Options. The Options Menu is a series of linked menu functions used initially to set your preferences. Once your preferences are selected, it is unlikely these functions need to be accessed during the normal operation of the product.

Contrast. The Contrast function allows the user to control the level of contrast of the LCD display. The 450TX will automatically adjust the display contrast to compensate for changing ambient temperatures; however, some situations may occur where manual adjustment will provide a higher level of contrast.

Eleven contrast settings, +5 to -5, are possible. The display contrast will change as the adjustment is made

so the optimum level of contrast can easily be

adjusted. Use the ARROW buttons to highlight the desired selection.
