The SD slot is located on the top panel of the W341. To install an SD memory card, you must first remove the

SD slot’s protective cover to access the slot, and then plug the SD memory card directly into the slot.

The SD memory card will be mounted at /var/sd. Detailed installation instructions are shown below:

Step 1:

Use a screwdriver to remove the

screws holding the SD slot’s outer cover, and then remove the

cover.

Step 2:

Insert the SD memory card as shown.

NOTE

To remove the SD

memory card from the slot, using a fingertip, gently press the card further into the machine

and

then remove the pressure, allowing the card to spring outwards. You may now grasp the top of the

card

with two fingers and pull it out.

Before removing the SD memory card, remember to check the /sync directory to ensure that your data has

been written.
