4.3.10 Menu Item 19: Persistent Time Sense Report
This report allows you to determine if the internal persistent time circuit is
keeping time correctly.

From the service mode steady state, select menu item 19 by pressing the
UP or DOWN ARROW buttons.
2.
Press the UPPER ALARM LIMIT button. The persistent time in seconds
is displayed in the SYSTOLIC and DIASTOLIC displays. Using a watch
or other timepiece, note the time to the nearest second.
3.
Wait 3 minutes from the time you originally noted.

Subtract the first figure you noted from the figure now displayed. The
difference should equal approximately 3 minutes (180 seconds).

4.3.11 Menu Item 20: Reset to Factory Defaults
This function allows the service technician to reset the monitor to the Nellcor
factory default settings (see the Specifications section of this manual).
1.
From the service mode steady state, select menu item 20 by pressing the
UP or DOWN ARROW buttons. Press the UPPER ALARM LIMIT
button.
2.
Verify that the N-3100 emits three short beeps to indicate that the
default settings have been successfully reset to the factory default
values. Any alarm limit that was set to a value other than the factory
default is now lost. The N -3100 automatically exits the menu item and
returns to the service mode. If the reset is successful, the monitor will
beep. If the reset was not successful, an error code will be displayed.
4.3.12 Menu Item 21: Initial Cluster Instrument Number (CIN) Selection
This function allows the service technician to select the initial cluster
instrument number (CIN) address for an N-3100 that is being used in a
stacked configuration.

From the service mode steady state, select menu item 21 by pressing the
UP or DOWN ARROW buttons. Press the UPPER ALARM LIMIT
button. The number 21 is shown in the SYSTOLIC display and the
current hexadecimal CIN is shown in the DIASTOLIC display. If the
displayed CIN is different from the number stored in the N -3100
memory, the CIN will flash.
2.
To select a new CIN, press the UP and DOWN ARROW buttons. New
CIN values must be in the range of 1 to 15.
3.
Once you have selected a new CIN, press the UPPER ALARM LIMIT
button to save the new CIN in the N -3100 memory.
4.
Press the LOWER ALARM LIMIT button to return to the service mode
steady state.
