dynamo & solar radio

Working principle:

This product adopts the principle of the hand cranking and Solar-energy for power generation, it change its built-in 300mAh/2.4V Ni-MH battery. Use the circuit with high-powered Radio CMOS chip CXA1691BM, via the third class switch to switch

frequency: FM-AM-WB (weather frequency), handing the knob to tune the frequency and volume, the sound will be output via the speaker or earplug double ways.



Product function:

1. Crank by hand for power generation

2. Solar energy for power generation

3. FM/AM/WB radio function



Use method: 

1. Cranking for charge: Unlock the handle, hold the unit and crank the handle by another hand at the speed of 2 to 3 circles per second for about 1 minute 

2. Charge by solar-energy : put the unit under the sunshine or blazing light to charge

the built-in battery  

3. Reception of radio:

1) Turn the volume switch Clockwise, a crack sound will heard to show power on, then turn to make a clangorous sound 

2) Turn "FM/AM/WB switch" to find the wave band which you want 

3) Turn "tune knob" select station 

4) If the radio is inefficient, FM can draw out and turn the antenna, AM can turn the unit to improve the effect of radio 

5) Close the radio; turn the volume switch anticlockwise, a crack sound will heard to show power off
