Important Safety Information
Always cut off power before mounting, removing, and cleaning the monitor.
Mounting and Wire Connection

Do not mount it behind the door, in the corner or near heat source, diffuser or any steam source, in direct Sunlight;
Also do not mount it near the garbage bin, gas oven to prevent the evaluation error of the alarm.
Cut off power and mount the wall plate as below steps:
Put a flat head screwdriver deep inside of the hole on the bottom of the monitor casing, then depress the clip light
to remove the face plate from the wall plate according to the step 1-3 in the figure-1
Mount the monitor on the wall and height from the ground is 1.2m 1.3m, please see the mounting dimension
and fixing hole in figure-3.
Connect wires to terminal strips, (see figure 4) Make sure wiring connection correct and secure.
After Finishing the mounting, follows the step 4-5 in the figure 2 to close the cover.

Operations
Turn on the power, a red light at low position of the cover can be seen, meanwhile the LCD screen activated in green.
The measured temperature and the relative humidity displays on the upper line of the LCD and the second line is
the VOCs value. The VOCs value will be started from 0.0 and keep rising until reaches at a fixed value which is the
measured VOCs value. If the alarm is used firstly or uses again after power off for a long time(more than one month),
the warm up time is 72 hours, then the measurement will be steadily. In normal operation,
the warm up time is 1 hour.
Touch button: The touch button is used to operate the alarm as below table.
