Introduction

Your new Microlife Monitor is a high-quality medical device that measures your maximum possible exhalation which is called «peak flow» (referred to in medical terms as PEF – Peak Expiratory Flow).
Regular monitoring of your peak flow is extremely useful for controlling diseases of the airways such as asthma or chronic bronchitis. After the peak flow result is shown, a further value (for FEV1) will then be indicated. This value is also of interest to your doctor. The measurements can be performed on your own, because the Microlife Monitor is very simple to use. It is as suitable for children in the pre-school age as for the elderly.
Because the device has an automatic memory of 240 data entries, you do not need to note the values down; simply take the device with you the next time you visit your doctor. The device can be connected to a computer, and the values can be analyzed by using the Microlife Asthma analyser software program. Alternatively, the values can be printed out with the small Microlife Diagnostic Printer (optional accessory).
Read through this instruction manual carefully before using the device and then keep it in a safe place.

Preparation for your first Measurement

Before your first use we recommend that you disinfect the mouthpiece as explained in this manual.

Inserting the Batteries

1. Please open the Battery Compartment from underneath and insert the two batteries (1.5 V, size AAA).
2. Please watch the polarity as indicated by the symbols in the compartment.

Setting Date and Time

The monitor automatically records the time and date of each measurement. After new batteries have been inserted, the time/date display shows the following setting: year: 2002; day 01, month 01 and time 00:00 o’clock.
You must then re-enter the date and current time. To do this, proceed as follows (Example: Entering 15th June 2002, 09:50 o’clock):

1. Please open the Data Compartment from underneath at the position of the data symbol indication.

2. Press the small-time switch next to the clock symbol with a pen and «2002» starts blinking; release the switch.

3. Using the two arrow keys on the front of the monitor you can decrease (left arrow button) or increase (right arrow button) the number. Release the arrow button when the correct number is reached.

4.  Press the time switch again to confirm the year setting and move to the month setting. The month digits blink.

5. The current month can now be entered by pressing the arrow button. (Example: pressing 5 times the right arrow button advances to 06 for June)

6. Press the time switch again to confirm the month setting and move to the day setting. The day digits blink.

7. The current day can now be entered by pressing the arrow button. (Example: pressing 14 times the right arrow button advances to 15 for 15th June)

8. Press the time switch again to confirm the day setting and move to the hour setting. The hour digits blink.

9. The current hour can now be entered by the arrow button. (Example: pressing 9 times the right arrow button moves to 09 for 09 o’clock) 10. Press the time switch again to confirm the hour setting and move to the minute setting.
   The minute digits will now blink.

10. The current minutes can now be entered by pressing the arrow button. (Example: pressing 9 times on the left arrow button moves to 50 for 09:50 o’clock).

11. Press the time switch again to confirm all settings. Date and time are now stored, the clock starts running and the monitor switches to «ready» state condition which enables your first measurement.

12. Close the data compartment.

Please note:

• If you hold down the arrow key for more than 2 seconds it speeds up.
• Date /time can also be set easily from the computer when you run the Microlife Asthma Analyser Software.

Carrying out a Measurement

• When different people use this meter their individual readings cannot be assigned to different users when the data is stored.
• If time/date is not set, measurements can not be performed.
• If another person intends to use the device permanently, all data from the previous user should be erased as explained in this manual.
• In case another user has already used the monitor, we recommend disinfecting the measuring tube as explained in this manual.  In this case we also recommend that each user uses a new mouthpiece. Extra mouthpieces can be ordered through your Microlife dealer.

1. Press the ON/OFF button to turn the monitor on. At first, the last result of the memory is shown («0» if there are not yet data) and then the device indicates «READY» for measurement by two short beeps and blinking arrows.
2. You can perform the measurement while standing or sitting upright. For a better comparison of your data, you should always perform the measurement in a similar position.
3. Hold the monitor with both hands on the two rubber areas (compartments).
4. Inhale completely and hold your breath for a moment.
5. Cover the mouthpiece tightly with your lips.
6. Blow into the measuring tube as hard and as fast as you can.
7. A long beep confirms that the result is recorded. The peak flow value is displayed for about 3 seconds, then the FEV1 is shown. Afterward, the monitor is ready for a new measurement which is indicated by two short beeps.
8. It is recommended to perform three or more measurements sequentially. Please note that the monitor only saves the highest reading from switching the device on until switching it off.
9. After each measurement, at first, the actual reading is shown in the display and then it switches automatically to the highest reading of your current measurement session.
10. Press the ON/OFF button to switch the monitor off. Before the monitor switches off, the highest value and its related memory position «MR xx» is displayed.
11. Store the monitor in a clean and dust-free place.

Traffic light indicator on the device
After the measurement, a small arrow in the display will indicate if the reading is in the green, yellow or red range.
500 l/min is defined as the reference value.
If the reading is above 80% (> 400 l/min) of the reference value, it will be indicated in the green range. Reading in the yellow range indicates a reading between 60% and 80% (300 l/min – 400 l/min) of the reference value. Reading in the red range indicates a reading below 60% (< 300 l/min) of the reference value.
It would be best to determine the area limits together with your physician and when required these ranges can be set manually within the software.

Important Information for Measurement and Control of your Peak Flow

Values

• It is necessary to keep regular control of your peak flow values. Doctors generally recommend taking one measurement in the morning and one in the evening, every day, normally before inhaling your prescribed medication. Carry out additional measurements whenever you feel unwell or perceive shortness of breath.

•  Your doctor is only interested in the highest peak flow value that you can achieve during a measurement session. Please repeat the measurements until you feel you have got the best possible result for the moment. Take care to have sufficient relaxation between measurements. In case of poorer results at each successive measurement, session talk to your doctor. It may be a sign of unstable asthma.

• Please note that asthma attacks are indicated in advance by low peak flow values before you feel it! Please contact your doctor in cases such as these. Also do so if you have signs and symptoms such as chest tightness, shortness of breath coughing or wheezing.

• Self-measurement means control, not diagnosis or treatment. In any event, please be sure to discuss your measured values with your doctor. Your doctor will also explain which values are normal for you.

• You should never alter the dosages of any medication without talking to your doctor.

• Please note that the device stores up to 240 measured values with date and time.
  When the memory is full, the oldest values are automatically erased! Make sure you visit your doctor in time to analyze your data.

• Please confirm that date and time settings are always actual.

• The performance of the monitor can be affected by extremes of temperature and humidity. Please refer to «technical specifications» for details.

Self-Assessment with the Traffic Light Scheme

The so-called «traffic light scheme» allows you to self-assess your measured values and the course of your illness. This leads to an independent assessment of your illness symptoms with adjustment of your medication. If you or your physician wish to make use of this scheme, an asthma control card is enclosed with the device, on which a green, a yellow, and a red area are marked. The area limits should best be determined together with your physician and entered into the card.

Significance of the Traffic Light Scheme
Green area – OK
The lung disease is well under control. Higher medication dosage is not required.
Yellow area – Caution
Should your measured values frequently be located in this area, increase your medication dosage as discussed with your physician.
Red area – Danger
It is dangerous if your measured values are in this area! Act as discussed with your physician or seek emergency medical treatment.

Cleaning and Disinfecting

Cleaning / Disinfecting the Mouthpiece

We recommend disinfecting the mouthpiece  before your first use and at least once a week using the following procedure:

1. Disconnect the mouthpiece from the measuring tube and put it for at least 10 minutes into continuously boiling water.
2. Afterward, put the mouthpiece on a fresh paper towel and let it air dry.
3. Reassemble the mouthpiece on the measuring tube.
   • Alternatively, you can disinfect the mouthpiece by putting it into commonly available disinfecting solutions. Please carefully follow the instructions for the disinfecting solution! Make sure that it is suitable for a mouthpiece.

Cleaning / Disinfecting the Measuring Tube

• The performance of the monitor can be affected by spitting or coughing into the measuring tube. In this case please rinse the tube with distilled water (available at a pharmacy or drugstore). Please do not use tap water.

1. Disconnect the measuring tube from the main unit by moving it in a forward direction.
2. Disconnect the mouthpiece from the measuring tube.
3.  Rinse the tube in distilled water, afterward please shake off the water and put it on a fresh paper towel for complete drying.

• In case another user has already used the monitor the measuring tube should be disinfected:

1.  Disconnect the tube as explained above and put it into a commonly available disinfecting solution. Please carefully follow the instructions for the disinfecting solution!
2. Never put the measuring tube into boiling water!
3. Reconnect the mouthpiece to the measuring tube and reassemble it back to the main unit as shown. Make sure that the tube finally «clicks» into the fixed position.
4. Please make sure that the measurement tube and the device stay together by confirming that the identification on the tube and device is the same.

Cleaning the Main Unit

Clean the main unit once a day with a clean, damp cloth. Never put the main unit into water!

Memory Handling

The 240 measuring data can be reviewed on the display:

1. Switch the monitor on and press the memory scroll buttons.
2. By pressing the «<» button, you can see the latest value stored in the memory with date and time; pressing this button once at a time shows all stored data. If you keep pressing the button you can move quickly through the memory.
3. The «>» button works in the opposite direction.

• Memory Capacity Low
  When the memory covers 230 or more data, «MR XX» is blinking after the monitor is switched on to indicate that the remaining memory capacity is low.

• Memory Full
  When the memory is full with 240 data, the monitor gives a warning «beep» when switching on and «MR 240» is blinking. From now on, data is still memorized but the oldest values are automatically erased!

• Memory Clear
  Please note: the memory is automatically cleared after data transfer to the computer.
  Clearing all data from the memory manually should be done when you intend to give the monitor to another person. To clear all data press the «<» and the «>» buttons simultaneously for 5 seconds, and then release the buttons. «clr» starts blinking in the display for about 3 seconds. If you really want to erase all data from memory you need to press the ON/OFF button during these seconds. Otherwise, the monitor moves back to normal operation and the data remains.

• Clear the last measurement
  You can erase the last memory reading by pressing both memory scroll buttons simultaneously for 5 seconds. After releasing the buttons «clr» will flash on the screen for 3 seconds. To erase the last reading you need to press both buttons again while the screen is flashing.
