Cleaning and Disinfecting

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.

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

OK

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.

Caution A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor. However, if

there is independent demonstration that a particular calibration curve is accurate for the
combination of a pulse oximeter monitor and a pulse oximeter sensor, then a functional tester can
measure the contribution of a monitor to the total error of a monitor/sensor system. The functional
tester can then measure how accurately a particular pulse oximeter monitor is reproducing that

Troubleshooting

Use this information in this section to diagnose and resolve problems with the monitor.

There are two methods of repairing the monitor:

• Bench repair

• Spare parts

Before performing a repair, consider whether a replacement would be more suitable.

Special tools are required to repair the monitor. The section, “Tools Required for Service” on
page 7-1 lists these. If you open the case for a repair, you then must perform specific tests
after reassembly. Chapter 5, “Performance Verification Testing,” lists these tests in detail and
also includes recommended frequency.

The troubleshooting techniques in this chapter show how to troubleshoot a monitor that is not
operating correctly. Chapter 7, “Repairing the Monitor,” describes how to perform the
recommended repairs.

The Philips Parts Center stocks board level assemblies and mechanical parts.
Chapter 8, “Replacement Parts and Assembly Drawings,” lists these parts and assemblies.
Service notes announce the availability of additional spare parts.

When You Cannot Correct a Problem

Use the troubleshooting tables, run the diagnostics, refer to the error codes in this chapter, and
then take the recommended actions to correct the majority of problems. If you still cannot
isolate a problem after using the tables and diagnostics in this chapter, call the Philips
Customer Care Center or your local representative.

Diagnosing a Problem

Note — Before you begin to troubleshoot a problem or open the monitor ensure that the monitor has

power and a functioning display.

Check the following basics first:

1. Is the power switch turned on?

2. Is the battery adequately charged?

3. Is the power cord connected to the monitor and plugged into an AC outlet?

You can isolate many problems by observing the indicators on the monitor before you open it for repair.

Note — It may take several seconds for the AC Power LED to light/turn off after the power cord has
been connected/disconnected.

Diagnosing a Problem

If the monitor is not receiving power:

1. Check “Boot and Power Sequences” on page 6-4, and then follow the troubleshooting steps in
“Power Problems” on page 6-6.

2. If the monitor has no display or an incorrect display, follow the troubleshooting steps in “Display
Problems” on page 6-8.

Having power and an active, functioning display is critical to understanding the status of the
monitor. After the monitor has power and a functioning display, you can use the information in this
chapter to diagnose other monitor problems.
