Push-to-talk (PTT) mode
The SpectraLink 8030 Wireless Telephones utilize channels for
incoming and outgoing radio communication. While PTT is active, the
handset is in PTT mode. It can receive regular phone calls in this
mode. When a regular phone call is answered, the handset enters
active mode.
Configuration menu mode
When user preferences are being configured in the Config menu, the
handset is on but is not active. If the handset is idle 20 seconds while
in the Config menu, it will return to the standby state. Calls can be
received but cannot be answered unless you exit the Config menu. If a
call was trying to be established while in the Config menu, it will ring
as soon as it returns to the standby state.
Messaging 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 messaging mode.
Incoming calls will ring with the second call ringing sound.
