Status Lights
The red status lights next to the line keys show what is happening on
those lines.
A line key status light may turn on steadily, blink, or flash at different
rates to signal the status of that line.
Speaker
The Optiset E Basic and Advance telephones have a speaker
underneath the handset that can be used for receiving calls or listening
to the PhoneMail system. Since the speaker is one-way, the user must
pick up the handset to speak to the other party. For more information,
see “Using the Speaker” on page 3-9.
Speakerphone
The Optiset E Standard and Advance Plus telephones have a two-way,
half duplex speakerphone, consisting of a speaker and a microphone.
The Optiset E Advance Conference has a full duplex speakerphone,
consisting of a speaker and a microphone. Either the handset or the
speakerphone can be used to make or receive calls.
During a conversation, the speakerphone can be used instead of the
handset by pressing the Speaker key and hanging up the handset. To
switch back to the handset, the user can pick it up again. For more
information, see “Using the Speakerphone” on page 3-10.
