Caution
a
Your cardiograph requires the battery to be installed for
proper operation-even if the cardiograph is plugged into
AC power, it cannot print an ECG report without the
battery. For information about replacing or installing
the battery, refer to Appendix A, Setting up Your
Cardiograph for the First Time.
The sealed lead-acid battery used in the PageWriter 100
will provide optimum life when the unit is continuously
connected to AC power and fully charged after each
use. A depleted battery requires 16 hours of continuous
charge time to fully charge. Because it is not always
possible to allow a full charge cycle between uses, the
PageWriter 100 was designed to charge a depleted
battery to 90% of its capacity in approximately 7 hours.
Repeated undercharging of the battery will damage the
battery and reduce battery life.
Note
d
Hewlett-Packard recommends that the cardiograph be
plugged into AC power whenever possible to maximize
battery life.
Battery life varies by how the battery is maintained and
how much it is used. For improved battery life, keep the
instrument plugged in when not in use. If the battery
has been fully charged and requires recharging after a
few ECGs, consider replacing it. Use only HP battery,
part number M2460A.
