If you have followed the procedure explained into the user’s manual but you don’t succeed after 2 or 3 attempts:

  1. in some (very rare) cases the Instrument is not compatible with the SD card: try with another Card.

  2. Be sure that the protection lever of the SD card is in “off” position.

  3. Be sure that the SD Card is virgin or formatted as virgin before the first use with Compass;

  4. Contact sales@compass-italy.com We will send you the folder to copy inside your virgin SD card to bypass the formatting procedure.
