The system is capable of switching automatically between day / lunch break / night settings using the time 
parameters set in this Mode. To change from manual to automatic night switching the console presses [PRG] 
[TRF/FL]  *. Pressing * toggles between the 2 modes. 
If a Function key has been set to function 52 then pressing this key will change from Day to night mode by one 
touch but will not change between Automatic and Manual switching.
