 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.
This user’s manual contains important information that you must know about
your system. Please read it carefully.

 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 /
10 mmol/L
Bedtime 100-140 mg/dL /
5.6-7.8 mmol/L

BEFORE YOU START

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:

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 oC (39oF) and
40oC (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.

 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.
Step2- Insert four 1.5V AA size alkaline
batteries. Make sure the + (positive) and
–(negative) marks match as indicated
in the battery compartment. (Fig. 4) If
inserted correctly, you will hear a "beep".
Caution!
Do not use different type, date or brand name batteries together. Use only
new batteries of the required size and type.
Replacing the batteries does not affect previous test results stored in the
monitor. But you may need to update the settings.
Batteries might leak chemicals if not used for a long time. Remove the
batteries if you are not going to use the device for an extended period (i.e., 3
months or more).
