FCC 15.31 (e) This test was performed with the New Battery (DC 3.0V) and the constant voltage was supplied to the EUT during the tests. Therefore, the EUT complies with the requirement. FCC Part 15.203 Antenna requirement It is impossible for end users to replace the antenna, because the antenna is mounted inside of the EUT. Therefore, the equi…
