CAUTION

zIndicates a potential hazard or unsafe practice that, if not avoided, could result in minor personal injury or product/property damage.

NOTE

zProvides application tips or other useful information to ensure that you get the most from your product.

1.1.1 Dangers

There are no dangers that refer to the product in general. Specific “Danger” statements may be given in the respective sections of this manual.

1-1

1.1.2 Warnings

WARNING

zThis monitor is not applicable for prolonged and continuous SpO2 monitoring, which may increase the risks of irritation and burns at the site of the sensor.

zThis monitor is not applicable for prolonged and continuous temperature monitoring for more than 5 minutes.

zThis monitor is intended for use by qualified clinical physicians or well-trained nurses in the specified places.

zIt is your responsibility to verify the device and accessories can function safely and normally before use

zThe disposable accessories should be disposed of in accordance with the hospital regulations.

zA possible fire or explosion hazard exists when used in the presence of flammable anesthetics or other flammable or explosive substances in combination with air, oxygen-enriched environments, or nitrous oxide.

zDo not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a low level or off may result in a hazard to the patient. Remember that alarm settings should be customized according to different patient situations and always keeping the patient under close surveillance is the most reliable way for safe patient monitoring.

zOpening the monitor housing presents a risk of hazard due to electrical shock. All servicing and future upgrades to this equipment must be carried out by personnel trained and authorized by Mindray only.

zDo not touch the patient or equipment connected to the patient during defibrillation. A risk of serious injury or death is present.

zWhen using the equipment with electrosurgical units (ESU), make sure the patient is safe.

zDispose of the package material according to the applicable waste control regulations and keep it out of children’s reach.

zThe device must be connected to a properly installed power outlet with protective earth contacts only. If the installation does not provide for a protective earth conductor, disconnect the monitor from the power line and operate it on battery power, if possible.

1-2

1.1.3 Cautions

CAUTION

zTo ensure patient safety, use only parts and accessories specified in this manual.

zRemove the battery from the monitor if it will not be used or not be connected to the power line for a long period.

zCarefully route patient cabling to reduce the possibility of patient entanglement or strangulation.

zDisposable devices are intended for single use only. They should not be reused as performance could degrade or contamination could occur.

zAt the end of its service life, the product described in this manual, as well as its accessories, must be disposed of in compliance with the guidelines regulating the disposal of such products. If you have any questions concerning disposal of the products, please contact with us.

zMagnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason make sure that all external devices operated in the vicinity of the monitor comply with the relevant EMC requirements. Mobile phone, X-ray equipment or MRI devices are a possible source of interference as they may emit higher levels of electromagnetic radiation.

zBefore connecting this monitor to the power line, check that the voltage and frequency ratings of the power line are the same as those indicated on the label or in this manual.

zInstall or carry the monitor properly to avoid damages caused by drop, impact, strong vibration or other mechanical force.

zIf you spill liquid on the equipment or accessories, contact us or your service personnel.

The battery is charged automatically when the monitor is connected to AC mains till it is full. If the power supply is lost during monitoring, the monitor can run on internal battery.

The battery indicator indicates the status of the battery.

ON: The battery is being charged or the battery is fully charged.

OFF: The battery is removed from the monitor, or the monitor is equipped with battery but is not connected to AC mains and not turned on.

Flashes: The monitor is powered by the internal battery.

The capacity of the internal battery is limited. When the battery capacity is too low, a high level alarm is triggered and the “Battery too low” message is given in the technical alarms area. At this moment, the AC mains shall be applied to the monitor; otherwise the monitor will power off automatically before the battery is depleted.

For details about installation of the battery, refer to 3.1.5 Installation Method:Installing the battery.

WARNING

zKeep the battery out of the reach of children.

zUse only the battery specified by the manufacturer.

NOTE

zRemove the battery before transport, or if the monitor is not likely to be used for an extended period of time.

2.4.1 Battery Maintenance

2.4.1.1 Conditioning a Battery

A battery needs at least two conditioning cycles when it is used for the first time. A battery conditioning cycle is one uninterrupted charge of the battery, followed by an uninterrupted discharge of the battery. Batteries should be conditioned regularly to maintain their useful life. Condition a battery once when it is used or stored for two months, or when its run time becomes noticeably shorter.

To condition a battery, follow this procedure:

1.Disconnect the monitor from the patient and stop all monitoring or measuring.

2.Insert the battery in need of conditioning in the battery compartment of the monitor.

3.Apply AC power to the monitor and allow the battery to charge uninterruptedly for 10 hours.

4.Remove AC power and allow the monitor to run on the battery until it shuts off.

5.Apply AC power again to the monitor and allow the battery to charge uninterruptedly for 10 hours.

This battery is now conditioned and the monitor can be returned to service.

2.4.1.2 Checking a Battery

The performance of a rechargeable battery may deteriorate over time. To check the performance of a battery, follow this procedure:

1.Disconnect the monitor from the patient and stop all monitoring or measuring.

2.Apply AC power to the monitor and allow the battery to charge uninterruptedly for 10 hours.

3.Remove AC power and allow the monitor to run on the battery until it shuts off.

4.The operating time of battery reflects its performance directly.

If the oprating time of the battery is noticeable shorter than that stated in the specifications, replace it or contact your service personnel,

NOTE

zLife expectancy of a battery depends on how frequent and how long it is used. For a properly maintained and stored lead-acid or lithium ion battery, its life expectancy is about 2 or 3 years respectively. For more aggressive use models, life expectancy can be less. We recommend replacing lead acid batteries every 2 years and lithium ion batteries every 3 years.

zThe operating time depends on the configuration and operation. For example, measuring NIBP more frequently will also shorten the operating time.

2.4.2Battery Recycling

When a battery has visual signs of damage, or no longer holds a charge, it should be replaced. Remove the old battery from the monitor and recycle it properly. To dispose of the batteries, follow local laws for proper disposal.

WARNING

zDo not disassemble batteries, or dispose of them in fire, or cause them to short circuit. They may ignite, explode, leak or heat up, causing personal injury.
