------------------------------------------------------------------------------------------------------------------ 【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: WMA Memory capacity: 1GB, Compatible memory card: None Number of built-in microphones: 2, microphone movable: not supported, directivity switching: not supported, external microphone: supported Low-cut filter: Supported, Noise cancellation: Not supported, Automatic recording: Not supported USB direct connection: Supported, Type: AAA x 1, Drive time (recording): 15.5 hours, Drive time (playback): 26 hours
