This applies when:

The Instrument does not start properly or refuses to start (Red LED flashes and
nothing appears on the screen)

The user decide to down grade (load a firmware version with a lower major release
version).

The new software version requires resource files that are not compatible with older
versions. This situation may happen with significant firmware changes and will be
specified by VMI on the download page of the new firmware release.
Step 1: Stop the instrument and connect to a PC using USB cable. Copy the firmware
program file and the associated resource files in to the designed folders. For downgrade,
remove the newest firmware files.
Step 2 : Start the instrument in boot loader mode
2.1 Press the (F2) key.
2.2 While keeping (F2) pressed, press the ON/OFF key to
start the instrument.
The Instrument will now start in BOOTLOADER mode,
showing the boot loader screen (presented on the right).
Step 3: Load from Card in RAM (recommended)
The Instrument will load the newest program file from the SD Card (the SYSTEM folder) in
program memory and enter automatically in Update menu.
Step 4 : Update program file ( (F3)) and resources as necessary
This step is performed in the usual way, once the program is loaded in memory.
Step 5 : Restart the instrument
