Radio-Wide Features; Option Switches; Menu Mode; Time-Out Timer - E.F. Johnson Company 4100 SERIES Operating Manual

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.
