First time setup:
Factory default brightness setting is very dim, so you have to set it up yourself upon turning it on. The top circle button is to switch between visible LED and IR mode. With IR mode, the reticle is visible under night vision goggles. Circle button is not meant to turn off the device.

To toggle brightness, it would be the bottom two rectangular buttons. [^] for brightness up, and [v] for brightness down.
Pressing both buttons at the same time turns off the device.
For first time setup, press [^] button three times. Then press IR button once. Then press [^] button three time again. Then press IR button once. Repeat process until red LED reticle is visible. After you turn off the device, it will remember its brightness position.
