Your Accu-Chek Active blood glucose meter is a state-of-the art precision instrument that will enable you to test your blood glucose simply and with confidence.
Before using your Accu-Chek Active meter or Accu-Chek Softclix finger pricker for the first time, please refer to the Getting Started Guide included in this pack. Should you require further information, please study this reference manual.
This manual may tell you a lot of what you know already, but it will also introduce many features that will be new to you. At the end of this introduction you will find a brief summary of your meter’s main properties and functions. Each of the functions will be described in more detail later in this manual.
If there are any other points you are unclear about – Chapter 10.4 provides the address and telephone numbers of our customer support and service centre.
Last update: 2006-11
1 Introduction
Page 11
Testing in record time: With a testing time of about
5 seconds, your Accu-Chek Active is one of the fastest blood glucose meters available.
New design: Your new Accu-Chek Active was designed for good
looks, and ergonomic functionality.
Tiny blood sample: Your Accu-Chek Active requires only a tiny
drop of blood – 1 to 2 µL – if you apply the blood drop to the middle of the test pad. If at any time the drop you apply is too small, the meter will detect this and issue a warning.
Easy to operate: No need to press buttons when you carry out
the test.
Easy-to-use data analysis function: Accu-Chek Active has a
200-value memory for saving results (together with date and timestamp) as well as an infrared interface for communicating with a PC running a suitable analysis program.
1.1 The meter’s main features at a glance
Page 12
Integrated data evaluation: From the results stored in memory
your meter can calculate the average of your blood glucose results over the last 7 or 14 days.
Out-of-meter dosing: After activating the test cycle you may
remove the test strip to apply blood (e.g. from an earlobe), and then insert it again in the meter.
Accurate results: Application of blood to the test strip starts a
colour reaction. The final colour is accurately read (measured photometrically) by the meter’s optical system and the result is converted to a blood glucose value.
Dependable coding: Each pack of test strips contains a coding
chip that holds all of the important information that is needed to evaluate the strips from that particular pack. Whenever you open a new pack of strips, simply insert the new coding chip in the coding chip slot.
1.1 The meter’s main features at a glance
Page 13
Easy-to-read display: Numbers and messages are clearly
presented on a spacious display screen. Clear symbols give you additional easy-to-follow instructions.
Intelligent power supply: Accu-Chek Active shuts off automati-
cally after 1–2 minutes of non-use. Naturally, all of your results and other data remain safe in memory. Also, you receive a warning when the battery has only enough power for about another 50 tests.
Page 14
This manual will help you get to know your new Accu-Chek Active meter step by step. It will provide you with all the information you need to operate, troubleshoot, clean and care for your meter. It is important to remember that, in order to keep your meter in tip-top condition, you need to comply with the care instructions in addition to following the correct operating procedures. Accu-Chek Active is a precision instrument. Dirt or the wrong cleaning agent can impair its function.
Please read carefully all text in this manual that is preceded by the following symbols:
This warns of a situation that may pose a risk to your health (e.g. as a result of you calculating the wrong insulin dose).
1.2 About this reference manual
Page 15
This symbol indicates that your meter is at risk of being damaged.
This symbol highlights important information that will help you get the most out of your meter.
We recommend that you start by familiarizing yourself with all of the elements of your Accu-Chek Active shown on pages 4–7 of this manual. Practise all of the operations described in this manual, and also practise testing. That way you can feel confident in testing whenever you need.
Page 16
As you will have gathered, your Accu-Chek Active meter can do much more than just measure blood glucose. It offers a number of additional functions, which fall into three groups. “Mode” refers to a group of functions that you can call upon. You select a mode simply by turning on the meter or by the way in which you turn it on. Detailed information on the various ways of turning on your meter and the options available in each mode is provided later in this manual.
2 Modes
Page 17
This is the main mode in which you will use your Accu-Chek Active meter and is used exclusively for testing your blood glucose. By inserting a test strip in the test strip guide, you automatically enter this mode.
2.1 Test Mode

3.2 Basic settings
Page 22
Accu-Chek Active comes in 2 versions.
When you first turn on your Accu-Chek Active, please be sure to check that the meter is set to display mmol/L (for millimoles per litre) above the large numerals in the display (
888
). Ask your doctor if you do not know which is the right unit for you. If this is not displayed, please contact the Accu-Chek Customer Careline free on 0800 701000 (UK) or 1 800 709600 (Ireland) for a replacement meter.
3.2 Basic settings

Turning the meter on in Set Mode
You use only the M and S buttons on the front of your Accu-Chek Active to enter the desired settings.
Briefly press the S button (for less than 3 seconds). Accu-Chek
Active is now turned on and in Set Mode.
In the display you see the following:
the current time display format (24h/12h)
flashing: the current time, or 0:00 (a.m.) when you turn on the
meter for the first time
flashing: the current date, or 0.0 (0-0) when you turn on the
meter for the first time
Page 26
3.2 Basic settings
Page 27
The way in which the date and time are displayed from here on depend on the chosen display format.
If you wish to change the time display format, press the M
button now. This allows you to choose between 24h and 12h display format.
When you see the desired format, press the S button once to
proceed to the date and time settings.
Page 28
3.2 Basic settings
Page 29
Setting the date and time
The procedure for setting the date and time is essentially the same for all units of time (day, hour, etc.):
Use the S button to select the unit of time you wish to change.
The unit will flash, indicating that it is ready to be changed.
Use the M button to modify the unit of time selected.
Pressing the M button once will increment the value of the unit
by one (one hour, one minute, etc.). Settings where there are only two options (time format, beep tone) are simply toggled backwards and forwards when you press the M button.
Keeping the M button depressed enables you to fast-scroll the
value forward.
Page 30
3.2 Basic settings
Page 31
Confirm the setting by pressing the S button again. The display
moves on automatically to the next unit of time, which again flashes.
Use the same procedure to set all the remaining units of time.
The date and time are set in the following sequence: hours –> minutes –> year –> month –> day
The year is already set. Press the S button to confirm. The meter automatically recognises, and allows for, leap years.
Page 32
3.2 Basic settings
Page 33
Setting the beep tone
After you have set the day and pressed the S button, you can either enable or disable the beep tone.
Press the M button to turn the beep tone on and off.
Press the S button to complete the settings procedure.
Check that all the settings now shown on the display are correct. Press the S button again to turn off your Accu-Chek Active meter. If any of the settings are incorrect, you may repeat the settings procedure (after turning the meter on again).
Page 34
The properties of the Accu-Chek Active test strips you use with the meter may differ very slightly from one pack to another (because of batch-to-batch differences). Your Accu-Chek Active meter must be programmed to allow for these differences in properties in a process known as “coding”. All the information relating to the strips in a particular pack of Accu-Chek Active test strips is held in the coding chip that comes with that pack.
3.3 Coding
Page 35
Each time you open a new pack of test strips, you will need to insert the coding chip that came with that pack into your meter. Coding chips from other packs contain the wrong information for your new strips, so test results will be incorrect. Leave the coding chip in the meter until you have used up all of the test strips from a particular pack.
Check that the three-digit code (e.g.
133
) printed on the chip matches the code printed on the label of the container the test strips came in. When coding is complete, your Accu-Chek Active meter will display the code number.
Page 36
3.3 Coding
Page 37
Inserting the coding chip
When coding, leave your Accu-Chek Active meter turned off.
Take the new coding chip from the pack of test strips.
Gently slide the coding chip into the slot on the side of the
meter
(see parts summary).
Ensure that you push the coding chip fully home.
That’s all there is to it!
When you subsequently perform your first blood glucose test with the new coding chip (and new test strips), check that the code number you see in the display is the same as the number printed on the container the test strips came in. For further information please refer to the next chapter.
Page 38
4.1 Materials for testing blood glucose
Please have the following items ready to carry out the test:
your Accu-Chek Active meter with the coding chip inserted,
the pack of Accu-Chek Active test strips you took the coding
chip from,
a suitable finger pricker (such as the Accu-Chek Softclix
finger pricker and Accu-Chek Softclix Lancet).
With your Accu-Chek Active meter use only Accu-Chek Active test strips. Any other test strips will give incorrect results. Sometimes the error can be significant, causing the wrong therapeutic decision to be taken and so producing adverse health effects!
4 Testing blood glucose with your
Accu-Chek Active meter
Page 39
If you are not yet familiar with the concept of blood glucose self­monitoring using a meter, practise first by carrying out a quality control test as described in Chapter 6. A quality control test is carried out in the same way as a normal test, but with control solution (a standardized glucose solution) instead of blood.
Carefully read the pack inserts that came with the test strips
and the finger pricker.
Thoroughly wash and dry the site you intend to collect blood
from. Any moisture remaining can dilute the blood and so produce an incorrect result.
Remove a test strip from its container. Close the container
immediately. The cap contains a drying agent which ceases to function if the container is left open, rendering the test strips unusable.
4.2 Preparing for the blood glucose test
Page 40
4.3 Performing a blood glucose test
Page 41
Check the round control window on the back of the test strip with the colour scale printed on the test strip container. The colour of the control window must match that of the colour interval at the top (0 mmol/L). If the test strip shows a different colour, do not use it.
Hold the test strip so that the application area and arrows are facing upwards. Gently push the test strip in the direction of the arrows into the test strip slot
of your meter, until you hear it click into place.
Inserting the test strip automatically puts the meter in Test Mode. Please remember that your meter automatically turns off after about 1–2 minutes of non-use (i.e. when no button is pressed). If this happens, remove the test strip and repeat the procedure described above with a new test strip.
Now watch the display.
Page 42
4.3 Performing a blood glucose test
Page 43
The meter carries out a display test (for details see page 87),
then shows the code number. Is this the number printed on the test strip container? If not, check that you really did insert the coding chip from the new pack. If you are using the right coding chip but the number in your display is wrong, please call the Accu-Chek Customer Careline free on 0 800 701000 (UK) or 1 800 709600 (Ireland).
If “code” is flashing and you see three horizontal bars
(
---
) instead of a number, you have not inserted the coding
chip.
Page 44
4.3 Performing a blood glucose test
Page 45
Check that the correct date and time are displayed.
Do not carry out any tests if the code number in the display is not the same as the number on the test strip pack. Incorrect coding produces incorrect results. Sometimes the error can be significant, causing the wrong therapeutic decision to be taken and so producing adverse health effects.
When the display test has been successfully completed and the code number matches, your Accu-Chek Active meter is ready for testing.
The flashing drop symbol is your cue to apply a drop of blood
(within two minutes). If you wish to apply blood while the test strip is in the meter, please read on. For out-of-meter dosing please see page 55.
Page 46
In-meter dosing
If you have opted for in-meter dosing, proceed as follows:
Massage a fingertip to stimulate the circulation and make blood
collection easier.
Use the finger pricker to prick the side of the massaged
fingertip.
Without pressing too hard, encourage a small drop of blood
to form.
4.3 Performing a blood glucose test
Page 47
Apply the drop of blood on to the middle of the orange-coloured,
square application area (pad). It is OK to touch this area when applying blood, but do not attempt to spread the blood. If you suspect the amount of blood may not suffice, you may apply a second drop within 5 seconds.
Your Accu-Chek Active meter beeps briefly (provided the beep
tone is enabled) to acknowledge application of blood and to announce the start of testing. Make sure you do not move the test strip during testing, or an incorrect result may be obtained.
Page 48
4.3 Performing a blood glucose test
Page 49
The hourglass symbol indicates that testing is in progress.
The meter beeps again after about 5 seconds to signal that
the test is complete. The result appears in the display and is automatically saved together with the date and time.
Remove the test strip from the meter, which will now
automatically turn off.
Page 50
4.3 Performing a blood glucose test
Page 51
Plausible results
Your Accu-Chek Active meter measures blood glucose within a defined range (0.6-33.3 mmol/L). Values outside this range are displayed as “Lo”- meaning the result is less than 0.6 mmol/L ­or “Hi”- meaning the result is greater than 33.3 mmol/L.
If you applied too little blood, please repeat the test with a new test strip.
Now perform a plausibility check. It is important that this check be performed within 30–60 seconds after blood was applied. Any later than this and comparison is no longer possible owing to excessive discolouration of the test strip. This colour comparison is solely for the purpose of checking the result. Therapeutic decisions must be based on the result given in the display.
Page 52
4.3 Performing a blood glucose test
Page 53
Turn over the test strip to reveal the round control window on the back.
On the label of the test strip container is a colour scale with blood glucose values printed alongside. Select the blood glucose value that best approximates the reading you obtained.
Compare the colour of the control window with the colour you selected on the label.
The colours must be a fairly close match. If there is a great disparity, repeat the test. If you cannot obtain a close match even after several attempts at testing, please call the Accu-Chek Customer Careline.
If the colours match, the result is confirmed and the test success­fully concluded. You can dispose of the used test strip with your regular domestic waste.
Page 54
Implausible results
If the displayed result does not reflect the way you feel or seems unusually high or low, or if colours do not match, please check the following:
With your Accu-Chek Active meter, are you using only
Accu-Chek Active test strips?
Have you really used a test strip from a pack with the same
code number as that displayed by your Accu-Chek Active meter?
Did you apply the drop of blood within 3 minutes after removing
the test strip from its container?
Are both the test strip guide and measurement optics clean?
4.3 Performing a blood glucose test
Page 55
Was the test strip container you are presently using kept
properly closed?
Have the test strips expired?
Have the test strips been kept under suitable temperature
conditions (i.e. not in a car in very hot or cold weather)?
If the answer to all these questions is “yes”, carry out a quality control check with a new test strip as described in Chapter 6. If this check confirms the meter is working properly, please read the instructions in Chapter 4.3 again and perform another blood glucose test with a new test strip. If you feel the new result is also implausible, please speak to your doctor about it.
Page 56
4.3 Performing a blood glucose test
Page 57
Out-of-meter dosing
The test procedure is mostly identical with “Performing a blood glucose test” on page 38. Follow the instructions given there up to the point where you are instructed to apply blood.
Clean and massage the site you intend to collect blood from
(for example, an ear lobe). This will stimulate the circulation and make blood collection easier.
Use the finger pricker to prick the selected site.
Without pressing too hard, encourage a drop of blood to form.
Page 58
Pull the strip out of the meter. The two symbols (blood drop and
test strip) are flashing. You now have 20 seconds to apply blood to the test strip and re-insert it before the meter switches off. After 15 seconds a beep tone once per second indicates that the time for measurement has expired.
4.3 Performing a blood glucose test
Page 59
Apply the drop of blood to the middle of the orange-coloured
pad. It is OK to touch this application area when applying blood, but do not attempt to spread the blood.
Gently push the test strip back into the test strip slot of your
Accu-Chek Active meter, until you feel it click into place.
Your Accu-Chek Active meter beeps briefly to acknowledge
application of blood and to announce the start of testing. Make sure you do not move the test strip during testing, or an incorrect result will be obtained.
The hourglass symbol indicates that testing is in progress.
Page 60
4.3 Performing a blood glucose test
Page 61
The meter beeps again after about 10 seconds to signal that
the test is complete. The result appears in the display and is automatically saved together with the date and time.
Testing by healthcare professionals
The out-of-meter dosing feature of the Accu-Chek Active meter makes it ideal for testing in a professional environment. For each patient use a separate lancet and finger pricker, or alternatively use the specially developed Accu-Chek Softclix Pro, or Safe-T-Pro lancet devices. Collect used lancets and test strips in a sturdy sharps container with lid. Be sure to observe all relevant Health and Safety regulations.
A potential infection risk exists. Medical staff and other persons using Accu-Chek Active to test blood glucose from more than one patient must be aware that any item coming into contact with human blood is a potential source of infection. (Please see “Protection of Laboratory Workers from Infectious Diseases Transmitted by Blood, Body Fluids, and Tissues”; Second Edition, Tentative Guideline, 1991, Document M29-T2,
Page 62
5.1 Results memory
Your Accu-Chek Active meter has a 200-value memory for saving results together with date and time. You do not need to save a result specially; the meter does it all for you. Once all the memory locations are full, the meter automatically erases the oldest entry. All results in memory are consecutively numbered from 1 (most recent) to a maximum of 200 (oldest).
5 Using Accu-Chek Active as an electronic diary
Page 63
In addition to results, your meter also stores all relevant additional information and display messages. For example, results flagged as control results are displayed together with a bottle symbol incorporating the letter “C”. Results obtained at a temperature outside the permitted range are displayed together with a thermometer symbol. Please refer to Chapter 8 for a complete list of display messages and symbols.
Page 64
5.2 Retrieving results
Page 65
To use the memory functions of your Accu-Chek Active meter, you must turn it on in Memory Mode.
Briefly press the M button (for less than 3 seconds).
In the display you see the following:
at top left, “mem” (short for “memory”)
followed by the most recent result (in memory location “1”),
together with the time and date.
Page 66
5.2 Retrieving results
Page 67
To recall earlier results (in memory locations 2-200):
Press the S button once to move back one result in time.
As long as you keep the button pressed, the number of the memory location is displayed. As soon as you release the button, the result appears.
By holding down the S button, you can scroll quickly through the

Page 69
Finding the 7 or 14 day average of glucose results
As well as just showing the results in memory, your Accu-Chek Active meter can calculate and display average values for the last 7 or 14 days.
Start by pressing the M button to turn on your
Accu-Chek Active meter in Memory Mode.
Then press the M and S buttons at the same time.
The display shows “7 day ave” at top right. The figure shown is the average of glucose results for the last 7 days.
Page 70
5.2 Retrieving results
Page 71
Then press the M and S buttons again at the same time.
The display changes; the figure shown is now the average value
for the last 14 days.
To exit from the “average” screen, press the S button. The display reverts to the last result shown before the average value.
Averages can only be calculated as long as you have set the date and time (see Chapter 3.2). Without these settings the meter cannot identify the results from the last 7 or 14 days. For safety reasons no average value can be displayed when the date has been manipulated into the future.
When averages are being calculated, all control readings are ignored.

Page 73
Clearing (erasing) results from memory
You can clear the current value (and only this) from memory. This feature is useful, for instance, if you have obtained an implausible result. Both the result and the time and date information are erased, though the memory location remains occupied.
An average value cannot be displayed when the most recent result has been erased from memory. Results arising after a value has been erased are included in calculation of the average.
Clearing the current value:
Turn on your Accu-Chek Active meter by keeping the S button
pressed for longer than 3 seconds.
The display shows “Clr” and “mem” (flashing).

For data downloading you need a suitable PC program as well as the Accu-Chek Infrared Cable. For further information please contact the Accu-Chek Customer Careline 0800 701000 (UK) or 1 800 709600 (Ireland) (see Chapter 10.4).
Data can only be evaluated on a PC as long as you have set the full date and time (see Chapter 3.2).
Your Accu-Chek Active meter has an inbuilt infrared interface
11
(see illustration on pages 6–7), permitting cordless data down­loading to a suitably equipped PC. All results in memory are downloaded each time. After download the data are still in the meter’s memory.

Downloading procedure
To download data, proceed as follows:
Set up the program and infrared cable according to
manufacturer’s instructions so you can start data transfer with a mouse click.
Position your Accu-Chek Active meter about 10 cm from the
infrared cable. Point the two infrared windows towards one another.
Turn on your Accu-Chek Active meter by keeping the M button
pressed (for longer than 3 seconds) until “PC” appears flashing in the display. This indicates the meter is ready to communicate.

Start downloading at the PC. The PC sends an instruction to the
Accu-Chek Active meter.
During active downloading, “PC” remains constant in the display
On completion of downloading, “End” appears in the display.
Following the download you can turn off your Accu-Chek Active meter with the M button, if the PC has not already shut down the meter. In the latter case the “End” message may not be displayed.

6.1 Quality control testing with control solution
To ensure your results are always dependable, you must periodically check the performance of your Accu-Chek Active meter.
Perform a quality control test:
6 Checking Accu-Chek Active
Page 83
after you have opened a new pack of Accu-Chek Active test
strips and consequently replaced the coding chip,
after you have inserted a new battery,
after you have cleaned your Accu-Chek Active meter,
if you have reason to doubt the validity of a result.
Page 84
6.2 Preparing for the quality control test
Page 85
For the quality control test, please have the following items ready:
your Accu-Chek Active meter with the coding chip inserted,
the pack of Accu-Chek Active test strips you took the coding
chip from,
the Accu-Chek Active Control solutions.
Carefully read the pack inserts that came with the test strips and the control solutions, and select a control solution.
Page 86
Remove a test strip from its container. Close the container
immediately. The cap contains a drying agent which ceases to function if the container is left open, rendering the test strips unusable.
Check the round control window on the back of the test strip
against the colour scale printed on the test strip container. The colour of the control window must match that of the colour interval at the top (0 mmol/L). If the test strip shows a different colour, do not use it.
6.3 Quality control test procedure
Page 87
Hold the test strip so that the application area and arrows are
facing upwards. Gently push the test strip in the direction of the arrows into the test strip slot
of your Accu-Chek Active meter,
until you hear it click into place.
Inserting the test strip automatically puts the meter in Test Mode. Please remember that your Accu-Chek Active meter automatically turns off after about 1–2 minutes of non-use (i.e. when no button is pressed). If this happens, remove the test strip and repeat the procedure described above with a new test strip.
Now watch the display.

The meter performs a display test lasting 2 seconds.
Check that all the segments making up the numerals (“
888
or “
88.8
”) are properly displayed. If a segment is missing,
test results may be displayed inaccurately (e.g. through
9
being
confused with
3
). If this happens, call your customer support
and service centre.
The current code number then appears in the display. Is this
the number printed on the test strip container? If not, check that you really did insert the coding chip from the new pack. If “code” is flashing and you see three horizontal bars (
---
) instead of a number, you have not inserted the coding chip. You can still do this now (while the display is flashing).
Check that the correct date and time are displayed.

When the display test has been successfully completed and the code number matches, your Accu-Chek Active meter is ready for testing. The display screen that follows signals:
That the test strip has been inserted.
The flashing drop symbol is your cue to apply the control
solution (blood in the case of a real test).
To make quality control results stand out later from blood glucose test results, you can place what is known as a “flag” against them.
Press the S button once. In the display you see an hourglass
symbol along with the control test flag (a bottle with the letter “C”). You can insert the flag at this point. If you pressed the S button inadvertently, you can press it again (before testing is complete) in order to remove the flag.

Apply one drop of the selected control solution to the test pad
of the strip.
Your Accu-Chek Active meter beeps briefly to acknowledge
application of solution and to announce the start of testing.
After 5 seconds a second beep tone indicates that testing is
complete, and the result appears in the display. If you have not already flagged this quality control result, you may do so now.
The value displayed here is an example. The result shown on your Accu-Chek Active meter will not necessarily agree.
Page 94
Now check that the displayed value is within the permitted range. Examine the test strip container and locate the “Accu-Chek Active Control” table. The table has two rows listed as “1” and “2”, as well as two columns giving ranges in mmol/L and mg/dL.
A
CCU

C
HEK® Active Control
mg/dL mmol/L

2 131 – 177 7 ,3 – 9,8
6.3 Quality control test procedure
Values are for illustration only.
Page 95
If you performed the test with Accu-Chek Active Control 1,
refer to row 1 for the permitted range.
If you performed the test with Accu-Chek Active Control 2,
refer to row 2 for the permitted range.
If the result is within the stated range, you need to still carry out a visual plausibility test. It is important that this check be performed within 30–60 seconds after control solution was applied. Any later than this and comparison is no longer possible owing to excessive discolouration of the test strip.
If the result is outside the stated range, perform a second quality control test. If the second result is still outside the range, please call your customer support and service centre.
Pull the strip out of the meter. The result is saved as a control
reading (which is ignored when the averages are calculated), and the meter switches off.

Turn over the test strip to reveal the round control window on
the back.
On the label of the test strip container is a colour scale with
blood glucose values printed alongside. Select the blood glucose value that best approximates the reading you obtained.
Compare the colour of the control window with the colour you
selected on the label.
The colours must be a fairly close match. If there is a great disparity, repeat the test. If you cannot obtain a close match even after several attempts at testing, please call your customer support and service centre. If the colours are a close match, quality control testing of your Accu-Chek Active meter has been successfully concluded. The meter is now ready to perform further blood glucose tests.
If the measurement optics or any other part of your Accu-Chek Active become soiled during testing, please clean the meter as instructed in Chapter 7.1.

6.4 Performing a full display check
longer than 3 seconds
Page 99
The standard power-on display test checks the most important display elements. To verify that all of the elements are functioning correctly, you can carry out a full test.
Press and hold down the M and S buttons together for longer
than 3 seconds.
All the elements of the liquid crystal display (LCD) are shown
at once. Either “mmol/L” or “mg/dL” will be visible depending on the country-specific setting.
Press any key to terminate the display test and turn off your
Accu-Chek Active meter. If you do not press a key, the meter will shut off automatically after about 2 minutes.
Page 100
Your Accu-Chek Active meter has no moving parts and so will not suffer any mechanical wear and tear. As with any precision instrument, however, you will need to look after it carefully to keep it at its best.
