When the menu mode is used, the <F1> and <F2> buttons become dedicated menu mode 
control switches (see following illustration). The <F1> button is Back/Clear, and the

programmed for other functions.

Menu Mode Buttons

Only the enabled menu items which apply to the selected channel type are displayed. For 
example, if a conventional channel is selected, only the enabled functions for conventional 
channels are displayed.

When in the menu mode, messages continue to be received on the selected channel. 
However, the display does not indicate who is calling. Pressing the PTT switch exits the 
menu mode and keys the transmitter.

The menu mode operates as follows:

1 To select the menu mode, press the <F2> button. Up to three menu parameters are then 

displayed as shown in the preceding illustration.

2 To scroll up or down through the menu parameter list, press the Up/Down buttons. The 

selected parameter is indicated by a dark bar.

3 To display the available modes for a highlighted parameter, press the <F2> button. The 

currently selected mode is indicated by an asterisk.

4 Press the Up/Down buttons to highlight the desired mode. Then press the <F2> button 

to select that mode.

5 To step back to the previous level or exit the menu mode, press the <F1> (Back) 

button.
