Troubleshooting - VOLTCRAFT CO-60 Bedienungsanleitung

b) Air quality display in traffic light colours
Air quality is shown using a traffic light display with 3 coloured LED's. The following displays are possible:
Green LED: The CO -concentration is below 800 ppm. Air quality is good.
2
Yellow LED: T he CO -concentration is between 800 and 1500 ppm. Air quality is ok. It is recommended
2
ventilating the room soon.
Red LED: T he CO -concentration is above 1500 ppm. Air quality is bad. It is necessary to ventilate
2
the room.
If the warning signal is not muted, another additional audio sound is emitted.
c) Muting the audio sound.
At a CO -concentration of more than 1500 ppm, an audio sound is emitted. This sound can be muted by
2
pressing the "MUTE"-key (4).

TROUBLESHOOTING

The display indicates "ERR3":
• The ambient temperature is lower than 0 °C or higher than +50 °C.
Confusing symbols on the display:
• Disconnect the ambient air indicator from the operating voltage.
No display:
• Check the power supply.
• E ither use the enclosed power supply or alternatively, a so-called high-power USB port that delivers a
minimum current of 500 mA.
CLEANING AND MAINTENANCE
The device requires no servicing on your part, apart from occasional cleaning.
Use a soft, antistatic and lint-free cloth for cleaning. Do not use abrasive or chemical cleaners.
Do not apply too much pressure on the display to avoid scratch marks.
DISPOSAL
Electronic devices are recyclable waste materials and must not be disposed of in the household
waste! Dispose of an unserviceable product in accordance with the relevant statutory regula-
tions.
