If the charging indicator is not displayed or disappears while charging your Sony Voice Recorder, ensure you have inserted rechargeable batteries correctly. Verify the battery orientation and use only NH-AAA rechargeable batteries. Replace old batteries if they have deteriorated. Reconnect the USB cable properly. If “USB??” is set to “?” in the menu, change it to “?”. Stop any playback or radio before charging.
