Operating Characteristics:
First, after the battery alarm Shanghai. Will issue a sound, but also quickly flashed red, LED display 888 جزء في المليون, indicating that the battery is installed correctly, the green light flashes about every 30 ثواني, the display exterminate, when the concentration exceeds 30 ppm display lights
ثانية, press the test button, the alarm will sound, indicating that carbon monoxide alarm is energized and the line? Rice Bru bald #?
Third, when the low battery alarm every 30 seconds will send a sound, or LED display is to remind you to replace the battery LB
Fourth, after the alarm alarm will write down the value of the last alarm, then press the button that value will be displayed, the green light will flash one second once again the key to return to the reset state.
