Operation and Calibration

C.  The displays will be similar to those below. This is for AM/PM

selection.

      If the AM/PM is correct as indicated by the AM/PM lamps, then

press ENTER and the displays will go to those in Step D.

      If the AM/PM is incorrect, use the u or down arrow keys to select

the proper one and then press ENTER.

D.  The displays will be similar to those below. These are for the day

selection.

      If the day is correct, press ENTER and the growth chamber will

return to regular operation and the setting of the clock is complete.

      If the day is incorrect, use the up or down arrow keys to select the

day. While using the up or down arrow keys, observe the seven
day-of-the-week lamps for selecting the correct day. After the
correct day has been selected, press ENTER and the growth
chamber will return to normal operation and the setting of the
clock is complete.

2.   Set Key 

- Pressing this key will change the displays to one of the

combinations shown below.

      At this time, the user can select the growth chamber to operate in the

PROGRAM mode or CONTINUOUS mode.

      If CONT is displayed, and you wish to change to PROG, press the up

arrow key. The displays will return to their normal operation of
showing time and temperature. Also the continuous lamp will
extinguish and the PROGRAM lamp will illuminate. The growth
chamber will automatically determine the programmed set point
temperature and light status for the present time and day of the week.
