● No optical light visible on the MK270 mouse
Your mouse uses an infrared (IR) optical LED light that is
invisible to the human eye. This means you won't be able
to see the light emitting from the bottom of your mouse.
If you're not sure whether your mouse is powered on,
check the ON/OFF switch located on the bottom.
NOTE: The M185 mouse is included in the Wireless Combo
MK270.

ON — The switch is pushed over to the right and you see
green next to it.

red next to it.
