss of
data. It is recommended to switch off the instrument before removing the SD card.
While other SD cards can be used, Leica recommends to only use Leica SD cards and is not responsible for
data loss or any other error that can occur while using a non-Leica card.
SD cards can directly be used in the Leica USB Card Reader (767895 MCR7). Other computer card drivers
can require an adaptor.
If formatting the SD card is necessary, we highly recommend to format the SD card on the instrument. Refer
to the How to reset the receiver settings - Step-by-step format the SD card for detailed instructions.
