The back light lamp is managed by the Gen-set control module, which switches off the back
light after a programmable time (P.492) if no buttons are pressed in the meantime. Press any
button to switch the lamp ON again, (we recommend using the Esc/SHIFT button as it
has no function when used alone). This function can be disabled by setting parameter P.492
to 0.
Depending on the environmental temperature conditions, the contrast may require adjustment
in order to view the display correctly.
Press in sequence the Esc/SHIFT button + LEFT to reduce the contrast (lighten),
press the Esc/SHIFT button + RIGHT to increase it (darken).
