131. s on the degree of discharge the storage temperature and the length of time the battery was stored in a discharged state A permanently damaged battery cannot be recharged to full capacity When the battery discharges below the acceptable level while the infuser is operating the alarm sounds and the battery icon flashes Although it is not recommended to continue operating the infusion system on battery power at this point the battery continues providing power until discharged At this point the infuser enters the DEAD BATTERY mode and a continuous audible alarm sounds for three minutes followed by the infuser powering itself off CAUTION As soon as the LOW BATTERY alarm occurs connect the infuser to AC power Recharging occurs any time the infuser is connected to AC power It is recommended that the infuser be connected to AC power whenever practical to maximize available battery charge during transport or ambulation The infuser does not have to be on for the battery to recharge Recharging while the infusion pump is operating is program dependent LifeCare PCA with Hospira MedNet 5 24 Technical Service Manual Section 6 TROUBLESHOOTING This section contains information on technical assistance Diagnostic Mode alarm messages and error codes and troubleshooting procedures 6 1 TECHNICAL ASSISTANCE For technical assistance product return authorization and to order parts accessories or manuals within the United States
