  1. Mouse is out of/on the boundary of its range.
  2. Mouse is connected to the PS/2 port.
  3. Mouse is placed too near to the receiver.
  4. The mouse needs to be re-installed.
Explanation
Answer: A - Mouse may be out of/on the range of its operation. Read the manual that came with the mouse and keep the mouse within the operating range.

Key Takeaway: Wireless input devices generally operate using RF signals. The prime requisites for a wireless mouse to work efficiently are optimal range and batteries. The mouse should always be within the range of the transceiver. The batteries used in the mouse and the receiver should be charged. If these conditions are not met, the mouse starts working erraticallyor does not work at all.
