The HB1132 is a universal DVD machine remote‑control IC that integrates a high‑power transmitting tube, eliminating the need for external transmitting transistors, reset circuits, and many passive components. It supports features such as brand pass‑through, direct code entry, semi‑automatic and full‑automatic search, child lock, and a built‑in self‑test mode.
The manual describes how to input codes directly, set up brand‑specific keys, perform automatic searches, enable the child lock, and run the production self‑test. A circuit diagram and pin‑binding table are also included for hardware reference. This manual is written in Chinese.
