There are five setting displays on the timer face:
The center character is a letter: S for seconds, M for minutes and H for hours.
The two digits to the left of the letters are for whole units.
The two digits to the right of the letters are for fractions of units.
For example: 01M10 = 1 minute and 10 seconds
18S00 = 18 seconds
04S50 = 4.5 seconds
To adjust the digits press the buttons located directly over and under each digit. The top
button increases the number, whereas the bottom button decreases it.
When the Lumitron is powered on for the first time that day, the timer will count up from zero
to the set point. For every exposure afterwards, just simply turn off the light rocker switch and
turn back on. This will start the LED lights and begin the count down again.
