On a successful start-up, a lock screen with a 4 digits and instructions to control the HMI application is seen on the monitor (see Figure 11)

Within a maximum distance of about 40 cm from the mmWave EVM, move the palm of your hand in a right-to-left swiping motion or in an up-and-down swiping motion to interact with the GUI as described below.
Left-Swipe Gesture: Swing your hand from right to left in front of the mmWave sensor to move to the next digit, that is, change the active digit selection. Each right-to-left hand gesture moves the digit selection by 1 digit to the right (see Figure 12).
Figure 12. Left-Swipe Gesture
Down-Swipe Gesture: Swing your hand up and down in front of the mmWave sensor to change the value of the currently selected digit. The value of each digit cycles from 3 to 8. With each down-swipe hand gesture, the digit increases by 1 (see Figure 13).

The unlock code is 6843.
Use the left-swipe gesture to select the first digit from the left then, use the down-swipe gesture until the value of the digit changes to 6.
Use the left-swipe gesture to move the digit selection 1 digit to the right.
Repeat step 6 and step 7 to change the digit combination to 6 8 4 3 which is the unlock code.
With the digit pattern matching the unlock code, the unlock image should be seen on the monitor (see Figure 14).

If no motion is detected in front of the sensor for a few seconds, the screen turns to black indicating Idle mode.

When motion is detected, a lock along with keys to enter the 4 digit password is displayed back on the monitor.
