SD Cards
The integrated SD card slot is located at the top of the device. In order to 
access it, please open the metal lid first (see ‘How To Open The Metal Lid’ on 
page 5). It supports SD or SDHC cards. SDHC cards are recommended.
Inserting The SD Card
Hold the SD card as shown on the device! The canted edge must point to the 
status LED and the pins must face towards the display. Now, carefully push the 
SD card into the SD card slot until it clicks and snaps into its position. 
Removing The SD Card
Slowly and carefully press the already inserted SD card into the device a 
little further. Then, release the pressure. The implemented mechanism will 
automatically release the SD card, which will then stick out from the slot. Use 
two fingers to pull the card out of the slot.
Kensington Security Slot
In order to prevent unauthorized removal, you may use Kensington lock security 
equipment. Attach the cable around an immovable object, insert the compatible 
connector into the Kensington Security Slot of the PLEXUS and secure the lock 
according to the instructions provided with the lock, for example by turning the 
key or the combination lock.
