The
Selecting a Feature
A unique feature of the MTX Series radio is its use of the display to give you quick access to many of the radio’s features without requiring a dedicated mechanical key for each feature.
After pressing either of the two arrow keys, the names of the features (PAGE, CALL, MUTE, etc.) are shown on the display, three at a time, with
Selection of features is controlled by the three keys directly below the feature names shown on the display: the left key selects the left feature, the middle key selects the middle feature, and the right key selects the right feature.
Left and Right Arrow Keys
The left ( 
) and right ( 
) arrow keys are used to scroll the display forward or backward through the radio’s features and lists. There is no end point to the list, so if you continue to scroll in one direction, the display will “wrap around” back to the beginning of the list. If you hold either key down, the display will scroll at a faster rate until the key is released.
The left arrow key is also used for editing when you are entering information manually from the keypad. Pressing the left arrow key will backspace, and erase the display, one character at a time. If you have erased all the digits, an additional press of the left arrow key will return the display back to the preprogrammed list.
HOME Key
The HOME key will always return you to the home display. This is the current system/mode. In addition, if you are using a feature that requires it, pressing the HOME key will also cause information to be saved in the radio’s memory before going to the home display. Some radio features will automatically go to the home display when they are completed, without having to press the HOME key, thus reducing the number of keypresses required.
