1. Properly install 3 AA batteries (included to the set) observing the correct polarity + -.
2. The device will beep one time.
3. The device will start calibration (heating up of the sensor). Diodes (red, green and yellow) will all
flash one by one and you will see "888" on the backlit display.
4. After approximately 1-2 minutes the backlight will be off and the display will show "0 ppm".
5. The detector will turn into standby mode.
6. The green diode will flash every 4 secs. indicating that the device is operational, and the display will show
ppm value.
7. Do not press the TEST button when the sensor is heating up.
8. When the sensor is fully operational, test the device with TEST button.
TEST OF THE DEVICE – at least once per week.
1.Regular testing of the detector is required to check if its power supply is in running order and proper operation of the
device.
2. Press the TEST button.
3. The backlight of the display will be turned on and information will be presented on the screen.
4. You will hear four beeps and the red ALARM diode will flash four times at the same time. The device will display the
highest CO concentration which has been detected since it was tested for the last time with a TEST button.
5. The device will shortly beep one time and it will start self-testing. The screen will display information, as presented in
table 1, and all diodes, red, green and yellow, will flash one by one.
6. When the self-test is successfully completed, the screen will display "PAS" with three beeps and all three diodes will
flash simultaneously three times. The screen will display "CO" with no backlight and then "0ppm".
7. If the self-test was faulty, the screen will display "Err", the yellow diode will flash two times and the buzzer will beep two
times at the same time. The above will be repeated every 60 seconds.
8. When testing the device make sure its sound is well heard in all bedrooms.
9. Never use open fire to test the device.
10. Never place the device close to your ears when detecting or testing as it may cause serious damage to your hearing.
