1968-77 chevy corvette gauge

Advertisement

The Odyssey series clock displays the current time in 12 hour format. The high
brightness display matches our other Odyssey, STR, and VFD3 series gauges and has
the same night brightness dimming capability.
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:
The remote mounted red and black push buttons will be used to set the clock. The
BLACK "set" button advances hours, the RED "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.
