Interchange Audiometers and middle ear analyzer manual services

[juancaballerocordova]

I calibrate all kind of hearing audiometers and tympanometers, but i have other very old audiometers or tympanometers, and here in El Salvador people buy the audiometer without service manuals.

So Im looking forward find some service manuals, and if i have some service manual that you need i can send it to you.

Thank you
