2.1 FRONT PANEL CONTROLS
NOTE: The location of these controls is shown in
Figure 2-1.
Microphone - The microphone is located behind the
small opening shown in Figure 2-1. For best results,
hold the radio 2-3 inches from you mouth and speak at
a normal conversational level. Do not shout since it
distorts your voice and does not increase range.
Display - This is a graphical LCD (Liquid Crystal
Display). The display backlight can be programmed to
turn on when any key is pressed or when the Backlight
option switch is pressed or menu parameter selected
(see Section 3.5).
Up/Down Switch - Selects zones when multiple zones
are programmed (see Section 3.3). Pressing the upper
part of the switch selects the next higher number and
pressing the lower part selects the next lower number.
This control also provides up/down select in the menu
mode and in other modes when up/down select is
required.
F1 - In menu mode (see Section 4.2), functions as a
step back and exit switch. If menu mode is not used, it
is a programmable option switch.
F2 - Selects the menu mode when that mode is
enabled by programming. Also functions as an Enter
or Select switch in the menu and other modes. If menu
mode is not used, it is a programmable option switch.
F3, F4 - Programmable option switches.
