nerf terrascout issues (drone not entering pairing mode)

So I bought a used Nerf TerraScout at a thrift store (I bought it for 15 dollars, absolute haul) and the TerraScout did not connect to the controller. I looked at the manual. it said that a flashing green light means that it is in pairing mode. the thing is, mine is just showing a solid green light for a few seconds and then turning off. any ideas on how to factory reset or otherwise fix this problem?
