This is the Notch Indicator... The Left one shows from Notch 1 to 32 and 32 onwards till 39 is shown in another Analog indicator. But here there is a Digital Notch indicator which shows only from Notch 33 to 39. If this had to change it from Analog to Digital it should hav been changed for all the Notches...
