If the yellow LED is on continuously, the battery may have reached the end of its
useful life. Refer to the table below for suggested responses.
The charger can accommodate up to eight batteries. The charger charges a maximum of
four batteries at a time. After a battery begins recharging (as indicated by the green LED
that flashes on one second, off one second), it is typically fully recharged within four hours
at room temperature. After a battery is fully charged, the charger continues to maintain
the full charge on the battery until the battery is removed. Leaving a fully-charged battery
in the charger will not harm the battery.
Remove batteries from the battery charger if the battery charger will be disconnected
from ac power for more than a few days. Do not block the cooling vents at the rear of the
battery charger.
The monitor battery charger only charges four batteries at a time. A battery is not fully
charged until the green LED is on continuously. Do not remove a battery until it is fully
charged, or displays a battery fault.

Something is wrong with the battery or the charger. Remove the battery.
• If the LED goes off, it is probably a battery problem. Insert a new
battery into the same battery well. If the new battery charges correctly,
then the battery has a problem; discard the battery. The battery reorder
number is 008-0647-XX. If the same problem occurs with the new
battery, the charger may need repair. Contact biomedical engineering.
• If the LED does not go off when you remove the battery, it is probably a
charger problem. Unplug the charger power cord, wait at least 5
seconds, then plug in the charger power cord again. Insert a new
battery into the same battery well. If the new battery charges correctly,
then the battery has a problem; discard the battery. If the same problem
occurs with the new battery, the charger may need repair. Contact
biomedical engineering.
WARNING The monitor battery is Lithium Ion. Do not incinerate, submerge,
crush, disassemble, or autoclave. If a battery has been submerged in liquid,
discard the battery properly; do not try to recharge or reuse the battery. Do not
short the battery terminals. Do not try to connect the battery to any device
except the monitor or the monitor battery charger. Do not expose to high
temperature (above 60° C or 140° F). Use only the specified monitor battery
charger.
