Memory Card Installation
This section presents how to insert the memory card into the models NX3010, NX3020 and NX3030

When the card is correctly installed, a symbol will appear on the CPU graphic display. For card
secure removing the MS key must be pressed then there is a little delay and the card symbol will
disappear from the graphic display. The card is now ready to be taken off. For that, the card must be
