HBL-22 Installation instructions of cardioid breathing lamp Kit Tools required Electric iron 30W Solder wire 0.8mm Multimeter Tweezers Diagonal pliers matters needing attention: Check and identify the quantity and specification of components according to the list of components. Use a multimeter to check and confirm all resistance values. Confirm the polarity of the components and the installation direction on the circuit board in advance 1. Installation of resistance: refer to the right delivery list or the component number of circuit board, and install the resistance corresponding to the circuit board 2. Install triode: pay attention to the direction when installing triode. 3. Installation of electrolytic capacitor: during installation, pay attention to the positive pole of capacitor, the opposite type pad or the + pole of silk screen 4. Install the power switch: pay attention to the direction of the notch at the bottom of the switch corresponding to the mouth shaped silk screen on the circuit board. 5. Install adjustable resistor: install 50K blue white adjustable resistor to VR1 6. Installation of integrated circuit: during installation, pay attention to the gap of integrated circuit corresponding to the gap of circuit board screen printing. 7. Installation of LED: pay attention to the difference between positive and negative poles of LED (the long foot is the square pad of the circuit board corresponding to the positive pole). 8. Install the optional power cord or battery box: weld the red wire to +. The black wire is welded in the following figure. 9. Check before power on: After welding the circuit board, it is necessary to check whether the components of the circuit board are installed reversely, empty soldering or short circuit. After the inspection, the machine can be powered on and operated. The power supply of this machine is dc4-6v. Any USB interface can be used for power supply, or three ordinary dry batteries can be used for power supply. Attention! The supply voltage of red LED version is slightly lower than that of other color LED. Red power supply 4V is recommended. Other colors can be 4v5v6v.WPS 演示
