Frequently Asked Questions - SCA BA01 V2 SENCOR

How do I perform a breath test?

Wait for the preheat phase (about 25 seconds) until the display shows READY and the BLOW indicator flashes. Then press and hold the START button and blow steadily into the tube for at least 6 seconds until a short sound signal is heard. Release the button and read the result.

What do the display symbols and colors mean?

PH = preheat; Wait = countdown; READY = device prepared; BLOW = blow now. Result: 0.0 (green backlight) = low value <0.1‰; numeric value with NO DRIVING flashing and alternating green/red backlight = warning (≥0.2‰); HI and NO DRIVING = high value >4‰.

Why does the device show 'Er' error?

The Er error indicates incorrect handling, such as not pressing and holding the START button during the test. Press any button to stop the error sound signal and try again.

How often should I calibrate or check accuracy?

It is recommended to have the accuracy of the device tested after one year of use. With more frequent use, the sensor lifetime may be used up and results may become inaccurate.

Can I use the breathalyzer immediately after drinking alcohol?

No, you must wait at least 15 minutes after consuming alcohol before testing. Using it sooner can damage the detection sensor and cause inaccurate future measurements.

How do I clean the device?

Rinse your mouth with clean water before use. To clean the sensor, use the auto-cleaning function: remove and reinsert batteries to start a 5-minute cleaning cycle. Also, avoid blowing smoke, food, or liquids into the mouthpiece.

What is the auto-cleaning function and when should I use it?

Auto-cleaning removes residual alcohol from the sensor. It is recommended if the device has not been used for more than 2 weeks. To start, remove and reinsert batteries; the cycle takes about 5 minutes and ends with a sound signal.

What should I do when the low battery icon appears?

Replace both batteries immediately with new AAA alkaline batteries. Using the device with a low battery may lead to inaccurate measurements.

Can I use the breathalyzer in extreme temperatures?

Use the device only in an environment with temperatures between +10°C and +40°C. Operating outside this range may damage the device and produce incorrect test results.

Are the measurement results legally admissible in court?

No, the results are informative only and cannot be used as evidence in legal proceedings. Do not rely solely on this device to decide if you are fit to drive.

Important safety measures

IMPORTANT!!!

Using the breathalyser immediately after or within 15 minutes of consuming alcohol may damage the detection sensor and there is a danger of future measurements being inaccurate. Unprofessional operation of this device is not covered by the warranty.

• Do not perform tests in strong winds or in a closed room, which is filled with cigarette smoke or contains alcohol vapours.
• If the flat batteries symbol appears on the display, replace them with new ones.
• Do not blow smoke, food or liquids into the mouthpiece.
• Use the device only in an environment where temperatures are between +10 and +40 °C. Use in an environment outside this range may damage the device and may lead to incorrect test results.
• The level of alcohol in the breath depends on many factors that change in time. The level can change already several minutes after the initial test.
• The measurement results of this device cannot be used in legal proceedings as evidence.
• The information obtained using this device is only informative in nature. We recommend that it is not used for making decisions about the ability to perform any activity requiring responsibility. Several factors (e.g. natural gas remains, smoke and undesirable breath) may influence the level of the measured values.
• Do not allow yourself or anybody else to drive a vehicle after consuming alcohol. If you have consumed alcohol always organise for a designated driver or use an alternative form of transport.
• Neither the vendor nor the manufacturer are responsible for damages caused by the use of this device.

NEVER DRINK ALCOHOL IF YOU ARE PLANNING TO DRIVE A MOTOR VEHICLE!!!

Attention: It is recommended to have the accuracy of the device tested after a year of use. With more frequent use the lifetime of the device may be used up and the measurement results may not be accurate.

As soon as the countdown is completed the display will show "READY" and a sound will be made, informing you that the device is ready for operation. At the same time the "BLOW" indicator light will start to flash on the display, informing the user that it is necessary to blow into the tube.

1. Press and hold the START button and the "BLOW" will light up and you will hear a long sound signal. It is necessary blow into the tube at the same time. It is necessary to blow into the tube with a constant force for approximately 6 seconds.

- Stop blowing as soon as you hear a short sound signal. The display will show the appropriate information.

i. A measured value lower than 0.1% BAC will be displayed as "0.0" (low value).

ii. A measured value between 0.1 % – 4 % BAC will appear on the display.

iii. A measured value larger than 4% BAC will cause "HI" (high value) & "NO DRIVING" (Driving forbidden) to appear on the display.

1. Press the START button for a short time to start another test. You may use the device again as soon as the countdown is completed and the "READY" indicator appears on the display together with a sound signal.

2. Press the START button for approximately 2 seconds to turn off the device. The device will turns itself off automatically if you do not press any button within 2 minutes.

Warning signals

Low value

A measured value lower than 0.1‰ BAC will be displayed as "0,0" (low value) with a GREEN backlight.

Warning value

The measured value equals or is greater than the warning concentrated value. A sound signal will be made and "NO DRIVING" (driving forbidden) will start flashing on the screen for about 15 seconds. The display's backlight will alternate colours – GREEN AND RED.The measured value will be shown and a message "NO DRIVING (driving forbidden) will stay lit on the display.If the measured value is greater than 4 ‰, "NO DRIVING" (Driving forbidden) and "HI" (high value) will appear on the display. Press the MODE button to cancel the sound signal.IT IS FORBIDDEN TO DRIVE if the low warning value is exceeded.

Important notices

• To ensure accurate measurement results it is necessary to perform so-called auto-cleaning if you have not used the device for longer than 2 weeks (especially before first use). Start the auto-cleaning process by removing the batteries and reinserting them and turning on the device. The indicator "AUTO CLEANING" will start to flash. The auto-cleaning process takes approximately 5 minutes and there will be a countdown on the display for during this time. A sound signal will be made in the final minute of the auto-cleaning. The device will automatically turns itself off after 1 minute and the auto-cleaning process will be completed. Check that no residual alcohol has remained inside the space for blowing tube before performing a test.
• If you press the START button for approximately 2 seconds you will end the auto-cleaning process and turn off the device. Or press the START button for a short time to start measurement and to skip the auto-cleaning function.
• To achieve accurate measurements you should check that there is no residual alcohol in the device before using the device. You can inspect the device until "LO" (low value) appears on the display. You can achieve this by pressing the START button once. Press and hold the START button for several seconds and blow into the blowing tube. If necessary you may shake the device back and forward several times, which may remove residual alcohol from the device.
• After 4 repeated tests let the device rest for 2 minutes.
- If the message "Er" flashes on the display for longer than 5 seconds, it may indicate incorrect handling:

- You did not press and hold the START button during the test.

- Press any button to end the error sound signal.

• If you will not be using the device store it in a dry place.
• If the low battery condition indicator light starts flashing, the measurement is not accurate and it is necessary to replace the batteries without delay.
• If the difference between two subsequent measurements is greater than 0.1‰, you must repeat the measurement.
