Function Keys

Function keys are softkeys on the touchscreen display. The func-

tions of these keys are configured and labelled with the

Forum 500 / Forum 5000 communications system. These keys

offer access to individually configurable system functions such as

e.g. configuring call forwarding, executing speed dialling, display-

ing a busy lamp field or accessing the phone book of the commu-

nications system.

Depending on the function programmed the respective state is

signalled via the softkey lighting up red or blinking red (please

refer to the chapter Programming Function Keys starting on

page 49).
