File menu
1. Load Program >
Used for loading the *.raw programs stored in the /PROGRAMS/ directory of the flash storage.
It should display all *.raw files from /PROGRAMS/ directory in alphabetical order.
To load program
• Select the program to load using the [ ▲ ] and [ ▼ ] keys
• [ ENTER ] to load the selected program
Loading info flashes for a second until the program is loaded into calculator memory.
Then the program list is displayed again. You can load next program or leave the menu by [ EXIT ]
key.
2. Save Program >
Used for saving one or more program(s) from the calculator memory to a *.raw file in the
/PROGRAMS/ directory of the flash storage.
• Select the program or programs to save, confirm with [ ENTER ]
• Choose existing filename as target or type new target filename, confirm with [ ENTER ]
3. 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 /PROGRAMS/ directory.
• Connect the calculator to a computer using a USB cable
• The DM42’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 end USB
disk mode by pressing [ EXIT ] key on the calculator but be sure all data are flushed to disk first.
The last two points 'Eject device' and 'Press [ EXIT ] key on calculator' (if it doesn’t
end automatically) are important to avoid unsaved data and possible FAT disk
corruption!
Note that calculator programs must be stored in the /PROGRAMS/ directory of the
flash storage to be accessible from the calculator menu.
