 keys to select the desired light behavior. Options are Leave

Flash (flash the backlight according to the Flash Pattern setting).
Flash Pattern, On Time, Off Time
Flash Pattern defines the pattern that is used for this object when
the Light mode is set to Flash. Each object uses a 32 step Flash
Pattern. Each step in the 32 step flash pattern defines whether
the backlight is on or off for the durations specified in the On
Time and Off Time settings below. The 32 step Flash Pattern
consists of eight blocks with four steps for each block. The Flash
Pattern within a four step block is defined using the characters
0-9 and A-F. Figure 8 illustrates the 16 individual flash patterns
for each four step block.
