Video: How can I be sure that the 2W IR laser module has been installed successfully?

Please check the following to determine if the 2W IR laser module has been successfully installed after following the video or user manual?

After turning on the machine, the fan on top of the laser module will spin at high speed for a few seconds.
Then you will hear two beeps, and the fan will switch to a steady rotation.
Looking inside through the top fan from directly above the laser module, you can see a green light constantly on in the upper right corner.
After the beeping sound, the laser module will move to the standby position at the back left.
A red dot can be seen directly below the laser head.
