discharge and charge. . Batteries should be conditioned regularly to maintain their useful
life.

Condition a battery once when it is used or stored for 3 months, or when its
operating time becomes noticeably shorter.

The actual battery capacity will decrease over time with use of batteries. When a
monitor operates on batteries that have been used before, the full capacity battery
symbol does not indicate the capacity and operating time of this battery can still
fulfill battery specifications in the operator’s manual. When conditioning a
battery, please replace the battery if its operating time is significantly lower than
the specified time.
To condition a battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring or measuring.
2. Insert the battery in need of conditioning in the battery slot of the monitor, and leave
the other slot empty if your monitor has two slots.

hours.

5. Apply AC power again to the monitor and allow the battery to charge uninterrupted for
10 hours.
6. This battery is now conditioned and the monitor can be returned to service.
