NOTE: 

.

1. When checking the input signals (off, tail, low-beam or high-beam), turn the ignition switch to the "ON" 

position in order to disable the headlamp automatic shutdown function. However, the titles on the 
M.U.T.-II/III screen will not be highlighted as this has nothing to do with actual lamp operation.

2. For checking item "HEADLAMP HI", the M.U.T.-II/III displays "OFF" on the item No.2 "DIMMER SW" 

when the headlamps are at high-beam. Therefore, the M.U.T.-II/III should display "ON" momentarily when 
the dimmer switch is operated.
