functions of SAP on or off and setting the TV reception mode are not applicable for

the international version STI-TUNE.) The screen also shows the signal strength as a

percentage.

One of the features of the program is customizable presets, the name of the preset

and the station can be customized at runtime. The INITIALIZE ALL PRESETS

button sets all names (labels) to empty, and sets the station to 102.70 FM.

NOTE: It is often useful to put a known quantity into presets, otherwise whatever is

in system memory will be used which could provide undesirable results.

The tuning screen allows the station to be selected. The values of each station are

displayed with digital gauges. Note that VT Pro-e allows analog numbers to be

displayed with implied decimal points so that FM and WX stations may be formatted

properly. The stations can be tuned directly with the UP and DOWN BUTTONS.

The auto-repeat logic has been programmed in via the “button-repeater” modules.

A station frequency may be directly entered on the keypad. The display above the

keypad dynamically changes based on the type of station selected. For example, in

FM mode, the format will be displayed as XXX.XX. In AM Mode, it will be

displayed as XXXX. The station is entered by inputting a full number (such as 8950

for 89.50, 10270 for 102.70) and then pressing ENTER. The station values are

checked after pressing ENTER to be sure that they are within the proper ranges.

The preset recall screens show the 25 presets. When a preset is selected, it is recalled

to the ST-TUNE.

The setup preset screen allows the user to customize the presets. The user can enter a

name and the station number. The BAND is retained, Station is retained, and TV

Mode is retained. When recalled, Band, Station, and TV Mode (not applicable for the

international version STI-TUNE) are set up. This allows a preset to be completely

customizable, unlike most radios where there are banks of FM Presets and AM

Presets. The touchpanel contains on-screen help. The Crestron module “Text Entry

for 25 Fields” was used to program the preset names.
