The ENTER key is used to enter or change data (such as an alarm threshold set-
ting). You should become familiar with the use of this key, since it serves many
purposes in operating the Health EM. The ENTER key has two basic modes of
operation, each of which is explained below.
• Press and release
In general, each digit in a value is changed separately. The “active” digit
(the one which is currently ready to be changed) flashes on and off in the
display. Pressing and releasing ENTER cycles through all available digits
in a value, making each digit active in turn. Each time you press and
release ENTER, the next digit becomes active. When you first begin to
change a value, the leftmost digit will be active. Pressing and releasing
ENTER will cause the second digit (from the left) to become active, and
so on. When you get to the last digit in a value, pressing and releasing
ENTER makes the first digit (the leftmost digit) active once again.
