What information must be provided to Yamaha tech support when they answer the phone?

When contacting Yamaha tech support, providing the PID (Product Identification Number), dealer number, and technician name is essential. The PID is crucial because it uniquely identifies the product and allows Yamaha to access specific information related to that unit, including warranty status, service records, and technical bulletins relevant to the inquiry. The dealer number ensures that the support team knows which dealership is seeking assistance, while the technician's name helps establish a direct line of communication, ensuring the tech support can address inquiries efficiently and accurately.

This set of information aids Yamaha in verifying the caller's identity and purpose, streamlining the support process, and ensuring that the guidance provided is pertinent to the specific product in question. The other options do not encompass all the necessary identifiers used by Yamaha tech support to assist effectively in technical matters.
