- Alarm warning (red light).
- Low CO concentration warning: when the
concentration is higher than 30PPM for more than
60 minutes, or higher than 40PPM for more than 40
minutes, a warning will pop up. When the concen-
tration is below 25PPM, the alarm will stop sounding
automatically.
Note: the low CO concentration warning is different
from the alarm warning
- Power indicator: flashes approximately every 45
seconds (green light).
- Error warning: when an error occurs, a warning
appears within 3 minutes (yellow light)
Information and power indications:
1. LCD Info: Display shows CO concentration,
battery level, error warning, end of life, power on
warning, and test run.
2. Power Indicator – When batteries are installed
and the detector is powered on, it will display a
message indicating that everything is working
properly. This product has a battery behavior that
uses 3 AA alkaline batteries. The detector will turn
on between 20/30 seconds after installing them.
Note: it must be turned on in clean air without
CO, or an alarm warning may come out.
3. Battery level: When the detector is on, it
flashes approximately every 45 seconds. If a low
concentration is detected and the alarm has not
been triggered, the interval will be less than 45
seconds.

4. CO concentration: the display shows the CO
concentration in PPM.

When it is less than 10PPM it will display
'0PPM', and if it is greater than 550PPM it will
display 'HCO'.
Note: it is very dangerous if it shows more than
550PPM.
When CO concentration is above 30PPM for
more than 60 minutes or above 40PPM for more
than 40 minutes, a low concentration warning
will be sent, and when the concentration is below
25PPM, the alarm will end automatically. In daily
life it can happen that there are low levels of CO
for example by smoking cigarettes, or having
lighted candles and appliances that burn gas.
Although it may not harm people, prolonged
exposure to low levels of CO can affect the health
of children, pregnant women, the elderly, or the
infirm. This warning is to help them avoid such
exposure.
5. Test Operation: indicates that the test is in pro-
gress. When the detector is in operation, pressing
the 'TEST' button will perform a test.
Note: it is recommended to test once a week to
ensure proper operation.
6. Error warning: If there is a fault, a warning will
be activated in 3 minutes and will be done once a
minute until the error is eliminated.
The warning may be triggered by a short circuit
in the sensor or electrical damage. Volatile gases
such as ethyl alcohol can affect the sensor and
cause temporary failure. It is recommended to
turn off the unit and place it in clean air for 24
hours, if it does not work after that time it means
that it has permanent damage.
Note: The product must be repaired by a profes-
sional who is authorized by the manufacturer.
