Frequently Asked Questions
Does the Kensington Pro Fit Ergo combo work over Bluetooth or only with a USB receiver?
Both. It supports a 2.4 GHz wireless receiver and Bluetooth 4.0 LE, and a three-mode switch toggles between 2.4 GHz, Bluetooth, and off.
Is the wireless connection secure enough for office use?
Kensington says both connection modes use 128-bit AES encryption, which it describes as government-grade.
What happens if I lose the USB receiver?
The receiver can be replaced. You buy a new one and pair it with the keyboard and mouse, so you don't have to replace the whole combo.
Is the keyboard loud to type on?
No. The listing describes the keys as quiet clicking, and they are also spill-proof. That makes the combo a good fit for shared offices or late-night work.
