Hello! Our practice recently purchased this instrument from another practice and were wondering where we might be able to get some additional training about how to best incorporate this instrument into our practice. We're especially interested in how to integrate the wellness screening in particular. Is there a way to set up a meeting with a technician whether in person/virtually? Thank you for your input.

The context does not provide information on training resources for integrating wellness screening or how to set up a meeting with a technician. It only advises consulting the dealer from whom the instrument was purchased for additional questions.
