5. When the alarm sounds, it will turn off within 6 seconds after moving the detector to a space
with a CO concentration below 40PPM.
6. The alarm sound can be turned off by pressing the TEST / MENU button (<150PPM).
7. Every 2 minutes, the detector will automatically perform an error check.
TESTING:
When the CO detector is working under normal conditions, the sensor and siren should be tested
at least every month. Press the "TEST/MENU" button. The "POWER","FAULT" and "ALARM" LEDs
will illuminate. The detector will then emit 4 beeps while the red "ALARM" LED flashes 4 times.
When the display shows everything is in order.
If the sensor detects an error, the yellow "FAULT" LED will flash 2 times while 2 beep tones are
emitted. The display will now show .
RESET ALARM:
The alarm can sometimes activate because of environmental influences, for example due to smoke
with certain carbon monoxide concentrations or other chemical gaseskand. If the CO value is
below 150PPM, you can press the "TEST/MENU" button. The alarm will stop and the detector
immediately starts checking the gas again.
If the concentration is above 150PPM, it'll be impossible to stop the alarm.
The red LED continues flashing and the siren will stop for 5 minutes.
If the concentration is still above 150PPM after those 5 minutes, the alarm will continue.
LED INDICATION:
Red LED Alarm, carbon monoxide present
Yellow LED Sensor problem

BATTERY INFORMATION INDICATION:
1. Every 45 seconds, the battery is checked automatically.
2. Every 45 seconds, the green power LED will flash for as long as the battery power is higher
than 3.5 Volts. This means the battery capacity is sufficient. As soon as the battery power
drops below 3.5 Volts, a beep tone will be emitted when the green LED flashes briefly. At that
time, please replace the batteries as soon as possible.
The display also shows a battery capacity monitor:
Full
Half
Low
Empty
When empty batteries are indicated, the batteries should be replaced as soon as possible.
Use High Energy Alkaline batteries (3 x LR6 / 1.5V AA). Rechargeable batteries are not suitable.
With both the supplied batteries and most A brand batteries on the market, it will take
approximately one year before these are empty.

MEMORY FUNCTION:
This detector has a memory function for the following values:
• The maximum measured PPM value.
• The average PPM value of the past 24 hours.

Wait 5 seconds or briefly press the "TEST/MENU" button.
The display shows "clear".
Within 5 seconds, press and hold the "TEST/MENU" button for 10 seconds until
appears in the display. The memory values will now be erased.
When the batteries are replaced or briefly disconnected, the memory will also be erased.
REASON FOR SENSOR FAULT:
Faults can be caused by broken circuitry, a faulty sensor or faulty electronic parts.
SENSOR FAULT CAUSED BY CHEMICAL GASES:
When volatile chemical gases such as alcohol are the cause for error detection, this may be
corrected by switching the detector off and leave it in fresh air for 24 hours. This will restore
the sensor. If the error is not cleared after these 24 hours, the detector is faulty and should be
replaced. Don't repair the detector yourself, but have it repaired by the importer.
When the alarm is contaminated and damaged by high concentrations of chemical gases, the
sensor could be affected. This will lead to a temporary error or permanent damage. When the
alarm sounds and you can smell a chemical gas, this could be the reason. Carbon monoxide is a
colourless and odourless gas. Chemical gases do have an odour.
The following substances and gases can cause false alarms or permanently damage the detector:
Methane, propane, iso-butane, ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, acid,
ether, hydrogen, hepatic gas, sulphur dioxide, aerosol, propellant, alcohol preparation, paint,
thinner, dissolvent, bonding agents, shampoo, aftershave balm, perfume, car exhaust (cold start)
and certain cleaning agents.
