See Appendix F for detailed information on the contents of the SD Card.
To install a Micro SD card: Align its 8-pin gold edge connector down, facing the front of the
CL1 unit as shown in Figure 6.3; then carefully push it all the way into the Memory slot.
Ensure that it clicks into place. To remove the Micro SD card: Push down on the top of the
card gently to release the spring. The card pops up for removal. Make sure to format the SD
card before first use whenever a new card is purchased.
