Caution: Do not immerse the NPB-195 or its accessories in liquid or clean
with caustic or abrasive cleaners. Do not spray or pour any liquid on the
monitor or its accessories.
To clean the NPB-195, 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. Wipe sensor
cables with a damp cloth. For sensors, follow each sensor's directions for use.
The following checks should be performed at least every 2 years by a qualified
service technician.
1. Inspect the exterior of the NPB-195 for damage.
2. Inspect safety labels for legibility. If the labels are not legible, contact
Mallinckrodt's Technical Services Department or your Mallinckrodt
representative.
3. Verify that the unit 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 the NPB-195. Contact
Mallinckrodt's Technical Services Department or your local Mallinckrodt
representative.
5. Inspect the fuses for proper value and rating (F1 & F2 = 0.5 amp slow
blow).
Mallinckrodt recommends replacing the instrument battery every 2 years. When
the NPB-195 is going to be stored for 3 months or more, remove the battery prior
to storage. To replace or remove the battery, refer to Section 6, Disassembly
Guide.
If the NPB-195 has been stored for more than 30 days, charge the battery as
described in paragraph 3.3.1. A fully discharged battery requires 14 hours in
standby, or 18 hours if in use, to receive a full charge. The battery is being
charged anytime the instrument is plugged into AC.
