Setup

To calibrate the monitor you must open and then perform some disassembly to reach the
necessary calibration points.
1. Before you begin disassembly, charge the battery pack for at least 8 hours to ensure it
is fully charged.
2. Remove any options attached to the monitor. If either the SpO
is attached to the monitor, remove it before starting the calibration. The calibration
procedures in this section are for the three monitor boards only.
3. Remove the battery pack.
4. Disconnect the ac power adapter from the monitor's right side panel power input
connector.
All test equipment must be calibrated to function within parameters specified by
the manufacturer, and be traceable to a national calibration standard.
Caution All calibration, service, and repair must be done at a static-protected
work station. Failure to protect against damage due to static discharge can
damage components in the Propaq CS monitor.
Caution Refer to "Repair procedures"
reassembly procedures. Failure to follow disassembly procedures may result in
damaged internal parts.
