Press and hold the charging base’s 【呼员/对冯】 key together with the sub‑phone’s 【转接/对码】 key for about 5 seconds; the base’s “使用中” indicator will flash and the sub‑phone will display “对码成功”.
Verify that the line connector is secure and not broken, ensure the sub‑phone or base has collected the line, and confirm the sub‑phone’s ringtone is not set to “off”.
The sub‑phone can store up to 60 incoming call records (30 missed and 30 answered).
