Setup Mode

The speedometer full scale deflection 
setting can be changed using the Setup 
Mode (see Figure 1). Use this option only 
if you have reason to believe that your 
setting is wrong. Setting an incorrect 
value in this menu can result in extremely 
inaccurate performance of the 
speedometer. To access the Setup Mode, 

press and hold

  both the “Up” and 

“Down” buttons while turning on the 
instrument. 

The display will show “*SETUP*”. 

Briefly pressing the “Mode” button will 
change the display to the setting menu. 

The “Up” and “Down” buttons are used to 
modify the setting.
