6.2 Current light level in the room
–
the darker it is in the room, the bigger the number displayed. E.g.,
when it is very light it can be around 25, when it is dark it can be around 60. The current light level is
shown to define the threshold more precisely.
6.3 Tubes BRIGHTNESS Control Evening threshold
This parameter sets the level of the ambient light in the room (refer to the current level shown in the
2nd pair of tubes) when the clock should decrease the brightness (e.g., in the evening)
For example, you would like the clock to decrease it brightness when the light level in the room is
below 40, then set this parameter to 40. When the level will go below 40, the clock will decrease its
brightness.
Press the SET button repeatedly until the desired threshold level for switching for the evening is
shown. The current light level in the room is shown in the middle tubes (6.2) for your convenience.
TIP: It is better to set this up at a light level when you want the clock to decrease its brightness.
Press the MODE button to move to set the brightness level setting.
