1.3.3 Safety precautions Warnings WARNING

A WARNING indicates a situation in which the user or the patient may be in danger of injury or death.

Power connection •

Before connecting the power cord to the mains outlet, check that the local voltage and frequency correspond with the rating stated on the device plate on the rear panel of Central Unit, F-CU8, and the Video Display, D-VHC17. See instructions for different displays from section “Displays”.

•

Connect the monitor to a three-wire, grounded, hospital grade socket. Do not remove the grounding pin from the power plug.

•

Use only an intact power cord. Replace the power cord if it is cracked, frayed, broken or otherwise damaged.

•

Do not apply tension to the power cord otherwise the cord may get damaged.

•

Do not use extension cords or adapters of any type.

•

When using the ARK Barcode Reader, N-SCAN, do not stare into beam. The N-SCAN is a Class 2 laser product.

Laser radiation

External connection •

Do not connect any external devices to the monitor other than those specified by DatexOhmeda.

Fuse replacement •

Replace a fuse only with one of the same type and rating.

•

Do not use the monitor in the presence of flammable anesthetics.

Explosion hazard

7 Document No. 8002783

Datex-Ohmeda S/5 Anesthesia Monitor and S/5 Critical Care Monitor Patient safety •

Do not perform any testing or maintenance on the monitor while it is being used on a patient.

•

Use only cables and accessories approved by Datex-Ohmeda. Do not modify them. Other cables and accessories may damage the monitor or interfere with the measurement.

•

PACEMAKER PATIENTS: The impedance respiration measurement may cause rate changes in Minute Ventilation Rate Responsive Pacemakers. In this case set the pacemaker rate responsive mode off or turn the monitor impedance respiration measurement off.

Cleaning and service •

Only trained personnel with proper tools and test equipment should perform the tests and repairs described in this manual. Unauthorized service may void the monitor warranty.

•

Turn the power off and unplug the power cord before cleaning or service. Completely remove any moisture before reconnecting the power cord to the mains outlet.

•

Do not touch any exposed wire or conductive surface while any cover is removed and the monitor is energized. The voltages present can cause injury or death.

•

Always perform an electrical safety check and a leakage current test on the monitor after service.

Cautions CAUTION

A CAUTION indicates a condition that may lead to equipment damage or malfunction.

Installation •

Leave a space behind the monitor to allow proper ventilation.

•

Allow two minutes for warm-up and note any error messages or deviations from normal operation.

•

Clean the rear panel fan dust filter once a month or whenever necessary.

•

Do not connect a sampling line to the female Patient Spirometry connector while the other end of the sampling line is connected to the D-fend water trap. The pressure in the gas sampling system may cause damage to the PVX unit pressure transducer.

Before use

Autoclaving and sterilizing •

Do not autoclave any part of the monitor.

•

Do not gas sterilize the modules.

Cleaning and service •

8 Document No. 8002783

Do not use ammonia, phenol, or acetone based cleaners. These cleaners may damage the monitor surface.

General Service Guide •

Do not immerse the monitor in any liquid. Do not allow liquid to enter the monitor or modules.

•

Electrostatic discharge through the PC boards may damage the components. Before handling PC boards, wear a static control wrist strap. Handle all PC boards by their nonconductive edges and use anti-static containers when transporting them.

•

Do not break or bypass the patient isolation barrier when testing PC boards.

Special components •

Special components are used in these monitors which are vital to assure reliability and safety. Datex-Ohmeda assumes no responsibility for damage if replacement components not approved by Datex-Ohmeda are used.

•

A lithium battery on the CPU Board. Dispose of the faulty IC containing the battery according to local regulations.

Batteries The battery package in the power supply unit contains lead acid (Pb) which is hazardous to the environment and therefore needs to be disposed of carefully according to local regulations. To replace the batteries safely, please refer to the instructions in this manual. •

Do not short-circuit the battery terminals, this may produce a very high current, which will damage the battery.

•

Do not dispose of the battery into open flame, nor put the battery near fire, as it may explode.

•

Do not dismantle the battery. It contains electrolyte, which may damage clothing or cause injury to skin or eyes. If exposed to electrolyte, wash the injured area with plenty of clean water and contact a doctor.

See also section “Displays”. Storage and transport Do not store or transport the monitor outside the specified temperature and pressure ranges: Temperature Ambient pressure Humidity except LCD Display: except D-VSC21
