from the mouse case
• After finishing work you can pull out the receiver from the PC USB port
and insert it into the mouse (Fig. 6).
When using the receiver again, pull it
out from the mouse (Fig. 7) and connect it to the PC USB port again.
• Do not place the receiver into a confined metal space (table drawer, box,
safe), as a metal screen does not transmit radio signals.
• If the battery run down, the mouse works in jerks. It means that the battery should be replaced with new ones, as it is shown in Fig. 4. Always install only identical new battery.
