Changes from Firmware Version 1.0 to 1.1
- Fixed an issue that resulted in the camera interfering with nearby radios and other devices, possibly producing audible noise, when connected to the EH-73P/EH-73PCH charging AC adapter via USB with the battery inserted and the power off. This issue does not occur when the EH-71P/EH-71PCH charging AC adapter is used.
