Front Panel Controls and Functions

IFBT4 VHF Front Panel
OFF/TUNE/XMIT Switch
OFF Turns the unit off.
TUNE Allows all functions of the transmitter to be set up, without transmitting.
The operating frequency may be selected only in this mode.
XMIT Normal operating position. The operating frequency may not be
changed in this mode, though other settings may be changed, as long
as the unit isn't "Locked."

Power Up Sequence

When power is first turned on, the front panel LCD display steps through the
following sequence.
1. Displays Model number (e.g. IFBT4 VHF).
2. Displays installed firmware version number (e.g. V1.00).
3. Displays the current compatibility mode setting (e.g. COMPAT IFB).
4. Displays the Main Window.

Main Window

The Main window is dominated by an audio level meter,
which displays the current audio modulation level in real
time. In TUNE mode, a blinking capital "T" is displayed
in the lower left corner to remind the user that the unit is
not yet transmitting. In XMIT mode, the blinking "T" is
replaced by an antenna icon.
Audio limiting is indicated when the audio bargraph
extends all the way to the right and widens some-
what.
The Up and Down buttons are disabled in this Win-
dow, but they will display voltage (e.g. 15.4 VOLTS).
