Press and hold the base’s “呼员/对冯” key and the sub‑phone’s “转接/对码” key together for about 5 seconds; the base indicator flashes and the sub‑phone shows “对码成功”.
Check the external line connection, ensure the base has collected the line, and verify that the sub‑phone’s ringtone is not set to “off”.
Remove the battery, wait ten seconds, then re‑insert it; the sub‑phone will restart and regain functionality.
