The gauge requires an oval hole 1-7/16” high x 3-1/16” wide.  It should be inserted into the opening from 

the front and the 2 L-clamps will be installed from the back.  Tighten a nut on each of the L-clamps so that the 
gauge is secure.  Gauge depth to the back of the case is 1”.  Gauge depth including the mounting studs is 1-7/8”. 
 
Operation: 

The gauge needs the red, orange, and black wires connected to operate.  The red wire should have 

switched 12 volt power from an ACC. point on the fuse panel.  The orange wire should have constant 12 volt 
power.  The black wire should be connected to a good ground point.  When the blue wire has 12 volts, it will dim 
the display for night viewing. 
 
Setting the time: 

Using a small, thin object such as a toothpick or pin, press “set” buttons through front lens access holes.  

The access holes are on the left and right sides of the lens.  Left “set” button advances hours, right “set” button 
advances minutes.  Each time that you make a change to either the hours or minutes, the seconds are reset to 
zero.   
 
Adjusting the accuracy: 

The clock is accurate to +/-2 minutes a month as it is sent.  It can be tuned for better accuracy if desired.  

Press and hold both of the set buttons for several seconds.  The clock will display “C  0”.  The “C” indicates that it is 
in the calibration mode and the second number is the current calibration value.  The calibration value indicates the 
number of seconds to add or subtract each day.  The clock can be adjusted from +7 sec/day to -7 sec/day. 
Press the minute set button to change the cal value.  Press the hour set button to return to normal clock operation.
