Cleaning
Warning Do not immerse the monitor 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 monitor, 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 or switches. Do not allow any liquids to
penetrate connectors or openings in the instrument. For cables, sensors and
cuffs, follow the cleaning instructions in the directions for use that accompany
these accessories.
Periodic Safety And Functional Checks
The monitor requires cleaning, battery maintenance and NiBP performance
and verification check every two years. The following performance
verification tests may be used following repair or during routine maintenance
(if required by your local institution).
1. Inspect the exterior of the monitor for damage.
2. Inspect labels for legibility. If the labels are not legible, contact Philips’
Response Center or your local Philips representative.
3. Verify that the NiBP performs properly as described in “Verification of
Pneumatic System” on page 21.
Battery
If the monitor has not been used for a long period of time, the battery will
need charging. To charge the battery, connect the monitor to an AC outlet, or
external DC supply in the case of the A3, as described in “Battery Charge” on
page 13 or the “Setup and Use”
chapter of the User Guide .
Note Storing the monitor for a long period without charging the battery
can degrade the battery capacity. A complete battery recharge
requires 8 hours.
