so if some fields are unprogrammed or improperly
programmed, an error message is displayed. Refer to
Section 4.5.6 for more information.
4.5 MAIN MENU
4.5.1 INTRODUCTION
The Main Menu screen shown in Figure 4-2
appears when the program is started. This screen is
used to select the function to be performed. It deter-
mines if a new configuration file is to be created, an
old file edited, or the current file is to be printed, saved
or downloaded to a radio. It is also used to upload a
file from a radio, and to copy, rename, or delete a disk
file. The functions that can be selected in this screen
are described in the following information.
The following function keys perform special
functions in this menu. Other function keys active in
this menu are described in the preceding section.
F5 (Change Dir) - Displays the screen that changes
the current directory. When a configuration file is
loaded from or saved to disk, it is always from or to
the current directory. Therefore, if you need to change
this directory, select this screen.
F6 (Show Files) - Displays the names of all radio
configuration files that are in the current directory.
F7 (Warranty Info) - Displays the following screen
which indicates the transceiver identification number
described in Section 1.4. This number is stored in
memory on the audio/logic board and cannot be
changed. The “RF Power” parameter in this screen is
the same as the “Type” number described in
Section 1.4.
4.5.2 SET UP NEW CONFIGURATION FILE
This function is used to create a new configura-
tion file. The type of radio is selected by specifying
the following information. After this configuration
information is selected, the Modify Radio File menu
described in Section 4.6 is displayed.
Radio Band - 400, 800, or 900 MHz
Radio Range - 430-470 or 470-512 MHz
Radio Type - Low, Mid, or High Tier LTR
Low or High Tier LTR-Net upgradable
High Tier Multi-Net®
LTR or Multi-Net Data
IF Bandwidth - Dual (25 and 12.5 kHz),
Narrowband (12.5 kHz only)
The frequency range is displayed only with 400
MHz models because 800 and 900 MHz models are
full band. Also, the IF bandwidth screen is not
displayed with 900 MHz models because they are
always narrow band. LTR transceivers which are LTR-
Net upgradable have a “6” as the fifth digit of the part
number (see next paragraph). The LTR-Net type must
then be chosen to prevent a type error from occurring
when the transceiver is programmed. LTR-Net opera-
tion is not actually programmed by this software.
The preceding information can be derived from
the screen that is displayed by the F7 key (see Section
4.5.1). In addition, with high tier models, it can be
derived from the transceiver part number that is briefly
displayed when power is turned on (see Section 3.4.1).
Refer to Sections 1.3 and 1.4 for more information on
warranty and part numbers.
The radio type specified for a file can be changed
using the Change Model/Band/Range/Tier parameter
as described in Section 4.6.9. This allows, for
example, one file to be used as a basis for program-
ming another. This eliminates the need to re-enter
some information when programming a similar
transceiver.
4.5.3 OPEN CONFIGURATION FILE
This function is selected to open a configuration
file stored on disk and load it into the computer
memory. The files in the current directory are
displayed and then the arrow and Return keys are used
