Z3 Coupe (E36/8) Found menu while trying to change clock

While trying to change the clock on my 2001 Z3 Coupe for daylight savings time, I found this...

I have the digital clock above the gear shift w/ two buttons s/r and clock icon.

If I hold both buttons in for two seconds it shows :01

If I hit the BC button on the turn signal lever I can cycle through :01, :02, :03, :04, :05.

:01 - From here I can change the time format from 12 to 24hr

:02 - ?

:03 can change a number from 750 - 1250. I can only guess that I am offsetting something from 75% to 125% but don't know what.

:04 when I hit the s/r button the display flashes LSP, beeps at me, and turns off.

:05 allows me to change from Fahrenheit to Celcius



Does anyone out there know what :02, :03, or :04 does?
