Battery Maintenance and Care
The cardiograph has two removable lithium ion batteries that supply power to the cardiograph
during mobile use, and power the cardiograph printer while it is plugged into AC power.
For optimal battery performance:
Only use Philips Medical Systems lithium ion batteries (Philips part number
989803160981) with the cardiograph.
Before initial use, fully charge the batteries for five hours before operating the cardiograph
without AC power. Regularly and consistently charging the batteries will prolong battery
life.
Charging, storing, or using the batteries at temperatures above 50
o
C (122
o
F) can damage
the batteries and reduce overall battery life.
Check the battery power indicator on the Status Bar. Tap the battery icon on the Status Bar
for information on remaining battery power, see “Battery Power Indicator” on page 1-23.
Always charge the batteries when the cardiograph is not in use. Plug the cardiograph into
AC power. Ensure that the green AC power indicator light on the front of the cardiograph
is lit. The batteries will charge while the cardiograph is in use, but will charge at a slower
rate.
Operate the cardiograph, charge the batteries, and store the batteries at a room temperature
of 25
o
C (77
o
F) or lower. Exposure to higher temperatures may reduce battery life,
damage the batteries, and degrade overall cardiograph performance.
