Product selling point:
1. Made of material, durable and practical.
2. The appearance is small and beautiful.
3. Wide application.
4. With power-off memory function.
6. With power saving function.
7. The circuit board is made of FR4-A high-quality PCB, and after tin plating, it is high-quality and beautiful.
Parameter:
Working voltage: DC4.5V-5.5V
Board size: 7.7CMX6.1CM
Shell size 8.4cm*6.8CM*5.2CM
Speaker: 5W8 Euro
FM range: 87MHZ-108MHZ
FM step: press the step to 0.1MHZ, long press the FM key to continuously add and subtract
Function: digital display frequency function, power-off memory function, power-saving function
Power-off memory function: After the power is turned off, the power is turned on again, and the radio station before the power-off is played.
Power-saving function: After each power-on or pressing the FM button, the digital tube displays the frequency for 5 seconds, and the digital tube display will be automatically turned off after 5 seconds. There are two reasons for this design, 1 is to save power, and 2 is to display the digital tube. Time will interfere with the sound, and the sound is more beautiful when the digital tube display is turned off.
Note: The DC socket power supply is positive and negative outside, do not connect it in reverse.
Installation steps:
1. Lock on the board with 4 M3*8 screws
2. Lock a 10MM copper post on each of the 4 screws in step 1
3. The front acrylic plate of the shell is fixed on the copper column
4. Install the left acrylic plate
5. Install the acrylic sheet on the other 3 sides
6. Use 4 M3*10 screws to lock the speaker to the acrylic plate on the back of the case
7. Finally, install the back panel on it.
The difference:
The module used in this radio has two chips, 5767 and 5807. The 5807 is an upgraded version of the 5767. The hardware and software of the two chips are compatible and can be replaced with each other. In terms of signal, 5807 will be slightly better than 5767, other parameters are the same. You can ly choose the chip you want.
