WARNING! Make sure that the cable does not get caught in moving parts. WARNING! > Only use original spare parts for repairs. > Only repair bed when it is in lowest position. > Pull out power plug before repair or cleaning.

2.5. Electromagnetic/-static interference To ensure protection against electromagnetic and electrostatic interference (EMV), the S 960-2 hospital bed fulfils all the requirements of the relevant sections of the German medical products law (MPG). As this bed is not fitted with a control unit with a frequency in excess of 9kHz and in use is mainly motor-driven over short periods, it conforms to EN 55014-1, as foreseen in EN 60601-1-2 36.201.1.4.

2.6. Before using the bed for the first time Before the bed is put into service for the first time, this user’s manual must be closely read by all those responsible for nursing care. Before the bed is put into service for the first time, it is absolutely essential to carry out a functional test. Before first use, carers must receive detailed instructions in the operation of the bed. In addition, carers must be made fully aware of potential dangers that can arise in spite of the correct operation of the bed.

2.7. Checking the operational safety and condition of the bed Before putting the bed into service, it is essential to make absolutely sure that it is in good working condition and safe to use. This test must not only be carried out before first use, but continuously throughout the service life of the bed. If necessary, the bed must be tested daily or after each shift to ensure that its use does not endanger anybody. To reduce maintenance to a necessary minimum, the bed should be cleaned, disinfected and tested as soon as possible after each use so that it can be used again without delay or risk. In cases of malfunctioning, it may be necessary to transfer the patient to another bed.

2.8. Position of the hospital bed – Danger if falling out of bed In the case of unsupervised patients, we recommend that the bed is put into its lowest position to minimise the risk of injury due to falling out of bed. In other cases, should be put at a height proportionate to the size of the patient.

2.9. Four-castor central braking system – Caution! Risk of accident Unless in transport, the brakes must always be applied so that patients can use the bed as a support when accessing or exiting it. Serious falls can result through an unbraked bed rolling away. After applying the brakes, check that the bed is really immobile, ie that the brakes are fully applied to all four castors.

2.10. Height adjustment – Risk of entrapment between bed-frame and chassis When adjusting the bed, make absolutely sure that no limbs, bedding or other objects are situated between the

2.11. Safety frames - Danger of entrapment In the case of patients whose physical or mental state may be felt to call for the use of safety frames to protect them from falling out of bed, the following safety measures must be observed at all times: 1.

Safety frames may be operated only by carers instructed in their use.

2. Make sure safety frames – or elements of them – are either fully raised and locked or fully lowered. 3. During the electrical adjustment of the mattress-frame, make sure that the patient is not touching the safety frames. Also make absolutely sure that no limbs are poking through the frames.

4. If the safety frames are being used to protect a child or a person whose physical state may make their use appropriate, then make sure that the handset is out of reach. We also recommend the use of safety frame covers. Failure by carers to obey these safety rules may cause hæmatoma or other injury to hands, knees, fingers, feet, shins and hips through entrapment.

2.12. Cleaning and disinfection Risks can arise through the incorrect cleaning and/or disinfection of the bed.

2.13. Service and maintenance The S 960-2 bed requires very little maintenance. All moving parts of the lifting gear, mattress-frame drives and safety frames are permanently lubricated during manufacture. None of these parts need relubrication when the bed is correctly used and cleaned. The manufacturer assumes, however, that beds are regularly inspected and damage such as worn parts, loose screws or fractures are immediately put right.

4. Operational units General operating instructions 4.1.1. Safety class The bed conforms to Safety Class II. The bed is fitted with a connection for a voltage compensator. The bed is supplied with electricity via the power cable. It is isolated from the mains circuit by a cut-out when it is not in use.

4.1.2. Operating interval The maximum operating interval of the electrically-powered bed functions is given on the bed (name plate) and/or in the technical data sheet as “1 min / 10 min”, ie each bed function may only be continuously operated for a maximum of 1 minute in any 10 minutes. Automatic safety devices kick in if the maximum operating interval of 1 minute is repeatedly or markedly exceeded, leading to the power drives cutting out. The bed must then be inspected and tested! An integrated time-lag device hinders the accidental or brief operation of the keyboard and consequent movement of the mattress-frame. This device requires that users consciously press and hold down the relevant key. Functions then kick in after a time-lag of ca. 0.5 seconds.

4.1.3. Built-in safety cut-out The bed is fitted with a built-in electronic safety cut-out that hinders the overloading of the drives. In the event of overloading, the drives are automatically switched off. 4.2. Putting bed into service for the first time

Location The bed is authorised for use solely in dry rooms, not in wet rooms such as bathrooms. A mains power supply socket and, if required, a voltage compensator connection must be available in the room in which the bed is to be used. The bed is mobile without the need for auxiliary transport equipment. The bed may only be moved on firm surfaces. Moving the bed over obstacles greater than 2 cm in height is prohibited. Gradiants may not exceed an angle of 10°. The bed is supplied complete and can be set up without first having to remove transport equipment.

On change of shift, carers responsible for operating the bed must always check whether it is deactivated.

Automatic mode: JACK The automatic lifting function raises or lowers the bed after “double clicking” the key marked with a 3 on the carers’ keyboard/control box. This function can be interrupted by “single clicking” any key on the carers’ keyboard/control box or the handset. 4.2.3. Charge level display, battery pack The S 960-2 is optionally equipped with a rechargeable battery for the operation of emergency functions during power cuts. When undamaged and fully charged, the battery can carry out 4 complete height adjustment cycles (fully raised and fully lowered) and a further 5 mattress-frame adjustments. If height adjustment is not required, then 30 complete mattress-frame adjustment cycles are possible. The battery charge level is shown by means of the diodes (LEDs), as follows: - Green: The battery is connected to the mains supply, current is flowing through the mains cut-out and the bed is live. - Orange: Charging is in progress. - Rot: The battery must be charged or it could become completely exhausted. In this case, there is also an acoustic signal when the bed is not connected to the mains supply. When the battery is fully charged, all diodes go out. The mains cut-out then kicks in and the bed is disconnected from the mains supply. If the battery reacts, the charging cycle begins each time the bed is connected to the mains supply. Furthermore, the battery charge level is checked hourly and if it is found to be below a certain value, current flows through the mains cut-out and the battery recharges. It is essential to pull out the mains plug before transporting the bed! If the bed is put into storage with disconnected charger, then self-discharge through leakage leads to the exhaustion of the batteries! Totally discharged batteries can be so badly damaged as to necessitate their premature replacement! In order to achieve a long service life, the correct treatment of both the batteries and the charger is absolutely essential!
