In the "ENGINE TIMER" Display Mode an "/Hr" will appear in the upper right corner of the display

indicating that the display is shown in hours. When the Engine Timer is running, the "/Hr" in the display

will "blink." The Timer will run when the bus voltage is above 13 volts for a 12-volt system or 26 volts

for a 24-volt system. Note: An alternate installation method is to connect the SC-5 to the battery

through an Oil Pressure Switch. With this installation method, the Engine Timer will run any time you

have oil pressure(regardless of the bus voltage). This allows the SC-5 to be used for bill time.

While in this mode, push and holding the Left Button to display the current bus voltage.
