How to use the navigation keys 21

Contrast and brightness

Use the Contrast and Brightness option to adjust these levels of the display, and to reset the sleep timer. To extend the life of the touch panel display, the IP Phone uses a sleep timer, which turns off the backlight when the preset time elapses.

See “Adjusting the contrast and brightness of the display” (page 53) and “Adjusting the sleep timer” (page 89).

USB devices

Use the USB Devices option to view information about the device connected to the USB port.

USB devices are not supported in release (I)SN09FF.

TFTP upgrade

Use the TFTP option to upgrade the firmware. This tool is used by administrators only.

See “Performing a firmware upgrade” (page 75).

Preferences

Use the Preferences option to access the Button Customizing Tool. Use the Button Customizing Tool to change the look of the dedicated feature keys.

See “Using the Preferences tool” (page 91).

How to use the navigation keys

The IP Phone terminal has four keys that you use to navigate the menus, and to help you to enter text in the display. See Figure 1 "IP Phone 2007 components" (page 9) for the location of these keys.

When the menu system is active, the navigation keys behave this way:

•up key—return to the previous menu item

•down key—got to the next menu item

•left/right key—active when you can enter text. To move the cursor to the left, press the left key. Press the right key to move the cursor to the right.

After you select an option, you can press Ok on the touch screen to execute the selection.
