NOTE: Refer to “3. What to do if the alarm sounds” when you hear
the sounds of the CO alarm warning.
3.4 CO alarm warning silence
During the device under CO alarm mode, pressing the TEST/SILENCE
button, it will be paused alarm sound of the device about 10 minutes.
-
tes the device is running into the CO alarm silence mode.
NOTE: The audible alarm signal will reactivate about 10 minutes
from the time the TEST/SILENCE button is operated where the con-
centration of CO surrounding the
alarm remains at 50 PPM or greater.
NOTE: The audible alarm signal cannot to silence if the alarm at
concentration above 200 PPM.
NOTE: The alarm silencing activation to once throughout a CO
alarm period.
WARNING! Before enable feature of CO alarm warning silen-

rous levels of carbon monoxide and the dwelling should be
ventilated.
3.5 Low battery voltage warning
If the device chirps once every 40 seconds, with FAULT indicator (yel-

ways displays „ „.
NOTE: When the low battery voltage warning is occur, the device
has capable of producing a CO alarm signal for at least 4 min or 30
days of low battery voltage warning signal operation.
NOTE: The device will not protect against the risk of carbon mono-
xide poisoning when the battery has drained.
3.6 Low battery voltage warning silence
When the device is under the low battery warning, pressing the
TEST/SILENCE button, it will come into a low battery voltage warning
silence status for about 9 hours, meanwhile it will appear „ „ on
NOTE: The silence feature of low battery voltage warning is tempo-
battery as soon as possible.
3.7 Fault warning
If the device chirps twice every 40 seconds with FAULT indicator (yel-

3. Understanding your CO alarm
3.1 Start up
This is preheated state, 60 seconds later the POWER indicator (green)
The LCD displays all segments 4s and count down. When the
countdown is „0“, the product goes into normal operation.
3.2 Normal operation
LCD alternately displays current CO concentration and temperatu-
re every 40s. CO concentration display range: 0~999PPM. If the CO
concentration is under 20PPM, the LCD will display „0PPM“. If the CO
concentration overruns 999PPM, the LCD will display „999PPM“. Tem-
perature display range:-9~50
℃.
If CO concentration overruns 20PPM,
the function of temperature display will be
disable.
3.3 CO alarm warning
When the device detects a dangerous level of CO, the device will emit
a loud alarm pattern. The alarm signal pattern is 4 beeps followed by
pattern. This cycle repeats as long as a dangerous CO condition exists.
