Note:
Several of the Main Menu settings are also available via direct access function keys located to the left of the
numeric keypad. These include Frequency (‘Freq’), Mode, and Bit Rate (‘Rate’). The front panel keypad is shown in
Figure 19. Depending on the number of options provided with the RDMS™, some menu items may not display
when the RDMS™ is powered on. To see additional LCD menu options, use the arrow keys to scroll up or down.
The complete list redisplays continuously forward or backward, depending on which arrow key is pressed.

To change a setting or access a secondary menu, use the arrow keys to navigate to the parameter. Once highlighted,
the Enter key prompts a secondary menu screen or a setting screen, or even change the setting itself if there are only
two possible states. To back out of a sub-menu, press the Escape key, ‘Esc’ on the front keypad.

There are two methods available to the user to set the receiver’s frequency. The first one is to press the Freq key on
