New Features for this Release
If your CP 100 electrocardiograph has a serial number of 10020000, or greater, or your
CP 200 electrocardiograph has a serial number 20020000, or greater, this update
describes the changes in the operation of your electrocardiograph.
If your electrocardiograph has a serial number that is lower than 1002000 or 2002000, and
your device was recently serviced, it may contain some or all of these new features
depending on the scope of the services performed.
This document supplements information in the following manuals:
• CP 100 12-Lead Resting Electrocardiograph Directions for Use (mat. 708794)
• CP 200 12-Lead Resting Electrocardiograph Directions for Use (mat. 708793)
• CP 200 Spirometry Option Directions for Use (mat. 708795)
Battery Deep-Discharge Disconnect Added
A battery deep-discharge disconnect has been added to reduce the likelihood that your
CP 100 or CP 200 electrocardiograph will operate on a deeply discharged battery. The
disconnect prevents permanent damage to the battery when the battery is left uncharged
for long periods of time.
This functions automatically when the electrocardiograph battery voltage is less than
5.25V in sleep mode. Once a battery disconnect has occurred, the electrocardiograph will
not operate on battery power until it is charged to 6.2V or higher. This also protects the
electrocardiograph from operating on a malfunctioning battery that cannot be charged to
6.2V or higher.
Reset Button
If the electrocardiograph stops functioning, you can press and hold the Power On/Off key
for approximately 7 seconds to restart the electrocardiograph. Release the key once the
restart begins. The key is located on the upper left of the electrocardiograph keyboard.
