Caution The frequency recommendations in the following table do not supersede local requirements. Always perform locally required testing in addition to the testing in this chapter.

Maintenance Procedure		Frequency
Routine Safety and Operational Checks
• Visual Inspection of exterior for damage		Before use.
• Inspection of labels for legibility		Before use.
Cleaning and Disinfecting		According to your institution’s policy or
		between each patient. For complete
		cleaning instructions, see the Instructions for
		Use provided with your monitor.
Maintaining the Battery
•	Charging	As needed.
•	Reconditioning	When the Max Error is 10% or greater.

Warning The monitor must be connected to a three-wire, grounded hospital-grade receptacle. Do not remove the grounding connector from the power plug or use extensions cords or adapters of any type.

If there is any doubt about the integrity of the protective earth conductor arrangement, operate the device on internal battery power until the AC power supply protective conductor is fully functional.

Measure the device's leakage current whenever an external device is connected to the serial port. Leakage current must not exceed 100 microamperes. See “Safety Tests” on page 3-22.

Warning MR-unsafe!

Do not expose the device to a magnetic resonance (MR) environment.

•The device may present a risk of projectile injury due to the presence of ferromagnetic materials which can be attracted by the MR magnet core.

•Thermal injury and burns may occur due to the metal components of the device which can heat during MR scanning.

•The device may generate artifacts in the MR image.

•The device may not function properly due to the strong magnetic and radio frequency fields generated by the MR scanner.

•Max Error: The expected margin of error in the state of the charge calculation. The Max Error value is the difference between the Relative Charge value and the Absolute Charge value.

•Relative Charge: The predicted remaining battery capacity, expressed as a percentage of Full Capacity. The value in the Relative Charge field decreases as the battery ages. The Battery Status icon is a graphic representation of the Relative Charge.

•Absolute Charge: The predicted remaining battery capacity, expressed as a percentage of

Design Capacity.

•Full Capacity: The predicted capacity of the battery when it is fully charged. The value in the Full Capacity field decreases as the battery ages. The difference between the value in the Full Capacity field and the value in the Design Capacity field is an indication of battery condition.

•Design Capacity: The capacity of a new battery.

Maintaining the Battery

Reconditioning the Battery

Reconditioning the battery reduces the Max Error value, and in turn, increases the accuracy of the Relative Charge. Philips recommends that you condition the battery by fully discharging and recharging it when the Max Error is 10% or greater.

	Step
	1	Open the Battery Info window. See “Viewing Battery Information” on page 2-2.
	2	Disconnect the monitor from the power source.
	3	Select Recondition.
		The Relative Charge percentage will decrease to 0%.
	4	When the monitor shuts down, connect the monitor to the power source and allow
		the battery to recharge to 100%.
	5	Repeat step 1 through step 4.
		Note — If the battery does not recharge after four reconditioning cycles, replace it.

Replacing the Battery

Replace the battery if the following conditions occur:

•After reconditioning, if the monitor operates for less than one hour on a fully charged battery before the low battery (Low Batt) alarm occurs, or

•The Max Error cannot be brought <= 8% after several recondition cycles, or

•The Full Capacity is 50% or less of the Design Capacity.

For information about replacing the battery, see “Removing the Battery” on page 5-3.

Warning Dispose of used batteries in an environmentally responsible manner. Do not dispose of the battery in normal waste containers. Consult your hospital administrator to find out about local arrangements.

Battery Messages and Alarms

The condition of the battery is reported by technical alarms and error codes.

Technical Alarms

The following battery technical alarms appear in the message area:

•Low Batt — Remaining battery power is less than 30%.

•Extreme Low Batt — Remaining battery power is less than 21%.

Error Codes

An error code (for example, 257 System Error, indicating Battery charger power failure) appears in the Error Log. To view the Error Log, see “Viewing, Printing, and Exporting the Error Log” on

page 4-38. For a complete list of error codes and actions to take, see Chapter 4, “Troubleshooting.”
