CTX 3030: How do I save my modes on to my PC to transfer them or email to a friend?
1. Plug your CTX 3030 into your PC
2. Open XChange 2 and click the CTX 3030 Collection - All the modes and other data from your CTX 3030 will be displayed in the list.
3. Drag and drop the Items you want to email into the FILE Collection.
4. Click the FILE Collection and check the contents are what you intended to share.
5. Simply click the ‘Export a Minelab file’ icon
The entire FILE Collection will be exported as a single file, and saved in the Downloads folder of your PC. You can then save the file elsewhere or email it to whoever you want.
If you receive a Minelab FILE from someone else simply open XChange 2, select the FILE Collection and then click the ‘Clear the contents of your File collection’ icon.
Then click the ‘Import a Minelab file’ icon.
Then click ‘Choose file’, and browse for the file location. Highlight the file and click ‘Open’ and the Items within it will be displayed in the File Collection.
Drag and drop the items you want to keep into one of your own Collections or straight into your CTX 3030.
