LCD MESSAGE CONTRAST ADJUSTMENT MENU 

 

In some cases, mainly in systems where the message center would be mounted further 

apart from one another or at different angles in the dash, you may want to adjust the contrast of 
the LCD for better visibility.   By default the contrast is set about midway and this setting should 
be acceptable for most applications, but you can change it for individual preference. 
 

The contrast menu is a hidden menu since it typically shouldn’t need adjustment, to get to 

the menu: 
 
Press and hold SW1 while turning the key on.  Release the switch.   
The LCD1 message should display “

setup speed

” and the LCD2 message should read “

setup

” 

To access the hidden contrast menu, press and hold SW2 until “

contrast adjust

” appears on 

both LCD screens, then release SW2.   

Now if you press and hold SW1 a contrast bar will display and the contrast will change while the 

switch is held, the next press and hold of SW1 will decrease the value.  You can continue with 
the press and hold and release to scroll up and down and adjust the contrast to your liking.  

Once happy with the setting; release the switch and the screen will go back to “

contrast 

adjust

” after there is no switch press for about three seconds.  

If you have two LCD message centers use SW2 to adjust the contrast on LCD2 following the 

same method as above.  

After no switch presses for about ten seconds, contrast adjust mode will be exited and you will be 

returned to the next main setup menu.  If you are unhappy with the contrast, simply press and 
hold SW2 to access the menu again from any one of the main setup menu screens.  

 
 
 
 

NORMAL OPERATION AND FUNCTION 
 

Here we will describe the common functions and “normal” operation of the VHX system.  

Please follow the wiring and setup instructions to insure you have your system calibrated and 
connected properly for your application.  Avoiding setup or selecting incorrect options as that will 
cause the gauge readings to be incorrect.

  

 

 
All of the VHX systems have the obvious gauge sweeps, but the biggest difference 

between the VHX series and other analog style gauges are the information or message displays.  
Each VHX system has two message displays, although some systems may have one large 
display.  Display 1 is typically in the speedometer gauge or under it in dual display systems and 
Display 2 is usually under the tachometer.  For systems with a larger single display message 
center, the top half of the large display is considered Display 1 and the bottom half Display 2.   
 
The message displays can display a wealth of auxiliary information as well as warning messages 
and even 16 additional channels with the use of the separately purchased BIM units, bus 
interface modules.   

 

 

You must wire the momentary push button switches in order to access the different 

message screens.  The message displays are accessed using the supplied push-button switches. 
Switch 1 (SW1) will toggle between the speed/LCD1 message displays and Switch 2 (SW2) will 
toggle between the tach/LCD2 message displays.  The switches must be wired to access setup 
menus. It is recommended that you mount them in a spot easily accessible while viewing the 
displays and gauges.  
 
By default the available messages for each message display are:
