Radio do not helicopter battery life

[Zentiger]

Hello,
I just bought a flying FW450 and my radio doesn’t show the helicopter battery life
it shows the TX and the battery figure but, below shows kind of antenna
did any one has the same problem?

Does it look like this?


That's not a kind of "antenna". It's a question mark. (?)

It'll look like this after you plug the battery in:

Hello
sorry, I was in business travel
I added a photo showing the antenna

I've never seen that on mine. I think it means that the RX is not communicating with the TX. That's why there is no battery information. Take off the canopy and look at the RX and see that the cable is plugged into the proper port on the flight controller. Also make sure the RX antenna is not broken or damaged.
