That is, the error is displayed without a network cable connected? This is one of the few reasons: the built-in LAN connection is dropped. The memory module (if any) is defective. Or the whole trainer is faulty.
You can try turning it off and resetting NVRAM (Google only) to see if that helps. If the device was accidentally involved in programming, this will be corrected.

When you’re done with 3015, you can spend almost as much as you would on a new 402 (it only costs about $ 200). Throw in a couple of visits to a tech company and you can spend up to $ 506.
