Using Commercial SD Cards
Removing SD Cards
1. Press [POWER] to turn off the JS-8.
2. Remove the SD card connector cover.
3. Push SD card inward, and then release your finger.
4. Remove the SD card.
Remove an SD card only while the JS-8's power is switched off.
Removing an SD card with the JS-8 turned on may result in
corruption of data recorded on the SD card or damage to the
card itself.
Initializing SD Cards
1. Press [MENU].
2. Select SYSTEM, and then press [ENTER].
3. Select SD CARD, and then press [ENTER].
4. Select FORMAT, and then press [ENTER].
5. When the message "Are you sure?" appears, press [ENTER].
Initializing the SD card causes the loss of all data on the card.
Song protection settings are also disregarded. Since there is
no way to recover data after initialization, be sure to back up
any important data before initializing.
If you want to copy data from one SD card to another freshly
initialized SD card, back up the first SD card ("Backing Up SD
Cards" (p. 36)), and then recover the backed-up data to the new
SD card ("Recovering Backed Up Data to SD Cards (RECOVERY)"
(p. 37)).
