Note that you can save the current program (the one you are actively in, seen in line 3 of SI
mode) by ensuring that Alpha is clear.
Also note that for filenames, a key difference is that in a CX, the program name can use any 41
characters to make up the filename, whereas when exporting to USB storage, you must use only
'normal' characters for the filename. So you can’t specify 41-unique characters in the filename
such as '%', '↑', 'Σ', etc.
• Select file from list (for overwrite) or <New File> if you want to enter new filename.
Confirm with [ ENTER ]
• [On <New File>] Enter new filename. [ SHIFT ] toggles input mode between lower/upper case
and numbers.
Confirm with [ R/S ] or [ Alpha ].
The program is saved from calculator memory to FAT disk.
6.2.5. Activate USB Disk
Used to copy files from/to a host computer - e.g. backup/restore the calculator state files from
/STATE/ directory or read/write programs in RAW format into the /PROG/ directory.
• Connect the calculator to a computer using a USB cable
• The DM41X’s flash disk should be visible on the computer
• Read/write files
• 'Eject device' on the host machine.
• Calculator should end USB disk mode automatically if correctly ejected by OS.
You can also end USB disk mode by pressing [ ← ] or [ ON ] key on the calculator followed by
[ ENTER ] key for confirmation, but be sure all data are flushed to disk first.
The last two points 'Eject device' and eventually 'Press [ ← ] or [ ON ] key on
calculator' if USB disk mode doesn’t end automatically are important to avoid
unsaved data and possible FAT disk corruption!
For Windows users
In Windows you can eject the disk in two different ways:
1. (Prefered) Right-Click on the drive in any Explorer view and select "Eject" and the DM41X
should leave USB Disk mode automatically.
2. Click the "Safely remove hardware and eject media" icon in the tray, then select DM41X
from the list of devices to eject. After you see the "Safe to remove hardware message" press
[ ← ] or [ ON ] key followed by [ ENTER ] key for confirmation to exit USB Disk mode.
6.2.6. Show Disk Info
Displays disk status and disk block info.
