The first time I installed the machine, there was a problem

When I just arrived at the miner today, I installed it according to the instructions (antenna, height, address) to keep me from binding the helium app wallet and asking me to try again. After several attempts, I thought it was power-related, so I turned him off (the process of turning it off was as they said in discord for a long press for 3 seconds and wait for the lights to be turned off). After a while, I wanted to turn it on. At this time, I pressed the switch and there was no response at all. There was no light on and it turned black. Why is it? Is there something wrong with the miner that just arrived before it comes out, or is there something wrong with me in the process?
