Do not discard the anti-static bag. The Brj-502 is sensitive to ESD. Always ground yourself before handling the unit.

Many users overlook the firmware update section in the Brj-502 Manual. However, manufacturers release updates to fix PID algorithm stability and communication glitches. The manual outlines two methods:

Proper placement is critical for the BRJ-502 to function effectively, as different gases have different weights: For Natural Gas (Methane) : Since it is lighter than air, install the detector 30cm below the ceiling and within 1.5 meters of the gas source. For LPG (Propane/Butane) : Since it is heavier than air, install the detector 30cm above the floor and within 1.5 meters of the gas source. Warm-up Period : Upon plugging it in, the device requires a 150 to 180-second warm-up
