## S4-260586: Clarifications to Scenario 3 Database for Device Type 3

**Source:** Beijing Xiaomi Mobile Software Co., Ltd
**Meeting:** SA4 #135-bis-e, April 2026

- **Context:** Follow-up contribution providing clarifications to the DaCAS recordings database (DaCAS-1), as requested in previous SA4 meetings.

- **Recording setup clarifications for source distance:**
  - Hand-held and headset devices: source at **1.0 m**
  - Table-mounted devices: source at **height 40 cm above table**, **80 cm in front** of the geometric center of the UE, screen face up, azimuth 0° pointing to long edge with bottom

- **File naming correction:** Table-mounted recording filenames are updated to reflect correct elevation angle, e.g., `D03_S03_Table-mounted_26.6deg_*`

- **Updated database:** Revised "DaCAS recordings database.xlsx" attachment provided with a new download link (password-protected)

- **Proposal:** Agreement sought on the clarifications and the updated database attachment for DaCAS-1
