4. Operation & Function
4.1 Turn on self check and preheating process
Press the button for 4s and then release it. the LCD
screen of the detector is turned on and the welcome interface is
displayed. The detector automatically performs self-test of the
sound, light and vibration alarm signals, displays the system
information and performs the preheating countdown. The above
information can be used to confirm the integrity of the detector
performance.
4.1.1 After the detector is warmed up and
enters the power-on state, the normal detection
state of the detector is shown in Figure 1. (The
display mode varies according to the position of
the sensor, and the gas in the figure represents
methane.) Fig.1
