22 FONIX FP35 Hearing Aid Analyzer
There are three different types of menu items: local variables that are only
active within the current screen, global variables that are available in all screens
that use it, and resetable variables that change to a default value when [RESET]
is pressed or the unit is first turned on. Resetable variables can be local or
global. Most global and resetable variables are available in the Default Settings
menu. Local variables are not available in the Default Settings screen.
You can always tell what type a variable is by looking at the dash sequence next
to it in one of the menus. Local variables use a series of small dots. Global vari-
ables use a series of large dots. Resetable variables use a series of short dashes.
See Figure 2.1.2.

Details on the behavior of menu items:
Local variables are not available in the Default Settings menu. When the analyz-
er is first powered on, local variables are set to a factory defined default setting,
but they are not normally changed back to the default setting when [RESET] is
pressed. (There are some exceptions.)
When you change a resetable variable in the Default Settings menu, it will
impact that variable in all local menus where it is available. However, chang-
ing a resetable variable in a local menu will not change its value in the Default
Settings menu. When [RESET] is pressed, the local variable will revert back to
the value defined in the Default Settings menu.
