2.3 Cleaning
The NPB-40 requires no routine service or calibration. The performance
verification tests in Section 3, Performance Verification, may be used
following repairs or during routine maintenance (if required by your local
institution).
Warning: The NPB-40 uses four "AA" cell alkaline batteries for
operation. If batteries are not replaced when recommended or are
not disposed of properly, serious personal injury or damage to the
NPB-40 could result.
Caution: When inserting the positive end of each battery, exercise
caution to not damage the small coiled spring contact.
Nellcor Puritan Bennett recommends that you comply with the following
guidelines for battery replacement and battery disposal as a minimum.
Caution: The NPB-40 could be damaged by batteries that are left
unused in the unit and begin to leak. Never store the NPB-40 with
the batteries installed for a prolonged period of time.
NPB-40 batteries should be replaced whenever a low battery indication is
observed on the unit. Remove the batteries if you will be storing the NPB-40
for longer than one month. Refer Figure 2-1 for replacing the batteries.
Note: For easier battery installation, insert the negative end of the battery
first when installing each battery.
