Enabling/disabling 3 Tonne Limit in older Gen 3 display software can be done by directly editing a configuration file on the Gen 3 Display SD card
Enabling/Disabling the 3 Tonne Limit in older display software versions requires a PC/Laptop, an SD card reader and the Windows 'Notepad' app.
Steps to edit the relevant parameter:
1. Turn on and boot the computer
2. Insert the SD card from your telehandler into the card reader
3. On the SD card, locate the file: data.cfg
4. On your PC, start the app: notepad.exe
5. Drag and drop data.cfg onto the open notepad page - image below represents some of what you will see.
6. The parameter that requires change is:
3TLimitEnabled=
A 1 or a 0 after the = will be entered/changed
A 0 represents 3 Tonne Limit turned off
A 1 represents 3 Tonne Limit turned on
7. Make the changes as required:
Disabling the 3 Tonne Limit
Enabling the 3 Tonne Limit
8. Save the changes by selecting File > Save
Select 'Save' to save the modified configuration
9. Eject the SD card and insert it back into the Gen 3 Display
When the Gen 3 next boots up, the 3 Tonne Limit will either be enabled or disabled as edited in the data.cfg file.

Do NOT change any other parameters within the data.cfg file. Doing so may introduce gross inconsistencies and negate the Gen 3 abilities to be an effective safety system
