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.

By activating the [MENU] button, the menu mode is enabled. If the gas
density indicator is already in menu mode, depending on the display, "L" or
"R" will be executed. If the button is pressed for longer, after 2 seconds the
cursor switches (right ◀ or ▶ left).
Inputs are confirmed with the [MENU] button.
