Sanwa Supply Spreadsheet Bluetooth Numeric Keypad NT-BT27BK

【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. This spreadsheet numeric keypad features keys optimized for Excel. In addition to the keys found on a standard numeric keypad, we have added the following: "ESC", "F2", "F4", "Half-width/Full-width", "Alt", "Ctrl", "Shift", "Tab", "Copy", "Paste", "Search", "(", ")", "=", and ",". This is a Bluetooth numeric keypad compatible with Bluetooth 5.0. It can connect to Bluetooth-enabled devices without a receiver. If your computer has built-in Bluetooth, you can use it without blocking the USB port. Featuring silent keys, this keyboard is ideal for quiet offices and other places where typing noise is a concern.
