I just received my hy929. the instructions are so very vague. not enough as to know what to do. are there more instructions some place else?

Dear friend Hi again Please first charge the device for about 5 hours. when you plug in the charger, the device's red indicator lights up, and when the charging is complete, the red indicator lights out. Normally when you rotate the locator of the device, the device will turn on, and then you can hear the sound,(If it still has no sound,please replace another earphone to try). Please make sure the microphone and earphone plugs are fully plugged into the device. Insert them firmly and make sure the plugs are in good contact. Please note a very important technique to use: When you put the round microphone close to the wall or the door, be sure to keep your hand still. don't move anything, Otherwise it makes noise because the microphone is very sensitive. it needs a highly sensitive microphone to hear what's going on inside the walls,please understand. You just need to keep your hand still and then it can work well Please try again carefully. if have questions,please tell me Thank you very much Deng
