Checkpoints can be set up automatically or manually. If an automatic schedule is
selected then day and time information must be configured for these checkpoints to
occur. Checkpoints have a negative effect on system performance. This effect
increases as checkpoints are added. Use them judiciously.

fields listed below:
■ Description – Enter a short description of the checkpoint. This is a mandatory
field.
■ Days – Select the days on which you want the checkpoint to be created. Enter a
“Y” for each day that is scheduled. The space bar will leave current data in tact
and skip to next day. [Enter] key will skip to the next field.
■ AM Hours – Select the AM hours at which you would like the checkpoint to be
created. Enter a “Y” for hour that checkpoint will be taken. The space bar will
leave current data in tact and skip to next hour. [Enter] key will skip to the next
field.
■ PM Hours – Select the PM hours at which you would like the checkpoint to be
created. Enter a “Y” for hour that checkpoint will be taken. The space bar will
