Configuration menu mode
When user preferences are being configured in the Config menu, the
handset is on, but is not active. It cannot receive calls while in the
Config menu. The handset will revert to standby mode if there is no
activity in configuration menu mode.
Message alert mode
If text messaging functions have been programmed, as in a nurse call
system, the handset is able to receive text messages. While these
messages are being accessed, the handset is in message alert mode.
Incoming calls will ring with the second call ringing sound.
