Function buttons
The gas density indicator is controlled via 4 function buttons, with each button having
a main and a secondary function. In general, the information printed on the buttons
corresponds to the main function: "ZERO", "LIGHT", "MENU", "ON/OFF". Once the
[MENU] button is active, the secondary function applies. These are, from left to right:
Cursor up "UP / ▲", cursor down "DOWN / ▼", left/right cursor "L / ◀" or "R / ▶" and
"HOME".

The main function is switching the gas density indicator on and off.
If the gas density indicator is already in menu mode, a short press on the [On/
