The Air 2 and it's hand controller have been ignored for 3 months.  Now I'm trying to fire them up again.  First I fully charged the batteries.  Then I pressed and held the battery button on the Air 2 and, after showing the battery charge state for a few seconds, nothing happened.  It used to make internal-fan noise and twitch the props when I did that, but this time nothing.  I recon I'm doing something stupid, but can somebody please tell me what I'm doing wrong? -- jclarkw

Hello there jclarkw. I am sorry for the trouble this has caused and thank you for reaching out. As posted above kindly please try to power on the said DJI remote controller once again by pressing the power button once , then press again, and hold for two seconds to turn the said DJI remote controller on or off. Thank you.

Don't worry about it. That is me every Monday morning before work. Never can remember to hold that start button.
