Checklist before sale or long-term storage

Before selling or storing an item for a long period:

• perform a functional check;
• clean it without hiding defects;
• photograph condition and serial number;
• record modifications, repairs and maintenance;
• check batteries and power;
• gather original parts and accessories;
• inspect the case and contact materials;
• avoid unnecessary last-minute cosmetic work.

For a sale, this documentation supports a more accurate description. For storage, it creates a baseline against which the item can be compared when it returns to use.
