This is the TEA-041 recording adapter for telephone handsets made by ELPA. It's an adapter that connects a telephone handset to a recording device to record conversations. After purchase, it was stored unused as I no longer needed it. Although the box and instruction manual are not included, the main unit is in new condition. Recommended for business use, crime prevention, and saving call records. 【Main Features】 • Handset recording adapter • Compatible with 4-pole 4-conductor modular jack • φ3.5mm mini-plug • Allows connection of phone calls to a recording device • Manufacturer: ELPA ※ Please check compatibility and connection methods in advance. ※ Please refrain from purchasing if you are concerned about minor details due to home storage. #ELPA #ELPA #RecordingAdapter #PhoneRecording #ForHandset #TEA041 #CrimePrevention #BusinessSupplies #CallRecording #UnusedItem
