RE: Question on DM15L upgrading...
The programming instructions on the website don't work for me. Try this.

After choosing the correct COM port,

1. Press and hold the RESET button on the back of the calculator.
2. Click the Program button on the Firmware Update Tool.
3. Release the RESET button.

Firmware update done in 11 seconds.
