If attempts to solve your problem fail, you
may be requested to return your instrument

return authorization (R.A.) number from your
authorized Penberthy distributor prior to

number collect the following information:

There will be a minimum charge applied for
evaluation of non-warranty units. You will be

charge will apply.
