I have the PDQ 4000's with VT and would like to know if there is a manual for VT calibrations? We have the older sonics (large blue) and can no longer buy them according to our distributor. Not sure if we have a bad sonic or if it just needs to be calibrated more often. They want alot to change one bay over to the new sonics. Any suggestions would be apprciated.
Thanks,
Paul
