APPLICATION PRESETS (M1)

The Application Presets screen allows the user to quickly and easily configure the T35 for common applica-

tions. In some cases, the Application Presets will be the only setup needed for properly configuring the T35

transmitter.

There are three Application Presets to choose from:

Hearing Assist, Music and Voice. When one of these

selections is “set,” the performance of the T35 is immediately optimized for the needs of that application (an

adjustment is automatically made to the Low/High Pass Filter, and Compressor Slope controls). Refer to the

chart below for a comparison of the Application Preset configurations.

By default, the T35 is shipped

in the Music mode. For music, concerts, and other applications where the

highest audio quality is desirable,

Music is the recommended mode of operation. For hearing assistance

applications, or applications where the message is critical for listening,

Hearing Assist is the recommended

mode of operation. For speaking and other voice applications,

Voice is the preferred mode of operation.

To select an Application Preset:

1) Press the “ ” menu button (Figure 12) to access the LCD

“Application Presets” screen (M1).

2) Press the “+” or “-” menu buttons to select between

Hearing Assist, Music and Voice.

3) When the desired Application Preset is displayed, press the “Set” button to

save the change into memory.

No additional action is necessary. After 30 seconds of inactivity, the LCD screen

will return to the default screen, where the selected Application Preset will be

displayed. NOTE: After an Application Preset has been selected, any of the

configurations can manually be changed if necessary.

The Application Presets are designed to take the guess work out of common setup procedures.

There will be times when manual adjustments will need to be made (i.e. to select a dif

ferent operat

ing frequency

, bandwidth, to adjust the compression ratio, etc.). For these requirements, please read

through the manual and follow the corresponding menu control instructions. If you are unsure of

how these changes will impact the performance of the T35 transmitter, or how it will affect your

hearing assistance application, please contact Williams Sound for assistance at 800-843-3544.
