I don't know if this will help, but this is the procedure for two different brands of wireless mouse and keyboard that I have used.
1. Identify reset button on underside of receiver
2. Identify reset button on underside of mouse or keyboard.
3. Press & hold for 1 or 2 seconds reset button on underside of receiver (may need paper clip or point of pencil)
4. Press & hold for 1 or 2 seconds reset button on underside of mouse or keyboard (may need paper clip or point of pencil)
You may see an LED light on the receiver go from flashing to steady or vice versa or change flash rate as you do these steps.
This seems to be pretty generic because here is a web guide I found
