A restaurant chains client in North Sichuan Road had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.

The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.

The client moved into a new office in North Sichuan Road, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
