Battery Maintenance and Care Cardiograph Care and Maintenance
PageWriter TC 70 Cardiograph Service Manual 2-11
If the cardiograph will be stored for more than sixty days without use, fully charge the
batteries, and then remove AC power from the cardiograph, and remove the batteries from
the cardiograph. Store the batteries in a cool, dry location. A set of fully charged batteries
stored outside the cardiograph will need to be recharged every sixty days.
Replacing the Batteries
WARNING Properly dispose of or recycle depleted batteries according to local regulations. Do not
disassemble, puncture, or incinerate the disposed batteries.
WARNING Carefully follow the instructions for replacing the batteries. Only use batteries with
Philips part number 989803160981.
CAUTION When removing the batteries from the cardiograph, the batteries could feel warm to the touch.
How often batteries need to be replaced depends on how well the battery is maintained and
how much it is used. If the batteries are fully charged but lose significant power after only a
few ECGs, consider replacement. For information on ordering replacement batteries, see
“Ordering Options and Upgrades” on page 1-37.
To install the batteries:
1
Unplug the cardiograph from AC power.
2 Open the battery door.
