------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Recording file format: MP3/WAV/WMA, Playback file format: MP3/WAV/WMA, Frequency response (L): 40Hz, Frequency response (H): 23000Hz, Sampling rate: 48kHz/16bit Memory capacity: 4GB, Compatible memory card: None Number of built-in microphones: 2, microphone movable: not supported, directivity switching: supported, external microphone: supported Low-cut filter: Supported, Noise cancellation: Supported, Automatic recording: Supported USB direct connection: Not supported, Type: AAA x 2, Drive time (recording): 51 hours, Drive time (playback): 58 hours
