System Settings Menu 

 
From here you can control many “under the hood” global functions of the clock such as setting 
12/24 hour mode, Brightness (manual or automatic), color, clock font, sound volume, Fahrenheit 
or Celsius temperature mode, turn on/off optional RF and Infrared receiver functionality. 
 

User Options Menu. 

 
Very similar to System Settings. In this menu you will be setting misc. options such as what 
clock will say when TALK button is pressed, or how frequently Info Display will appear and 
temperature offset. See below about this option. 
 

Temperature Offset 

 
What is it and 

why it’s needed you might ask?  Can it reverse effects of the global warming? 

Well you see, Xronos Clock components generate some heat. Especially LED matrix. As 
efficient as LEDs are they still get warm. Higher brightness you will choose, the warmer clock 
will get inside.  This is really nothing to be worried about (we are talking about few degrees 
above ambient), however because temperature sensor is embedded in the clock case, it will 
usually show temperature couple of degrees higher than air in your room.  Thus comes 
Temperature offset to the rescue! I recommend setting it to about -2 degrees. If you have 
another thermometer available use it to calibrate Xronos Clock to a correct temperature using 
offset.
