• Part Refurbishment: Technicians re-solder damaged connections, change malfunctioning microswitches, or repair damaged transponder coils.
• Shell Replacement: Because the initial casing needs to be cut open, technicians usually house the fixed circuit board inside a brand-new, pristine plastic shell.
