RADIO-WIDE FEATURES
SECTION 4   RADIO-WIDE FEATURES
4.1 OPTION SWITCHES
NOTE: For descriptions of the functions controlled by 
these switches, refer to the section of this manual 
referenced in the last column of Table 4-1.
Almost all the buttons on this radio are 
programmable as follows:
On the side panel, the three buttons above the PTT 
switch (see Figure 2-3 on page 11).
On the top panel, the rotary three-position switch 
and the orange button (see Figure 2-2 on page 11).
On the front panel, F1 and F2 unless the menu mode 
is used (see next section), and F3 and F4.
With DTMF keypad models, all 12 DTMF keys.
The functions that can be controlled by option 
switches are shown in Table 4-1. Each option switch 
can be programmed to control a different function in 
each of the three operating modes. For example, F3 
can control one function when a conventional channel 
is selected, another when a SMARTNET/SmartZone 
channel is selected, and still another when a Project 25 
trunked channel is selected. 
4.2 MENU MODE
NOTE: For descriptions of the functions controlled by 
the menu mode parameters, refer to the section of this 
manual referenced in the last column of Table 4-1.
Most functions that can be controlled by an 
option switch can also be controlled by the menu 
mode. The functions that can be controlled by the 
menu mode are shown in Table 4-1. Functions can be 
controlled by both an option switch and a menu 
parameter if desired.
When the menu mode is used, the F1 and F2 
switches become dedicated menu mode control 
switches (see following illustration). The F1 switch is 
Back/Clear, and the F2 switch is Menu Select/Enter. If 
the menu mode is disabled, these switches can be 
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 key. 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 switch. The selected 
parameter is indicated by a dark bar.
3. To display the available modes for a highlighted 
parameter, press the F2 switch. The currently 
selected mode is indicated by an asterisk.
4. Press the Up/Down switch to highlight the desired 
mode. Then press the F2 key to select that mode.
5. To step back to the previous level or exit the menu 
mode, press the F1 (Back) key.
4.3 TIME-OUT TIMER
The time-out timer disables the transmitter if it is 
keyed continuously for longer than the programmed
