After running the demo, the first screen is the Welcome Screen. The Welcome Screen is shown for up to 1.5 sec-

The on-screen menu system is designed for easy configuration. The RF and packet parameters of the
communication can be configured as described in the previous sections.
Four push buttons are used to navigate the menu system: soft labels on the LCD screen display the current
function of the related buttons. In general, push button 1 (PB1) is used to go to the previous menu page; push
button 2 (PB2) is used to select between menu items, push button 3 (PB3) is used to change value of the menu
item, and push button 4 (PB4) is used to access the next menu page. Some of the menu items have more than ten
possible values. In such cases, not only PB3 can be used to increase the value of the menu item, but PB2 and PB3
can be used together to decrease its value. To decrease such values, push and hold PB2 and then push PB3
several times to reach the required value.
A small arrow (  ) points to the actual menu item. The demo can be configured through six menu pages.
The first page is used to select the functionality of the demo. The range test can be performed in single way (Tx—
transmit or Rx—receive mode) or bidirectional (TRx—transceiver mode) radio communication. If custom RF
parameters are stored, the user can choose between “Custom” or “Select” RF parameters. If “Custom” RF
parameters is selected, the user can only check but not change the RF parameters on the following menu pages.
