Your Forum Phone 510 has a two-line display, a numeric keypad,
several function keys and four menu control keys. All Forum Phone
510 and ISDN functions and features are controlled using these
menu keys, which are explained in the section entitled Menu Con-
trol starting on page 5. The remaining keys on your Forum Phone
510 have fixed functions. The
±
and
‘
keys serve as digit keys.
The display on your Forum Phone 510 shows digits, e.g. telephone
numbers or the current time, as well as messages, texts and the
menus with the functions of your terminal. Certain states, e.g.
active call forwarding, are displayed here. The accrued connection
charges are also shown in the display, providing the call connec-
tion display is active. The displays in the lower display line
change: during a call the softkeys have a different function to that
in idle state. If your terminal displays a message (e.g. an error
message), the menu display (key functions) is overlaid for about 2
seconds with the warning text. The message then disappears and
the softkey functions are displayed again.
