 Intended Use

What it is:

The CLEVER CHEK TD-3250 system is a 2 in 1 system designed to measure blood glucose outside of human body and to measure blood pressure non-invasively. The system performs only one function at a time to avoid any interference problems. The system consists of the CLEVER CHEK TD-3250 monitor, test strips, and check & code strip. The system also comes with control solutions for quality control.

How it works:

Blood glucose is tested using an Amperometric Biosensor. Capillary action at the absorbent hole of the test strip draws a small amount of blood into the reaction chamber, and then the reading is displayed after 10 seconds.

Blood pressure is measured non-invasively at the upper arm based on the oscillometric method.

 Health Information

Blood Glucose

Blood glucose monitoring plays an important role in diabetes control. A long-term study shows that keeping blood glucose levels close to normal can reduce the risk of diabetes complications by up to 60 %.*

The results you get with the CLEVER CHEK TD-3250 can help you and your healthcare professional monitor and adjust your treatment plan to gain better control of your diabetes. The American Diabetes Association (ADA) recommends that you keep your blood sugar levels at:

Time of day ADA recommendation

Before

meals

80-120 mg/dL / 4.5-6.7

mmol/L

1-2 hours

after meals

Less than 180 mg/dL /

BEFORE YOU ST ART

Blood Pressure

Clinical studies show that the adult diabetes is often accompanied by elevated blood pressure. People with diabetes can reduce their heart risk by managing their blood pressure along with diabetes treatment*. Knowing your routine blood pressure trend tells whether your body is in good condition or not. Human blood pressure naturally increases after reaching middle age. This symptom is a result of continuous aging of the blood vessel. Further causes include obesity, lack of exercise, and cholesterol (LDL) adhering to the blood vessels. Rising of blood pressure accelerates hardening of the arteries, and the body becomes more susceptible to apoplexy and coronary infarction. The WHO (world health organization) published the guideline of blood pressure range:

ABOUT THIS SYSTEM

 Test Strip Description

Your system measures the amount of sugar (glucose) in whole blood. Blood is applied to the absorbent hole of the test strip and is automatically drawn into the reaction chamber where the reaction takes place.

The test strip consists of the following parts:

ABOUT THIS SYSTEM

Important usage information

When you get a new vial of test strips:

 Check the expiry date on the vial. Do not use test strips beyond the expiry

date since they may cause inaccurate results.

 Write the discard date on the vial when you first open it.

When you use a test strip:

 Touch the test strip with clean and dry hands.  Tightly close the vial cap immediately after removing a test strip.  Use each test strip immediately after removing it from the vial.  Do not bend, cut or alter a test strip in any way.  Apply only blood sample to the absorbent hole. Applying other substances to

the absorbent hole will cause inaccurate results.

When you store your test strips:

 Store your test strips in their original vial only; do not transfer them to a new

bottle or any other container.

 Store test strip packages in a cool and dry place between 4

C (39oF) and

C (104oF). Keep away from direct sunlight and heat.

 Discard remaining test strips and the vial three months after first opening

date.

Warning! Keep the test strip vial away from children. The cap is a choking hazard. The vial contains a pouch filled with drying agents that may be harmful if inhaled or swallowed and may cause skin or eye irritation.

(Fig. 1)

(Fig. 2)

 Battery Installation and Replacement

Your monitor comes with batteries already installed. When replacing, use ONLY 1.5V AA size alkaline batteries for best performance and longest life.

Low Power Signal

The monitor will remind you when the power is getting low by displaying two different messages:

1. Battery Symbol

appears while you perform tests. (Fig. 1) This means it is about time to change the batteries although still 30 more measurements can be made.

2. Battery Symbol flashes by itself and the monitor cannot perform any measurement. (Fig. 2) This means you must change the batteries before making any measurements.

PREPARATIONS BEFORE USE

Battery Replacement

To replace the batteries, make sure the monitor is turned off.

Step1- Press the edge of the battery cover and pull up. (Fig. 3) Lift the battery cover and remove the batteries inside.

HOW TO MEASURE BLOOD GLUCOSE

 Important Information and Possible Interferences

Important Information:

 Test results below 3.3mmol/L (60mg/dL) indicate hypoglycemia, which

means abnormally low glucose level. If higher than 13.3mmol/L (240 mg/dL), symptoms of hyperglycemia might occur. Consult your physician when a result above occurs.

 If you have symptoms that are not consistent with your blood glucose or

pressure level AND you have followed all instructions described in the user’s manual, contact your healthcare professional.

Possible interferences:

 Severe dehydration and excessive water loss may cause false low results.  A red blood cell percentage (hematocrit) that is extremely high (above 60%)

or low (less than 20%) may cause false results.

 Elevated blood triglyceride, reducing substances such as uric acid and

ascorbic acid at normal blood concentration, or acetaminophen, dopa, methyldopa, L-dopa, and tolbutamide at normal blood concentrations do not significantly affect the test results.

HOW TO MEASURE BLOOD GLUCOSE

 Coding the Monitor

You must code the monitor every time you begin to use a new vial of test strips. Test results may be inaccurate if the code number displayed on the monitor

does not match the number printed on the strip vial.

Step 1- Insert the check & code strip when the monitor is off. Wait until the code number appears on the LCD display. (Fig 8)

Make sure the code number on LCD display, on check & code strip, and on strip vial are the same.

Step 2- Remove the check & code strip, the LCD display will show “OK”. This tells you that the monitor has finished coding and is ready for blood glucose testing.

(Fig. 8)

HOW TO MEASURE BLOOD GLUCOSE

 Checking the Code

When you start measuring blood glucose, check the code number first.

Step1- With the monitor off, insert a test strip into the Test Slot. Make sure you

insert the end with the contact bars first and facing up. Contact bars must be inserted all the way into the monitor for an accurate result. (Fig. 9)

Step2- The monitor will display “CHK” and the strip symbol. (Fig. 10) In about 1 second, the ambient temperature will be shown (Fig. 11).

Step3- Then the code number and flashing blood drop appears. Check if the number shown on the monitor matches the number on the test strip vial. (Fig. 12) If it matches, you can proceed with your test.

If it does not match, please code the monitor as described in previous page.

(Fig. 10) (Fig. 11)

(Fig.12)

(Fig. 9)

HOW TO MEASURE BLOOD GLUCOSE

 Testing with Control Solution

What is a control solution test? The control solution contains a known amount of glucose that reacts with test strips. Compare your control solution test results with the expected range printed on the test strip vial label. This enables you to check if the monitor and the test strips are working together properly, and that you are performing the test correctly.

Therefore, before testing your blood glucose for the first time, practice the procedure using control solution. When you can do three tests in a row that are within the expected range, you are ready to test your blood sugar.

Please note that the control solution range printed on the test strip vial is for TaiDoc Control Solution only. It is used to test the monitor and test strip performance. It is not a recommended range for your blood glucose level.

When should I do a control solution test?

 When you begin using a new vial of test strips.  If you drop the monitor.  When your blood glucose test results are not consistent with how you feel, or

when you think your results are not accurate.

Important usage information

 Use only TaiDoc Control Solution to check system performance.  Tightly close the control solution and store below 30

C (86oF).

 Control solution, monitor, and test strips should be at room temperature

(20-25

C /68-77 oF) before testing.

 Use a period of 30 days from the date that you first open it.

Also check the expiration date on the control solution vial. Do not use if expired.

 Do not directly apply solution to the test strip. Place a drop

of control solution on a clean surface or on your fingertip instead to avoid contamination.

HOW TO MEASURE BLOOD GLUCOSE

How to do a control solution test?

Step 1- Insert a test strip and check if the code number shown on LCD display is the same as the code on the strip bottle.

Step 2- Press the M Button. The symbol "CtL" will appear on the display. When you do this, control solution readings will not be stored in the memory.

Step 3- Get a drop of control solution:

1. Shake the control solution vial well.

2. Remove the cap. Squeeze the vial and discard the first drop with a clean tissue to ensure an accurate result.

3. Squeeze the vial again to get a hanging drop and place the drop on your fingertip. (Fig.13)

Step 4- Apply the drop to the absorbent hole of the test strip until the drop is drawn into the test strip, and the confirmation window is filled. (Fig. 14)

Step 5- The monitor will begin countdown. After 10 seconds, the control solution test result will appear. The result should fall within the range printed on the test strip vial.

(Fig. 13)

(Fig. 14)

What to do if out-of-range results appear? If test results fall outside the range printed on the test strip vial, repeat the test. Out-of-range results may be caused by one or more of the following:

 Error in performing the test.  Not shaking the control solution vial vigorously.  Control solution too warm or too cold.  Expired or contaminated control solution.  Improper coding of the monitor.  Test strip deterioration.  Monitor malfunction.

If you continue to get out-of-range results, the system may not be working properly. Do not use the monitor to test your blood glucose in this condition. Please contact your local customer service for help.

 Getting a Drop of Blood

Be sure to read this section and the test strip package insert found in the test strip box carefully before testing. Make sure you have all items needed to test: monitor, test strips, lancing device, and sterile lancet.

Step 1- Insert a lancet in the adjustable lancing device.

(Fig. 15)

 Twist and remove the cap of lancing device.  Insert a lancet into the lancet holder and push down firmly

until it is fully seated. (Fig. 15)

(Fig. 16)

 Twist the protective disk until it separates from the lancet. (Fig. 16)  Replace the lancing device cap until it is snug but not too tight.

Step 2- Select the depth of puncture.

(Fig. 17)

 Twist the adjustable tip in either direction to select the depth of puncture. (Fig. 17) Five levels of depth were offered: 1-2 for soft or thin skin, 3 for average skin, and 4-5 for thick or calloused skin. Please select the most suitable depth for you to avoid unnecessary pain.

Step 3- Set the ejection control.

 Slide the ejection/cocking control back until it clicks. (Fig.

18) If it does not click, the lancing device may have been cocked when the lancet was inserted.

(Fig. 18)

(Fig. 20)

Step 4- Wash your hands. Use warm and soapy water to wash your hands. Rinse and dry thoroughly. Clean the puncture site with 70% alcohol cotton and leave it dry completely.

Step 5- Select a puncture site on fingertip.

Hold the lancing device firmly against the side of your finger. (Fig. 19) Press the release button. You will hear a click, indicating that puncture is complete.

Step 6- Obtain the required blood sample (1.8 microlitre in volume).

Gently massage the chosen area to get enough blood. Do not smear the blood sample. (Fig. 20) Proceed with your Blood glucose test.

Step 7- Discard the lancet.

Always use caution when removing the lancet.

 Remove the cap of lancing device.  Place the protective disk on a hard surface and push the

exposed tip into the protective disk.

 Take it out carefully and place it into a container for sharp objects.

WARNING!

1. To reduce the chance of infection:

 Never share a lancet with anyone.  Always use a new, sterile lancet. Lancets are for single use only.  Avoid getting lotion, oil, dirt, or debris in or on the lancets and the sampler.

2. Choose a different spot each time you test. Repeated puncture in the same spot may cause soreness and calluses. 28

(Fig. 19)

(Fig. 21)

(Fig. 22)

(Fig. 23)

 Taking a Reading

Step 1- Insert a test strip and check if the code number shown on LCD display is the same as the code on the strip vial. If not, please refer to “Coding the monitor”.

Step 2- Obtain a drop of blood as described in “Getting a Drop of Blood”.

Step 3- When the “ “ symbol is flashing on the LCD display, apply the drop of blood to the absorbent hole of the test strip. (Fig. 21) Do not push your finger against the test strip or try to apply a smeared sample.

Step 4- Make sure the blood sample completely cover the confirmation window before moving your finger away from the strip. (Fig 22) If the confirmation window is not filled completely, do

not add more blood to the test strip. Discard the test strip and retest.

Step 5- Read result after 10 seconds. (Fig 23) The test result will be automatically stored in the monitor memory. Turn the monitor off by removing the test strip.

HOW TO MEASURE BLOOD GLUCOSE

Ketone Warning: When your test reading is ≧240 mg/dL(13.3 mmol/dL), “KETONE" will appear on the LCD display.

Ketone is a byproduct produced as the body burns fat for energy when there isn't enough insulin present for the metabolism of glucose. Ketone accumulation in the blood may lead to a dangerous condition known as diabetic ketoacidosis (DKA).

High blood glucose is a symptom of insufficient insulin for people with type 1 diabetes. If you are type 1 diabetes, please beware of high ketone when your blood glucose is too high.

When "KETONE" appears, please test again. If continually appears, please consult your physician.

CAUTION!

1. If you do not apply blood sample within 3 minutes, or if you accidentally turn off the monitor by pressing the

button, the monitor will alert you with flashing test strip symbol and continuous beeping. You will need to turn the monitor off by removing the test strip.

2. To start a blood pressure test after performing a blood glucose test, make sure that the test strip is removed from the monitor. Then turn the monitor off and refer to "MEASURE BLOOD PRESSURE".

 Comparing With Laboratory Results

Results obtained from your monitor may differ somewhat from your laboratory result due to normal variation. Monitor results can be affected by factors and conditions that do not affect laboratory results in the same way.

Blood glucose levels can change significantly over short periods, especially if you have recently exercised, eaten, taken medication, or experienced stress. The glucose level of blood from fingertip would be higher than blood from a vein (venous sample) used in lab tests if you have eaten recently. The difference can be as high as 3.9 mmol/L (70 mg/dL). Therefore, it is best to fast for eight hours before doing comparison tests.

Before you go to the lab:

 Perform a control solution test to make sure that the monitor is working

properly.

 It is best to fast for eight hours before comparison test. Take your monitor

with you to the lab.

While at the lab:

 Make sure that the samples for both tests (the monitor test and the lab test)

are taken and tested within 15 minutes of each other.

 Wash your hands before obtaining a blood sample.  For the monitor test, use fresh blood from the fingertip only.  Never use your monitor with blood that has been collected in a gray-cap test

tube.

 Factors such as irregular amount of red blood cells in the blood (a high or low

hematocrit) or loss of body fluid (severe dehydration) may also cause differences between the monitor result and the laboratory result.

HOW TO MEASURE BLOOD PRESSURE

 Suggestions before Measuring

 Avoid caffeine, tea, alcohol, and cigarette at least 30 minutes before

measurement.

 Wait 30 minutes after exercising or bathing before measurement.

 Sit or lie down for at least 10 minutes before measuring.

 Do not measure when feeling anxious or tense.

 Take a 5-10 minute break between measurements. This break can be

longer if necessary, depending on your physical conditions

 Keep the records for your physician as reference.

 Blood pressure varies from two hands naturally. Always measure your

blood pressure on the same arm.

HOW TO MEASURE BLOOD PRESSURE

 Applying the Pressure Cuff

Step 1- Connect the air plug of the tubing to the air jack at the side of the monitor. (Fig.24)

Step 2- Assemble the cuff as Figure 25. The smooth cloth is on the inside of the cuff loop and the metal D-ring will not touch your skin.

Step 3- Hold your left arm in front of you with your palm facing up. Slide the cuff onto your left arm, above your elbow. The red line on the edge of the cuff should be approximately 0.8 to 1.2 inch (2 cm to 3 cm) above your elbow. Align the tubing over the main arteries at the inside of your arm. (Fig. 26)

Step 4- When the cuff is positioned correctly, pull the end of the cuff to tighten the cuff snugly around your upper arm. You should be able to fit your index finger between the cuff and your arm.

Step 5- Press the hook material firmly against the pile material. The top and bottom edges of the cuff should be tightened evenly around your upper arm.

(Fig. 24)

(Fig. 25)

(Fig. 26)

HOW TO MEASURE BLOOD PRESSURE

 Proper Measurement Position

Please sit and take a rest at least 10 minutes before measuring.

Step1- Place your elbow on a table or other object. Relax your hand with the palm facing up. (Fig 27)

Step2- Relax and make sure the cuff is at the same height as your heart. Press the button. Remain still and do not talk or move during the measurement.

(Fig. 27)

WARINING! It is extremely important that the cuff is at the same level of the heart. If the cuff is relatively lower (higher) than the heart, the blood pressure measured will be higher (lower) than the actual value. A 15cm difference in height may result in an error of 10 mmHg

HOW TO MEASURE BLOOD PRESSURE

 Taking a Reading

Read "Suggestions before Measuring" and "Applying the Pressure Cuff" before taking a reading. Always apply the pressure cuff before turning on the device.

Step 1- Press the

button. All the LCD display symbols will appear with a long “beep” sound (Fig. 28). Then cuff begins to inflate automatically.

Step 2- After the cuff pressure is reached, the cuff begins to deflate. When detecting pulse, the Pulse Symbol “

” will flash,

along with a beeping sound during measurement. (Fig. 29)

Note: If a higher pressure value is needed, the monitor will stop deflation and inflate again.

Step 3- After the measurement, the monitor displays the systolic pressure, diastolic pressure, and heart rate. (Fig. 30)

Step 4- Press

button to switch off. Or it will switch off

automatically after three minutes.
