BACKLIGHT ON/OFF
Enable or disable backlighting.
When enabled the backlighting only comes on when keypresses are made or when the rotary encoder is
used, at which point the backlighting will illuminate for 5 secs.
Press the rotary encoder switch at any time to illuminate the backlighting.
On power up the unit defaults to backlighting ON.
The backlighting intensity dynamically reduces when the DC Input >18Vdc. This is to help preserve circuit
stability & system integrity.
24.5Vdc and over DC Input (this is over spec!) the backlighting is automatically disabled.
