Maverick specific CMT faults
Slow key function
When reaction on a keypress takes around 3 seconds, measure following voltage:
Check VREF=1.5 VDC at C109. If the voltage is lower than 1.4 VDC, probably the capacitor C109 is faulty.
If the fault persists after changing C109, check VREF line between Ccont N201 and Cobba N100 for disconnections or shorts.
Also refer to chapter CMT (MA4) faults.
