Fig. 31. Jumper location (backlight ON position) 
The figure above shows the location of the jumper. To change 
jumper position, disconnect the connector first, then pull off 
jumper with tweezers or pincers and move to new position. 
When the jumper is enabled (ON-position) the backlight will 
be activated with the first key press of any of the eight 
operating keys. If no entries are made for approximately two 
minutes, the backlight turns itself off automatically until the 
next key is pressed again.

When the jumper is disabled (OFF-position), the backlight is 
permanently deactivated.  
The contrast of the display can be adjusted using the  
potentiometer at the rear of the unit.
