Record sample identifiers, software versions, accessories and operating instructions to make testing preparation and sample handover clearer.

Before submitting samples, assign each unit a unique identifier and record its model, hardware version, software version and external condition. Use the same identifier on the sample, packaging label and handover form so the exact device and configuration can be traced later.

List power adapters, cables, loads, charging docks, remote controllers and other associated items individually, including quantities and purposes. If dedicated software, accounts or test tools are required, agree on a delivery method with the project contact and include repeatable operating instructions.

Record unresolved issues and temporary modifications in the handover documentation. When additional information or sample adjustments are requested, keep update dates and change records to maintain a shared understanding of the submission status.
