Identify the exact equipment
Request the manufacturer, model, revision and relevant manuals. Confirm which accessories, software and support are included. Similar appearances can hide different configurations.
Check site requirements
Review electrical supply, grounding, network needs, ventilation, noise and the load placed on the floor. Use the supplier’s documentation and a qualified installer where needed.
Separate claims from evidence
Ask for applicable documents, content licenses and operating restrictions. Confirm price, condition, lead time, warranty scope and support terms in writing before committing.
