1.2 Overview
This user’s guide covers five different telephone models. The overall
operation of each telephone is very similar, but there are several
differences between the telephones:
•
The 8112N and 8212N do not have speakerphone capability.
Therefore, you must lift the handset to perform any telephone
functions (making calls, answering calls, programming your
telephone, etc.).
•
The 8112N and 8212N telephones cannot use the Group Listen
feature.
•
The 8112N and 8212N telephones cannot use the Background Music
feature.
•
The 8112N does not have any LEDs beside its programmable
buttons and, therefore, does not provide status indications for these
buttons.
•
The 8112N does not have a MUTE key.
•
The 8112N does not have a handset volume control.
•
The IMIST module will only work with the 8212S and 8212N
telephones.
•
The 8124S and 8112S telephones have a rocker-switch style volume
control instead of separate VOLUME UP and VOLUME DOWN
buttons.
•
Message waiting lights:
– on the 8124S and 8112S telephones, the message waiting light is
above the HOLD button,
–
on the 8112N, the message waiting light is above the numeric
keypad,
–
on the 8212S and 8212N, there is a dedicated message button with
an associated light beside it.
•
Only the 8212S and 8212N support the ICVOL handset with
independent volume control.
