Learning the Touchscreen
To save power and ensure long product life, the touchscreen display has a few features
that can be changed to reduce screen brightness and initiate a Screen Saver mode.
High / Low button
: high or low screen brightness, preset values.
Screen Saver
: By pressing the Screen Saver button “on” this will
automatically enter screen saver mode after 15 minutes. At this time, the screen will be
completely blank (ie. black). The illuminated Caron logo (see Equipment Overview
section) shows that the unit is powered on and functioning. To wake-up the touchscreen,
simply press anywhere on the touchscreen and the main screen will display. If the unit
has an alarm condition, the touchscreen will not go into screen saver mode. If an alarm
condition occurs while in screen saver mode, the display will automatically wake up and
display the alarm.
