Cables were attached to each of the available I/O Ports. Where applicable, peripherals were attached to the I/O cables. All the external I/O ports are exercised, as well as internal and the external SD card, by writing and reading arbitrary data or charging with TA. The EUT was investigated in three orientations and the worst case orientation is reported. Cellular Rx mode conducted testing was performed with the LTE FDD 5 mode at center frequency. All licensed communication Cellular Rx mode, WCDMA/LTE/5G tes t results are not significantly different. Audio and video were played on monitor through Display Out function using direct DP Cable or DP converter. The camera of the EUT was operated continuously. Power source for the EUT operating was supplied by CVCF made by Digitek Power and AC Power Korea.
