125R.. Many moons ago I had a hearing problem so they said I needed an audiogram every few months. Later, I attended an ENT clinic with sinus probs and they ran a hearing test. They said it was the best they'd seen for ages so I put this to (what we now know as) SRG and they lifted the restriction with apologies. Give it a whirl; they're only human and may not have intended you to be restricted so long.. GL.
