1.1 MANUAL OVERVIEW
This manual contains information for servicing the NELLCOR SYMPHONY
N-3100 blood pressure monitor. Only qualified service personnel should
service this product. Before servicing the N-3100, read the operator’s manual
carefully for a thorough understanding of operation.
1.2 WARNINGS, CAUTIONS, AND NOTES
This manual uses three terms that are important for proper operation of the
monitor: Warning, Caution, and Note.
1.2.1 Warning
A warning precedes an action that may result in injury or death to the
patient or user. Warnings are boxed and highlighted in boldface type.
1.2.2 Caution
A caution precedes an action that may result in damage to, or malfunction of,
the monitor. Cautions are highlighted in boldface type.
1.2.3 Note
A note gives information that requires special attention.
1.3 N-3100 BLOOD PRESSURE MONITOR DESCRIPTION
The N-3100 is a noninvasive blood pressure monitor that measures systolic,
diastolic, and mean arterial blood pressure. It also derives the patient’s pulse
rate at the time of blood pressure measurement. The N-3100 is intended for
hospital use to monitor adult, pediatric, or neonatal patients. The N-3100 can
be used in mobile environments when stacked with the N-3000, the N-3200,
or both. When used in mobile environments, the N-3100 must be protected
from excessive moisture such as direct rainfall.
The N-3100 can operate as a standalone monitor or it can be connected to
(stacked with) other NELLCOR SYMPHONY instruments, such as the
N-3000 pulse oximeter, the N-3200 display/printer, or both.
The physical and operational characteristics of the monitor are described in
the operator’s manual and Section 9, Specifications, of this manual.
Figures 1-1 and 1-2 depict the North American and International front panels
of the N-3100 and the names of its displays and controls.

1.4 RELATED DOCUMENTS
To perform test and troubleshooting procedures and to understand the
principles of operation and circuit analysis sections of this manual, you must
know how to operate the monitor. Refer to the N-3100 operator’s manual. To
understand the various Nellcor Puritan Bennett cuffs and hose that work
with the monitor, refer to the individual cuff and hose directions for use.

SECTION 2: ROUTINE MAINTENANCE
2.1 Cleaning
2.2 Periodic Safety and Functional Checks
2.3 Batteries
2.1 CLEANING
Caution: Do not immerse the N-3100 or its accessories in liquid or use
caustic or abrasive cleaners. Do not spray or pour any liquid on the
monitor or its accessories.
To clean the N-3100, dampen a cloth with a commercial, nonabrasive cleaner
and wipe the instrument exterior surfaces lightly. Do not allow any liquids to
come in contact with the power connector, fuse holder, or switches. Do not
allow any liquids to penetrate connectors or openings in the instrument cover.
For cuffs and hoses, follow individual directions for use.
2.2 PERIODIC SAFETY AND FUNCTIONAL CHECKS
The following safety checks should be performed by a qualified service
technician after any repair or opening of the case, upon return of the
instrument from any use outside your institution’s control, or at least every 2
years.
1. Inspect the exterior of the N-3100 and verify that there is no evidence of
damage. Refer to Section 5, Troubleshooting for repair. If the N-3100
cannot be repaired, contact Nellcor Puritan Bennett’s Technical Services
Department or your local Nellcor Puritan Bennett representative.
2. Inspect safety labels for legibility. If labels are not legible, contact
Nellcor Puritan Bennett’s Technical Services Department or your local
Nellcor Puritan Bennett representative.
3. Verify that the monitor performs properly as described in paragraph 3.3.
4. Perform the electrical safety tests detailed in paragraph 3.4. If the unit
fails these electrical safety tests, do not attempt to repair, contact Nellcor
Puritan Bennett’s Technical Services Department or your local Nellcor
Puritan Bennett representative.
5. Inspect fuse(s) for proper rating (AC inlet fuse: 0.8 Amp, 250 Volt). If
necessary, replace as described in paragraph 6.2.
2.3 BATTERIES
Nellcor Puritan Bennett recommends replacing all instrument batteries at
least every 2 years. To replace the batteries, refer to Section 6, Disassembly
Guide.
If the N-3100 has been stored for more than 30 days and has not been
connected to an SPS power supply, charge the battery before use. A fully
discharged battery requires a 14-hour charge for a full charge. A 6-hour
charge is required for 1 hour of operating time. Connect the N-3100 to an SPS
external power supply during storage to ensure that the battery remains fully
charged and the N-3100 is ready for immediate use.
