Cleaning Periodic Safety and Functional Checks Batteries
CLEANING Caution: Do not immerse the N-3200 in liquid or clean with caustic or abrasive cleaners, chlorofluorocarbons, or petroleum solvents. Do not spray or pour any liquid on the N-3200. To clean the N-3200, dampen a cloth with a commercial, nonabrasive cleaner and wipe the 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.
2.2
PERIODIC SAFETY AND FUNCTIONAL CHECKS The following checks should be performed at least every 2 years by a qualified service technician. They should also be performed whenever the N-3200 is repaired, has had its covers removed, or has been returned from outside your institution’s control. 1.
Inspect the exterior of the N-3200 for damage.
2.
Inspect safety labels for legibility.
3.
Verify that the instrument performs properly as described in Section 3 Performance Verification, paragraph 3.3.
4.
Perform the electrical safety tests listed in Section 3, Performance Verification, paragraph 3.4.
5.
Inspect the fuses for proper value and rating (battery fuse: 2.5 amp, slow blow, 5 x 20mm; AC inlet fuse: 2.0 amp, slow blow, 5 x 20mm) as discussed in paragraphs 6.2 (AC inlet fuse) and 6.3 (battery fuse).
If the N-3200 has any damage or illegible labeling, or if it fails to perform any of the tests or has improper fuse values, the repairs or corrections must be made before the N-3200 is returned to the user. Contact Nellcor Puritan Bennett’s Technical Services Department or your local Nellcor Puritan Bennett representative for further assistance. 2.3
BATTERIES Nellcor Puritan Bennett recommends replacing instrument batteries every 2 years. To replace the batteries, refer to Section 6, Disassembly Guide . Follow local governing ordinances and recycling instructions regarding disposal or recycling of battery or other device components. If the N-3200 is to be stored and not used for more than 30 days, you may ensure that the battery remains fully charged by connecting it to a functional AC outlet with the unit turned on and the AC power switch on the rear panel in the ON position.

Introduction Equipment Needed Performance Tests Safety Tests
INTRODUCTION This section describes performance verification and safety testing for the N-3200. The following tests are designed for an overall assessment of N-3200 operation and safety and should be performed by a qualified service technician. The tests can be performed without removing any exterior covers. The battery performance and battery recharge tests should be performed before monitor repairs whenever the battery is suspected of being a source of the problem. All other tests should be performed whenever the N-3200 is repaired, has had its covers removed, or has been returned from outside your institution’s control. If the N-3200 fails to perform as specified in any test, repairs must be made before returning the unit to the user.
