CLEANING THE BUZZER
Recommended materials are cotton swabs and pure isopropyl alcohol.
Under certain circumstances, residue will build up on the buzzer located on the MCU
board. This residue can prevent the buzzer from alarming, but can be easily removed.
To remove any residue, refer to Figure 5-1, Cleaning the Buzzer , then proceed as follows:
1. Separate the front and rear enclosures as described in Section 7.2.5 , leaving the
main chassis in the rear enclosure.
2. Inspect the buzzer for any physical damage. If damage is found, discontinue this
procedure and contact Hospira .
3. Moisten the cotton swab with the isopropyl alcohol and clean any residue from the
entire rear surface of the buzzer.
4. Reassemble the pump in the exact reverse order of disassembly, and perform the
PVT in Section 5.2 .
