If an invalid tone is heard instead of the triple beep, the current settings were
not changed. An invalid tone is a single low-pitched tone.
Note : Current values will not be stored in memory as institutional defaults if
power is interrupted before exiting this menu option.
Note : When the operator changes an alarm limit to a value other than a
institutional default value, a decimal point is displayed to the right of
the parameter whose alarm limit was changed.
Menu Item 10 (Restore Factory Default Settings as Power-On Default)
Menu item 10 resets the N-550 to factory default settings as shown in Table 4,
three confirmation tones will be heard.
After menu item 10 has been selected, cycle power to the N-550 and verify
