6.1 On the remote controller, there are totally fives buttons as follows:
“Setup”, “Confirm”, “Cancel”, “+” and “-”. On the spot, it's forbidden to
replace the batteries.
Note: “Setup”, “Confirm” and “Cancel” are single-spring buttons.
These buttons can only be springed once even if you press them
continuously, and the interval between two springs should not be less
than 1 second. “+” and “-” are continuous-spring buttons and can be

pressing “Confirm”. After setting, press “Cancel” to return to the
normal mode. Effective setting can be kept till the next setup, even if
without power.

5.4 After the correct wire connection, take out the useless wire from
the enclosure. Then tighten the compaction circle, rubber air-proof
circle and wire. Explosion-proof soft tube can also be connected with
the device directly.
Note: The size of the wire between the controller and detector should
be not less than 6mm, and the distance should be note more than
1000m.
5.5 After checking all the connection well, install the display PCB and
the front cover. Make sure O-type circle is put on and connected with
the cover tightly.
4.1.4 The position should be within 1m around the possible gas
leakage area, such as valve, pipe connection point, gas outlet place.
Please try to install it nearer to the above places, but avoid
influencing the working of the other equipments. Please avoid the
environment of high temperature and humidity. Also please keep it
from water swashing, oil and mechanical damage. Please also
consider the convenience of maintenance and calibration.
4.1.5 For large scale detection, we suggest install 1pc every 10-12
square meters, so as to get the best detection result.
