4.6 Installing and Removing an SD Memory Card
This section describes a procedure for installing and removing an SD memory card. Note 4.2
(1) Installing an SD memory card
Pay attention to the direction of an SD memory card and install the card according to the following procedure.
1. Insert an SD memory card straight into the SD memory card slot.
The notch part of the SD memory card must be on the lower side.
After installing the SD memory card, check that it is inserted completely. Poor contact may cause
malfunction.
2. The SD CARD LED starts flashing, and turns on when the card is ready to be used.
3. Check that the SD CARD LED remains on.
If the SD CARD LED does not turn on even after an SD memory card is installed, check that SM606 (SD memory card
forced disable instruction) and SM607 (SD memory card forced disable status flag) are off.
Note 4.2
