A:AnswerI haven't tried it with the same manufacturer keyboard/mouse, but it does work with two different ones. I use my Dynex brand and a Microsoft brand frequently at the same time. I have never seen any indication of cross-signaling.
A:AnswerNot for the Caps Lock button. It has LED indicators to let you know the status of the battery at a glance and keep you apprised of wireless pairing.
A:AnswerWireless transmitters are usually only available with the unit at point of sale. I would recommend getting another wireless keyboard/mouse combo setup. Logitech offers Unifying keyboards and mice. That means if it's a Unifying product, the receiver can be programmed to the device (s).
A:AnswerThis keyboard/mouse combo is wireless, but still requires a USB port to install the dongle. If you're looking for an iPad compatible keyboard, you might try researching Bluetooth keyboards instead.
