Hi and welcome to JustAnswer,

The only easy doable try of a fix for the described intermittent problem with a VeriFone Vx510 Credit Card Terminal is to very carefully clean the contacts (inside the port of the terminal) with foam swab dipped in LPS Electro or DEOXIT D5 Contact Cleaner. In some instances, it may even be necessary to clean hard to expose fresh metal or slightly bend the contacts so as to offer more contact pressure with the RJ11 connector of the telephone wire. In some others, it maybe a physical fault with the locking tab. Ensure that the RJ11 connector plugs in with a clicking sound that signifies it is locked in place.

All others would require opening the unit to check for loose connection or more particularly cold solder.

Good luck and thank you for asking JustAnswer.
