Common Questions
10 totalWhat error codes can appear on the GlucoRx HCT & Ketone TD-4279, and what do they mean?
The meter displays several error codes: E-b (batteries too low), E-C (wrong code strip or coding error), E-2 (expired code strip), E-U (used test strip inserted), E-t (temperature outside operating range), E-0/E-A/E-E (meter problem), and E-F (test strip removed during countdown or insufficient blood volume). For E-t, move the meter and test strip to within the operating range of 10°C to 40°C (50°F to 104°F) before retesting. If any error persists, contact GlucoRx Customer care on 01483 755133. (Page 29)
How do I set up the meter for the first time, including date, time, and alarms?
With the meter off and no test strip inserted, press the S (SET) button to enter setting mode. You will be guided through setting the year, month, and day, then time format (12h or 24h), then the hour and minute, then the buzzer on/off, up to four reminder alarms, and finally the backlight on/off — pressing M to adjust values and S to confirm each step. If the meter is idle for 3 minutes during setup, it will switch off automatically. (Page 13)
How do I replace the batteries in the TD-4279 meter?
Make sure the meter is turned off, then press the edge of the battery cover and lift it up to remove it. Remove the old batteries and insert two fresh 1.5V AAA size alkaline batteries, then close the battery cover — if inserted correctly, the meter will emit a beep. Replacing the batteries does not affect test results stored in the memory. (Page 24)
How do I calibrate the meter for β-Ketone testing?
You must calibrate the meter each time you begin a new vial of β-Ketone test strips by inserting the code strip while the meter is off and waiting for the code number to appear on the display. Ensure the code number on the display matches the number on your individual foil packet, then remove the code strip — the display will show 'OK' to confirm coding is complete. If the codes do not match, repeat the calibration procedure, and if the problem persists contact GlucoRx Customer care on 01483 755133. (Page 15)
How do I perform a blood glucose test with the TD-4279?
Insert a glucose test strip to turn on the meter and wait for the display to show the blood drop and 'GLU' symbols, then select your measuring mode (Gen, AC, or PC) by pressing M. Lance your fingertip, wipe away the first drop of blood, and gently apply a second drop of at least 1.0 microliter (μL) to the absorbent hole of the test strip at a tilted angle until the confirmation window is completely filled. Do not remove your finger until you hear a beep, then read your result after the meter counts down to 0. (Pages 19–20)
When should I perform a control solution test on my meter?
You should perform a control test when you first receive the meter, at least once a week for routine checks, when you begin using a new vial or foil packet of test strips, if you suspect the meter or strips are not working properly, if results are inconsistent with how you feel, when practising the testing process, or if you have dropped or may have damaged your meter. The control test range printed on the test strip vial is for control testing only and is not a recommended range for your actual blood glucose or ketone level. (Page 16)

3 Dear GlucoRx HCT & Ketone TD-4279 System Owner: Thank you for purchasing the GlucoRx HCT & Ketone Blood Glucose Monitoring System. This manual provides important information to help you to use the system properly. Before using this product, please read the following contents thoroughly and carefully. The System measures both blood glucose and β-ketone. Regular monitoring of your blood glucose and β-ketone levels can help you and your doctor gain better control of your diabetes. Due to its compact size and easy operation, you can use the GlucoRx HCT & Ketone Blood Glucose Monitoring System to easily monitor your blood glucose and β-ketone levels by yourself anywhere, any time. If you have other questions regarding this product, please contact GlucoRx Customer care on 01483 755133. Intended Use This system is intended for use outside the body (in vitro diagnostic use) by people with diabetes at home as an aid to monitoring the effectiveness of diabetes control. It is intended to be used for the quantitative measurement of glucose (sugar) in fresh whole blood samples from the finger, and to measure β-hydroxybutyrate (ketone) in fresh whole blood samples from the finger and palm. It should not be used for the diagnosis of or screening for diabetes mellitus. The test for haematocrit (HCT) as part of the system, is intended for use in the in vitro quantification of packed red blood cell volume fraction in capillary whole blood as an aid in monitoring the status of total volume of red blood cells. The test reading of haematocrit (HCT) is used only to determine whether the blood test sample is within the acceptable range of blood glucose system. It should not be used for the diagnosis of anaemia or erythrocytosis. Version 2.0 2015/09 311-4279300-006

Before You Begin
Important Information ● Severe dehydration and excessive water loss may cause readings which are lower than actual values. If you believe you are suffering from severe dehydration, consult a healthcare professional immediately. ● If your blood glucose or β-ketone results are lower or higher than usual, and you do not have any symptoms of illness, first repeat the test. If you have symptoms or continue to get results which are higher or lower than usual, follow the treatment advice of yourhealthcare professional. ● Use only fresh whole blood samples to test your blood glucose or β-ketone. Using other substances will lead to incorrect results. ● If you are experiencing symptoms that are inconsistent with your blood glucose or β-ketone test results and you have followed all the instructions given in this owner’s manual, contact your healthcare professional. ● We do not recommend using this product on severely hypotensive individuals or patients in shock. Please consult your healthcare professional before use. ● The measurement unit used for indicating the concentration of blood or plasma glucose will have molarity (mmol/L). The
approximate calculation rule for conversion of mmol/L in mg/dL is: For example: 1) 120 mg/dL ÷ 18 = 6.6 mmol/L 2) 7.2 mmol/L x 18 = 129 mg/dL approximately. ● The HCT is the volume percentage (%) of red blood cells in blood sample. The Hb is haemoglobin (g/dL) levels in blood sample. The approximate calculation rule for Hb is: Hb= HCT*0.34 (Note: Haematocrit =HCT; Haemoglobin=Hb) mg/dL mmol/L Divided by 18 Times 18 = mmol/L = mg/dL

Before Testing
Calibration You must calibrate the meter every time you begin to use a new vial of β-Ketone test strips by setting the meter with the correct code. Test results may be inaccurate if the code number displayed on the monitor does not match the number printed on your individual foil packet. How to Code Your Meter (for β-Ketone test)(b)Notice:
Make sure the code number on display, and individual foil packet are the same. The code strip should be within the expiry date, otherwise an error message may appear.Notice:
The codes used in this manual are examples only; your meter may display a different ketone code.
16 Control Testing Our Glucose Control Solution contains a known amount of glucose that reacts with the glucose test strips and is used to ensure your meter and glucose test strips are working together correctly. Do a control test when: ● you first receive the meter, ● at least once a week to routinely check your meter and test strips, ● you begin using a new vial or new individual foil packet of test strips, ● you suspect your meter or test strips are not working properly, ● your blood glucose or ketone test results are not consistent with how you feel, or if you think the results are not accurate, ● practicing the testing process, or ● you have dropped or think you may have damaged your meter. Test strips (e), control solution (f), lancing device (g) or sterile lancets (h) may not be included in the kit (please check the contents in your product box). They can be obtained separately from GlucoRx Customer care (telephone 01483 755133). Please make sure you have all items needed for a blood glucose or ketone test beforehand. Performing a Control Solution Test To perform a control solution test, you will need: (d), (e), (f) or (p).

21 Alternative Site Testing (for β-Ketone Test) In addition to using your fingertips, you can test on your palms. Important: There are limitations with AST (Alternative Site Testing). Please consult your health care professional before you perform AST. Suggested Test Areas for the Hand When to use AST? Food, medication, illness, stress and exercise can affect ketone levels. Capillary blood at the fingertip reflects these changes faster than capillary blood at other sites. Thus, when testing ketone during or immediately after a meal, physical exercise, or any other event, take a blood sample from your finger only. We strongly recommend that you perform AST ONLY at the following times: ● In a pre-meal or fasting state (more than 2 hours since the last meal). ● Two hours or more after taking insulin. ● Two hours or more after exercise. Do NOT use AST if: ● You think your ketone is low. ● Your AST results do not match the way you feel. ● Your routine ketone results often fluctuate.

31 The β-Ketone test measures Beta-Hydroxybutyrate (ß -OHB), the most important of the three β-Ketone bodies in the blood. Normally, levels of ß -OHB are expected to be less than 0.6 mmol/L. ß -OHB levels may increase if a person fasts, exercises vigorously or has diabetes and becomes ill. If your β-Ketone result is 0.0 mmol/L, repeat the β-Ketone test with new test strips. If the same message appears again or the result does not reflect how you feel, contact your healthcare professional. Follow your healthcare professional’s advice before you make any changes to your diabetes medication programme. If your β-Ketone result is between 0.6 and 1.5 mmol/L, this may indicate development of a problem that could require medical assistance. Follow your healthcare professional’s instructions. If your β-Ketone result is higher than 1.5 mmol/L, contact your healthcare professional promptly for advice and assistance. You may be at risk of developing diabetic ketoacidosis (DKA). Please consult your doctor to determine a target range that works best for you.
