Routine Safety and Operational Checks

Philips recommends that you regularly:

• Visually inspect the monitor exterior for damage.

• Inspect the monitor labels for legibility.

If the labels are not legible, contact the Philips Customer Care Center or your local Philips representative.

Philips recommends that you perform certain test and verification checks at least once a year and after each repair. For complete information on performing verification testing and checks, see Chapter 5, “Performance Verification Testing.”

Performing Routine Maintenance

SureSigns VS2 Vital Signs Monitor Service Guide 3-1

Cleaning and Disinfecting

To clean or disinfect your SureSigns VS2 vital signs monitor, use only the approved cleaning agents listed in this chapter.

Warning Do not use unapproved cleaning or disinfecting agents. Even small quantities of some cleaning

agents will damage the monitor or external power supply.

Do not use abrasive cleaners or strong solvents such as acetone or acetone-based compounds. The warranty does not cover damage caused by using unapproved substances.

General Guidelines

Keep the monitor, cables, external power supply, and accessories free of dust and dirt. After cleaning and disinfecting, check the equipment carefully. Do not use the monitor if you see signs of deterioration or damage.

If you need to return any equipment to Philips, clean and disinfect it first.

Follow these general precautions:

• Always dilute cleaning agents according to the manufacturer’s instructions or use the lowest possible concentration.

• Do not allow liquid to enter the case.

• Do not immerse any part of the equipment in liquid.

• Do not pour liquid onto the system.

• Never use abrasive material (such as steel wool or silver polish).

• Do not autoclave, steam sterilize, or ultrasonically clean the monitor or cables.

• Do not use bleach on electrical contacts or connectors.

• Do not use alcohol on the patient cables. Alcohol can cause the plastic to become brittle and fail prematurely.

Caution If you spill liquid on the exterior of the monitor or external power supply, use a clean cloth to dry

them. If you believe the liquid may have gotten inside the monitor or external power supply, contact your biomedical engineer, who can verify the performance and safety of the equipment.

Cleaning and Disinfecting the Monitor

To clean the monitor:

Step

1 Dampen a soft cloth with mild soap and water.

2 Wring any excess moisture from the cloth and gently clean the monitor.

Performing Routine Maintenance

3-2 SureSigns VS2 Vital Signs Monitor Service Guide

Cleaning and Disinfecting

To disinfect the monitor:

Step

1 Dampen a soft cloth with any of the following:

• Isopropyl alcohol (70% solution in water)

• Sodium hypochlorite (chlorine bleach), 3% solution in water

• Ammonium chloride solution, <0.2% solution

2 Wring any excess moisture from the cloth and wipe the monitor to disinfect it.

Cleaning and Disinfecting the Cables and External Power Supply

Caution Do not use alcohol to clean the cables. Alcohol can cause the cables to become brittle.

To clean the cables and external power supply:

Step

1 Dampen a soft cloth with alcohol-free hand soap.

2 Wring any excess moisture from the cloth and gently clean the cables and

external power supply.

3 Clean the areas again with damp cloth moistened with water only.

To disinfect the cables and external power supply:

Step

1 Dampen a soft cloth with sodium hypochlorite (chlorine bleach), 3% solution in

water.

Caution: Sodium hypochlorite may discolor the cable.

2 Wring any excess moisture from the cloth and gently clean the cables.

3 Clean the areas again with damp cloth moistened with water only.

Cleaning the Barcode Scanner

To clean the scanner:

Step

1 Disconnect the scanner from the monitor.

2 Dampen a soft cloth with water (or a mild detergent-water solution). Wring any

excess moisture from the cloth.

3 Wipe the surfaces of the scanner.

If a detergent solution is used, rinse the scanner with a soft cloth dampened with water only.

Reading performance may degrade if the barcode scanner’s window is not clean. If the window is visibly dirty, or if the scanner isn’t operating well:

Step

1 Dampen a soft cloth or lens tissue with water (or a mild detergent-water

solution). Wring any excess moisture from the cloth.

2 Clean the window.

If a detergent solution is used, rinse the window with a soft cloth dampened with water only.

Caution Do not submerge the barcode scanner in water. Do not use abrasive wipes or tissues on the

scanner’s window — abrasive wipes may scratch the window. Never use solvents (for example, acetone, benzene, ether, or phenol-based agents) on the housing or window. Solvents may damage the finish or the window.

Maintaining the Battery

About the Battery

The rechargeable lithium ion battery used in the monitor is a smart battery with built-in circuitry that communicates battery status information to the monitor. Battery power lasts a minimum of four hours of continuous monitoring with no printing and one NBP measurement every 15 minutes.

Observe these guidelines:

• If a battery shows damage or signs of leakage, replace it immediately.

• Never use a faulty battery in the monitor.

• Never dispose of the battery in a normal waste container.

• Never leave a battery inside the monitor if it is not used for a long period of time.

• Never store a battery that is more than 50% charged.

Battery Status Indicators

Battery Status

Charging LED

Please enter the password:

512

Cancel

You can check the status of the battery (level of charge) by using:

• The Battery Status pane

• The Charging LED

• Battery messages and alarms (see “Battery Messages and Alarms” on page 3-6).

The Battery Status pane at the bottom of the main screen indicates the remaining charge in the battery.

The color of the Charging LED on the front panel indicates how much charge remains on the battery:

• Green: The battery is at least 90% charged.

• Flashing Green: More than 30% charge, but less than 90%.

• Yellow: More than 21% charge, but less than 30%.

• Flashing Yellow: More than 12% charge, but less than 21% charge.

• Off: The monitor is in Deep Sleep, the battery has less than 12% charge, or the battery is removed.

Charging the Battery

When the monitor is connected to AC power, the battery begins charging.

When you first receive the monitor, the battery charge may be low. Connect the monitor to an AC power source before using it on battery power alone.

You can recharge the battery while the monitor is in use. If the monitor is not in use, a complete battery recharge requires less than four hours.

Maintaining the Battery

Reconditioning the Battery

Each time the battery is charged, its capacity decreases slightly. Therefore, the operating time the monitor can run on battery power decreases slightly with each charge cycle. Battery reconditioning recalibrates the battery to ensure that the value stored in the battery for its full capacity takes this decrease in capacity into account and allows the remaining battery charge to be calculated accurately.

Philips recommends that you condition the battery by fully discharging and recharging it every six months.

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 monitor’s 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 monitor’s Error Log. To view the Error Log, see “Viewing and Printing the Error Log” on page 6-33. For a complete list of error codes and actions to take, see Chapter 6, “Troubleshooting.”
