Thank you for viewing. This is an Olympus IC voice recorder. It was used for about six months. The rechargeable battery that came with it when it was new has been lost, so it has been confirmed to be working with alkaline batteries installed. The box, USB cable, and instruction manual are all included. It is also listed on other sites, so please forgive me if it sells out (it's best to let me know in the comments before you buy). * Omnidirectional stereo microphone and "scratch noise filter" that allow for clear recording even when placed in a pocket. * One-touch recording and self-timer function for smart operability. * Microphone/earphone combo jack and USB port to broaden the range of usage styles. * Date search function that makes it easy to find the desired file from the recorded date. * "Voice Chaser" Automatically adjusts the recording level to the optimal volume according to the volume of the sound, which varies depending on the size of the room and the number of speakers. * "Voice Balancer" Plays back all recorded audio at an easy-to-hear volume, amplifying small sounds and preventing large sounds from exceeding a certain level. * "Transcription Mode" This mode is convenient for transcribing recorded data. When resuming playback after an interruption, it automatically rewinds 3 seconds from the point of resumption to prevent the beginning of the audio from being cut off. In addition, silent parts can be skipped at 2x speed, increasing the efficiency of transcription work. When this mode is selected, "Voice Balancer" is enabled. * Noise cancellation function Reduces background noise that has been recorded and plays back the audio clearly.
