Further reducing power consumption
Using both the dimmer and standby mode (Screen OFF) can reduce power consumption further than only using the dimmer.
For setting up standby mode, refer to the following.
M.2.5 Turning OFF the screen after a certain period of time (standby mode)
Setting Example:
When [Dimmer Timer] = 60 seconds and [Standby Mode Time] = 5 minutes:
The screen is dimmed 60 seconds after the last touch screen operation, and enters standby mode (screen turns OFF) 4 minutes later.
If [Standby Mode Time] is shorter than [Dimmer Timer], dimmer settings are ignored. Standby mode (Screen OFF) will not switch to the dimmer.
