It sounds like you have not bound the drone to the transmitter yet. If that's the case there is a little button on the drone receiver that you need to press while the transmitter is on. They should then bind and the beeping should stop.

Thanks for the reply!
Unfortunately, the link on the post is to a pdf file for the manual for battery charger. Also I tried linking the transmitter and receiver. I inserted a screwdriver into the little hole in the receiver and pressed for 1 second. It flashed twice and the LED became constant red indicating it is linked. But it still is not working. When I plug in the battery to the drone is it supposed to make beeping noise from the 4 arms? When I turn on the main switch it still the same status when I first posted in the forum. Front arm blue light is on, rear arm light is flashing red, beeping coming from arms, tail LED is rotating blue, red, green. I wonder if I have a defective circuit board or receiver?

Thanks Mr T.
I have one last question to ask before calling c/s. I can hear the beeping noise coming from 3 of the 4 motors. The rear right motor is not beeping. I switched the motor cable to the rear left esc and vice versa. When I connect the battery the rear right motor still does not beep. Could it possible that all the LED flashing light is an indicator for a motor malfunction? I f so I will contact c/s in Japan to get replacement motor.

Thanks Mr T.
Yes, before posting on the forum I did look at the two links which you provided. Very helpful. Thank you! My wife who is japanese looked on deagostini japan forum and another person like me has the same problem. I will contact c/s japan this week. Thanks for all your help!
