ter explains how those properties are changed and how new

Edit Subject view
From the Subject Manager choose the Add New Subject ac-
tion and tap on the Do Action button. This enters the Edit Sub-
ject view shown in Figure 40
The ID field is mandatory and must be unique, since it identi-
fies the subject. If you try to add two subjects with the same
ID to
Powertimer SW-300 , it will complain and does not allow
that. The ID should be the social security number of the sub-
ject, since that is most likely going to be unique even in the fu-
ture.
The Surname , First Name and Middle Initial identify the sub-
ject in the lists and selectors of Powertimer SW-300 . If you
have multiple subjects with the same last name and initials
within the same test group, you should use numbers as mid-
dle initials to separate them from each other. It is possible to
have multiple subjects with the same last name and initials, but
it will make things more complicated, since you cannot know
which of them is going to be tested next:
• Doe, John J and Doe, Joe J will both be shown as Doe, JJ .
To make things easier you can name them Doe, John 1 and
Doe, Joe 2 (or Doe, John A and Doe, Joe B ), so they will be
shown as Doe, J1 and Doe, J2 (or Doe, JA and Doe, JB ).
If the subject is female, tap on the Sex selector and change
sex to Female .
Changing birth date
The Birth field of Edit Subject view shows the birth date of the
subject, or unspecified if the birth date is not set. Birth date
must be selected before the subject can perform any tests. To
change the birth date, choose the
Change Birth action from
the action selector and tap the Do Action button. This enters
the Date Picker view shown in Figure 41.
Tapping on the up and down arrows at the top right corner
changes the year (it takes some time to set the age of a 75-
year old subject) and tapping on the left and right arrows
at the top left corner changes the month. After the year and
month are located, tap on the day in the calendar and tap
Save & Exit to save changes and return to the Edit Subject
view.
