When you select Menu | Pswd Settings | IP Communications, the display shows the parameters

This example shows eleven rows, though in practice the display can show only three rows at
once. Use the Up and Down keys to scroll through the various settings. Press the OK button to
select a parameter.
Type the new value using the keypad. Most parameters require an IP address. To enter the period

the procedure described in section 6.2.5 on page 49.
Press the OK button (to save changes) or the Esc button (to discard changes) to exit the screen.
