Using this function
＞
The high-altitude region support functions have three operation levels,
with the appropriate level being set up by the installer until the abnormal
sound problem is solved. The desired level can be specified at the right
bank of dipswitches (No.2 and No.3) on the computer board.
If the abnormal sound problem persists even with a “Level 3” setting, please contact our
Technical Service Department. for advice. Note that there are many high risks associated with
manually changing the manifold pressures.
