The Walk200b device is designed to be connected to a PC. The system that consists of the Walk200b device and the non-medical PC equipment is defined as an electromedical system. The adoption of an electromedical system requires compliance with the requirements of the Directive.
The use of a medical separation transformer must be used with the electromedical system consisting of the Walk200b, a PC and any other non- medical equipment (such as printer and monitor). Consult a CARDIOLINE® Service Centre for more detailed information. Alternatively, a PC compliant with medical standard EN60601-1 can be used. A separation transformer cannot be used unless compliance with the following conditions has been confirmed with absolute certainty:
After measurements taken according to the EN60601-1 standard, the dispersion currents in the case of the PC and of any other non-medical devices that are connected (monitor, printer, etc.) are less than 0.1 mA.
The non-medical devices in the system are connected outside the patient area, that is, not within 1.5 m of the patient and/or his or her bed.
If a separation transformer is not used, install the system in such a way that the operator cannot touch the patient and the case of the any non-medical equipment outside the patient area at the same time.
If the PC and any other non-medical devices that are connected (monitor, printer, etc…) are powered by the medical separation transformer, they may be located inside the “patient area”, i.e. within 1.5 m of the patient and/or his or her bed.
The PC and any other devices to be used in the system (monitor, printer, etc.) must only be connected to the separation transformer using the cables and any other accessories supplied with the system. Extension cords, socket adapters and other types of connections may not be used unless supplied with the system.
It is categorically forbidden to connect other equipment that is not part of the system to the separation transformer or to a multiple extension cord supplied with the system.
If a non-medical device that is part of the system is connected to a non- prescribed type of socket (a wall socket, for example), the system no longer complies with medical standards and the patient may be endangered.
If a non-standard device is connected to the socket of the separation transformer specified for the system devices, this could create situations of danger for the patient, operators or environment (overloading or overheating of the sockets and separation transformer.
The separation transformer and any multiple sockets connected to it must not be placed directly on the floor or any area that may be flooded, or in which dirt may accumulate. The transformer and sockets must be placed in an area that is easy to inspect, both for regular cleaning and for the required maintenance.
The installer must install the system in the optimum way to satisfy the safety regulations and provide the greatest facility and ease of use by both the user and the patient.

5.4.2. Keys
ON/OFF This key switches the Walk200b recorder on and off. To prevent switching it on or off by mistake, the key reacts only after 2 seconds. As with all other keys blood pressure measurement can also interrupted prematurely, causing the pressure in the cuff to be released rapidity. Warning: switch the unit on again to continue.
Start You have to press the start button to begin a 24 hours measurement session, and to perform a measurement outside of measuring cycles previously indicated. Attention: The physician must verify the reliability of the values of the first measurement, so that we can continue with successive measurements correct, and the proper positioning of the cuff. In the event of an error, follow the directions in the paragraph “preparation for the measurement and search of errors”. When you press the START button, on the display appears the number of measurements recorded up to that moment, and start the manual measurement. During the first measurement the cuff will inflate gradually. Once the necessary pressure in the cuff for the measurement of the systolic blood pressure value has been determined, that value will be stored and will be reached automatically in the subsequent automatic measurements. The patient can use the START button to record an additional manual measurement outside of the recording protocol.
17

Walk200b 5. INTRODUCTION
Night and day This key allows waking and sleeping phases differentiated when recording, wich is important from the point of view of statistical evaluation and graphic presentation. Briefly: the patient is instructed to operate the DAY/NIGHT Key on going to bed and again when getting up in the morning. This adjusts the monitoring interval to suit the individual patient and helps you in assessing the BP profile. As well as adjusting the interval, the appropriate notes are shown on the printout. If this key is not operated, the change in interval will take place according to the protocol selected
Event Marker This key allows the patient to record the time at which medication in taken or any events happen that may cause blood pressure to rise or fall. Pressing this key directly triggers a measurement. The patient should note the reason for pressing the Event Key in the event diary.
5.4.3. Display
The LCD display is located on the front of the recorder housing. It displays useful information for the doctor and patient on measurement data, monitor settings and measurement errors.
5.4.4. Acoustic signals
The acoustic signals used consist of single or multiple beeps. The following signals are emitted:
1 beep: Switching on or off, start and completion of a measurement (except for night intervals), removal of interface cable, end of IR communication, set-up and end of Bluetooth communication, and measuring error
3 beep: system error Continuous beep: Serious system error (e.g. cuff pressure is greater than 15 mmHg for more than 10
seconds outside of a measurement) Combined beeps: When deleting measurements manually, first one beep is emitted and 2 seconds
later 5 beeps
5.4.5. Cuff connection
The cuff connection is fitted on the front of the recorder housing. This metal plug is used to connect the recorder with the cuff via the cuff tube and the metal cuff socket.
NOTE: Both the doctor and the patient should be aware that the metal plug (air connector) must always engage with an audible “click”. Otherwise there will be a leaky connection between recorder and the tube that will produce incorrect measurements.

6.1. Initial startup
Connect the cuff tube with one of the cuffs supplied (according to instructions in par. 6.3), by pushing it onto the plastic connector.
Connect the cuff tube with the socket on the front of the recorder housing. First check that the batteries have been inserted correctly. You should always use fully charged
batteries for a new monitoring session. Alternatively, you can use alkaline batteries. Take care to insert the batteries the right way round. NOTE: Use only the Ni-Mh rechargeable batteries with minimum capacity of 1500 mAh and maximum capacity of 2450 mAh (AA) or alkaline batteries 1,5 V ( AA). Other types of batteries with higher capacity o lithium ones MUST NOT be used. NOTE: It is recommended that the rechargeable Ni-Mh batteries be charged and discharged a few times before using them with the device..
6.2. Preparation for use
6.2.1. Switching on
Always check the condition of your recorder first, before you give it to a patient. You can do this by observing the initial displays shown on the recorder shortly after switching it on. Press the ON/OFF key and look at the following sequence of displays should appear:
Battery status (Volts): for Ni-Mh rechargeable batteries min. 2.75; for alkaline batteries min. 3.10 Display segment test: 999:999 to 000:000; Along with the numbers, all the other LCD symbols are
shown. Check whether all segments are being shown correctly and completely (the complete code is constantly being checked for correctness in the background) Current 24 hour time : Example: 12:55 If a fault occurs during the internal test, the recorder shows E004 on the display and emits an acoustic signal. For safety reasons, use of the recorder is blocked. Return the recorder to your specialist dealer or directly to Cardioline.

Walk200b 6. EXECUTION OF AN EXAM

6.2.2. Clearing memory
The memory must be cleared before each monitoring session, i.e. no blood pressure data from the previous patient must be left in the memory. However, should values still be present, you can delete them with the delete function of the analysis software. You can clear the memory manually, by holding the START key for more than 5 seconds. A number will appear in the display indicating the number of measurements present in the memory (after the prompt clr). To confirm that you want to erase the memory press and hold the event key (within 5 seconds after the prompt clr). The following prompt 000 in the display confirms that the memory has been erased.
6.2.3. Setting the time/date
The Walk200b has an internal buffer battery that allows the clock to continue running even after the batteries have been removed. You should nevertheless check the time and date before each measurement series. The time and date can be set with the CUBE analysis software. You can also set the time and date manually by holding the START key and then pressing the EVENT key. Now you are in the “Set time” mode. Use the START key to change the number in question, and use the EVENT key to jump to the next.

6.2.4. Inserting patient data (ID)
The recorder must be prepared inserting the patient data (ID), so that measurements are allocated correctly when reading out. Patient data can be transmitted to the recorder using one of the compatible Cardioline software (Cubeabpm, webuploader or Device Web Manager). Please refer to the user manual of these software for more instructions.

6.2.5. Setting the measurement protocol

The protocols can be set using the Cubeabpm software Each interval is configurable with measurements from 5, 10, 15, 20, 25, 30, 40, 50, 60, 90 and 120 minutes. By scheduling an interval of automatic measurements every 5 minutes (minimum interval) for both day and night, in 24h you will have the opportunity to make N. 288 measurements. In addition to the programmed automatic measurements, pressing the Event Marker button will allow you to start additional manual measurements to the preset duty cycle until a maximum of 300 measurements are reached in total.

You can also set the protocols manually by pressing the DAY/NIGHT button and then pressing the EVENT button. Use the START button to change protocol, and then confirm with the EVENT button.

Press the Retry key;
6.3. Putting on the recorder
Put the equipment pouch on the patient. By varying the length of the strap you can use it either as a hip belt or a shoulder strap. Alternatively, use a normal belt that matches the patient’s clothing. Now fit the cuff on the patient; correct cuff fit is extremely important for accurate measurement (see figure beloe). The cuff can also be worn over the shirt or blouse. We recommend that the cuff be fitted on the bare upper arm. In this case, bring the tube out between the buttons of the shirt or blouse, around the back of the neck to the ABP monitor on the right-hand side.
23

Walk200b 6. EXECUTION OF AN EXAM

Placing the cuff

Please note the following points:
1. When putting the recorder on the patient, the recorder must not be connected to other external equipment.
2. The cuff must fit so that the air tube cannot be kinked or compressed at any point. The tube connection on the cuff should therefore be directed upwards. The air tube should allow free movement of the upper arm and should run over the back of the neck to the other side of the body.
3. It is essential to ensure that the artery symbol lies over the brachial artery. When the cuff fits correctly, the metal strip is on the outer side of the upper arm (elbow side).
4. The material loop must cover the skin under the metal strip.
5. The lower edge of the cuff should be about 2 cm above the bend of the patient’s elbow.
6. The cuff should fit relatively snugly on the upper arm. Correct fit can be checked by a simple test: there should be room to slip one finger under the cuff.
7. The correct cuff size is also important if blood pressure is to be measured correctly.
8. To obtain reproducible results, standardised monitoring conditions are required, so the cuff must be the correct size for the patient. Using the tape measure supplied, measure the circumference at the middle of the upper arm and select the appropriate cuff:

Upper arm circumference

cuff

14-20 cm

XS

20 – 24 cm

S

24 – 32 cm

M

32 – 38 cm

L

38 – 55 cm

XL

9. Connect the air tube from the cuff to the ABP recorder.

10. Push the tube firmly over the connection until a click is heard as it engages; to disconnect, simply pull back the outer metal ring on the plug.

11. The recorder is now correctly fitted and ready for use.

24

Walk200b 6. EXECUTION OF AN EXAM
NOTE: The bag and the Walk 200b Waterproof case, mentioned in paragraph 8.2, are not intended to come into direct contact with the body. It is therefore recommended to place them over a piece of clothing (e.g. a T shirt).
6.4. Starting measurements
Once all these steps have been completed, the monitor can be started. First, a manual measurement must be carried out by pressing the START key. This measurement is used to determine whether the recorder is working correctly. If errors occur, check once more that the procedure followed in setting up and fitting the equipment was correct. Should this not solve the problem, repeat the setting-up procedure. Only after a successful manual measurement the patient can be allowed to leave with the equipment.
6.5. Interrupting measurements
During a measurement, any key can be used to interrupt the measurement. The display then shows “-STOP-” and beeps 5 times. The process is also saved in the table of measurements under “Interruption”.
6.6. Download of the recordings
At the end of the measurement the recordings can be downloaded from the recorder using one of the compatible Cardioline software (Cubeabpm, webuploader or Device Web Manager). Please refer to the user manual of these software for more instructions.
25

Walk200b 7. MAINTENANCE AND TROUBLESHOOTING
7. MAINTENANCE AND TROUBLESHOOTING
7.1. Principal sources of error
The following may cause faulty measurements or undesired results: Arm movement by the patient during the measurement Switching off the device (e.g. at night) Incorrect cuff size fitted Slipping of the cuff in use Absence of successful manual measurement at the surgery Failure to take medication Incorrect protocol set by the user Batteries not fully or correctly charged, or worn out Defect in the charging unit
In case of failed measurement, Walk200b will automatically start an additional measurement after 3 minutes from the previous failed one.
7.2. Cleaning of the recorder
Cleaning operations must be performed by medical staff. Don’t sterilize the device. To clean and disinfect the equipment surface, use a sterilizing detergent solution as generally used in hospitals, with low alcohol content. The unit surface may be cleaned with a wet tissue, but the liquid must never infiltrate the equipment. Wash the electrodes with water and/or use only cool sterilization. NOTE: remove the battery before the cleaning.
7.3. Cleaning of cuffs
Cleaning operations must be performed by medical staff. The cuffs are reusable for an unlimited period of time. Before washing, remove the air cushion. Take care not to kink the air cushion in the covering cloth after replacement. Wash the covering cloth with warm water(~30°C) using a mild washing powder (do not spin). Do not use fabric softeners or other aids (disinfectant rinses or textile deodorants), these solutions may leave residues and damage the materials. The cuff sleeve is not suitable for drying in a tumble dryer.
26

Walk200b 7. MAINTENANCE AND TROUBLESHOOTING
Wash the bladder only with warm water, adding a mild cleaning solution if necessary and wipe off. Take care to ensure that no water enters the tube opening. When using other disinfectants not recommended by IEM, the user is responsible for proving harmless application. Never use disinfectants that leave a residue on the product or which are unsuitable for use in contact with skin.
7.4. Display maintenance
Keep the display dry avoiding the formation of condensation. Failure to respect these strategies may result in the loss of liquid crystals. To clean the display surface, use a soft cloth. The use of cloths that are too rough may scratch it. Do not use solvent-based chemical products. Warning: if the display panel breaks, do not swallow the liquid that comes out. In case of contact with the skin or clothing, immediately wash them using plenty of soap and water. Abnormalities in the display of fonts may be caused by heavy pressure during use. Normal functioning will be re-established.
7.5. Periodic checks
Cuffs and tubes control when necessary and at least once a year. General check of the functionality of the instrument and of the leakage current: when necessary or at least every 2 years. Check the calibration every other year.
Check the printout carefully for: Correctly entered times and intervals in accordance with the protocol Times of day/night changeovers Correctness of standard values (nocturnal reduction) Battery voltage
7.5.1. Checking the battery voltage:
The fully charged batteries are installed in the monitor directly from the charging unit. The battery voltage is shown in the LCD display of the Walk200b monitor shortly after switching on the device, for approx. 3 sec. This voltage should be at least 2.75 V to guarantee measurement over 24 hours.
7.5.2 Calibration
The device has been calibrated by the manufacturer; a label inside the battery compartment shows the calibration’s expiry date. It is recommended to check the calibration regularly – at least once every other year. The calibration may be verified by Cardioline or by any authorised service centre.

Calibration expiry label

7.6. How to change the batteries
The batteries, 2 AA ultra alkaline or rechargeable NiMh (at least 1500mAh), should be substituted if the special indicator on the display shows a charge of less than 2,75%. Rechargeable batteries are subject to aging. In case the rechargeable batteries are damaged or is no longer possible to make measurements for the 24 hours with it, they must be replaced immediately. Ni- Mh rechargeable batteries last longer if they are discharged completely before a new recharging. Batteries run depending on the temperature. It is suggested to leave the rechargeable batteries into its charger until they need to be used.
WARNING: Before removing or inserting the batteries from the recorder ensure that the same is turned off and that the patient is disconnected.
Open the battery compartment door. Insert the batteries placing their polarities in the correct position. Close the battery compartment door.
WARNING: The insertion of batteries with incorrect polarities means that the device will not work. WARNING: do not dispose of the substituted batteries in the environment. WARNING: do not use battery types that are different from each other in terms of technology and specifications. WARNING: remove the batteries from the unit if it will be out of use for a long time. NOTE: Removal of the batteries does not mean the loss of data.

Pursuant to Italian Legislative Decree no. 49 dated 14 March 2014 “Implementation of Directive 2012/19/EU on Waste Electrical and Electronic Equipment (WEEE)”, the crossed-out “wheeled bin” symbol on the medical device indicates that, at the end of its service life, the product must be collected separately from other wastes. Therefore, when disposing of the product at the end of its service life, the user is required to contact the supplier or the manufacturer. Suitable differentiated collection to allow for the subsequent recycling of the decommissioned device, with environmentally-compatible treatment and disposal, helps to prevent any negative effects on the environment and health and to promote the recycling of the materials from which the device is made. The illegal disposal of the product by the user entails the application of administrative sanctions envisioned by Italian Legislative Decree no. 22/1997 (Art. 50 and subsequent to the Italian Legislative Decree no. 22/1997).
