Each cuff has two distinct command words engraved on it in Taldane, one that locks and unlocks the cuff from the person wearing it, one that locks and unlocks from the chains that it attaches to.  The command words, obviously, only work for Keltham.

He'll first try out telling the cuff to lock to one of the nonmagical chains, pull on it to test that connection, then make sure it releases when he speaks the command word again.

He'll then clasp that cuff around her left wrist, tell it to lock, try to remove it by strength, test out unlocking and removing it by repeating the command word, and then re-bind it on Carissa's left wrist and leave it there.

Keltham doesn't speak himself; it doesn't feel necessary.  There's a strangely focused feeling to his thoughts - though not so focused that he's not checking all execution paths through his cuff-testing procedure, to make sure that no previously-untested malfunction during the tests themselves would allow Carissa to end up bound to the bed with no way to remove her.

One cuff down, three to go.
