If you have connected the optional cartridge sensor
to your unit, a fuel cartridge will appear in the
display as soon as a predetermined amount is
reached.
Always keep a reserve fuel cartridge at the ready. The
cartridge need only be changed when the message
“Please change cartridge“ appears in the display.
The standard display will be restored after about 30
seconds. Alternatively, you can return to the standard
display by pressing >> again.
By pressing >> for approximately 2 seconds, you will
obtain the language menu (see Chapter 5.5).
