the selection you desired, just go around again (keep pressing any key) until the selection comes
around again.
This should make the programming much more intuitive. Once familiar with the Model 748's
operation, the manual may not be required to program the Model 748.
When programming the Model 748 with a modem, loss of carrier will force the Model 748 to exit
the programming mode and return to the normal operating mode.
CONVENIENCE FEATURES
As an aid to programming a Model 748, some convenience features have been added. Most apply to
programming of Users (which can be tedious).
Interconnect users:
You can block program many items in the User menu. Set the starting and stopping user number
with User range. When an item is selected for programming, you will be prompted to program all or
one at a time for the range selected.
You can advance to the next sequential user by typing
N
(for next) followed by
ENTER
. You can go
to the previous user by typing P (for previous) followed by ENTER .
You can search for a specific ANI in the user database. Select User range. When prompted for the
starting user, just press
ENTER . You will then be prompted for an ANI to search for. If found, it will
bring up that user in the menu. This can be useful for trying out Wild ANI!
Repeater Panel users:
You can block program many items in the User menu. Set the starting and stopping user number
with User range. When an item is selected for programming, you will be prompted to program all or
one at a time for the range selected.
You can advance to the next sequential user by typing N (for next) followed by ENTER . You can go
to the previous user by typing P (for previous) followed by ENTER .
CTCSS/DCS programming:
CTCSS tones are entered in Hertz. Just enter the first three digits of the tone. The Model 748 will
figure out the rest. See “CTCSS Tones” in Section 7 for a complete table of frequencies.
DCS codes are entered directly by prefacing the octal code with “D”. See “Digital Squelch Codes”
in Section 7 for a complete table of code supported.
To clear a CTCSS/DCS value, simply enter 0 for the tone/code.
QUICK EXAMPLES
Here are three quick examples of programming “Users” in order to demonstrate some basic
functions of the Model 748. A “User” may be defined as an individual radio operator who gains
access to the radio system by transmitting the appropriate DTMF codes, either manually, or by using
codes preprogrammed into particular radios' ANI encoders. We will set up one user (radio) for
interconnect only (Mobile-to-Phone, Phone-to-Mobile) using short sign-on, one user (radio) for
