Energy saving mode
To reduce the energy consumption to a minimum, OpenStage phones offer an energy saving
mode. The display backlight (phone and Key Module, if attached) is switched off after a
configurable timeout.
With OpenStage 40, the main display and key module backlight will be switched off after 90
seconds of inactivity (firmware version V2R0 onwards). Readability even without backlight is
ensured by the transflective display.
With OpenStage 60 and 80, the timer is configurable by the administrator (Local Functions
> Energy saving); the timeout ranges between 2 and 8 hours.
