a. CPM is Call Process Monitor which enables the user to hear, for example, the dial tone in the speaker. Group
listening enables the user to speak through the handset/headset microphone and one or more parties can lis-
ten through the speaker, thus hearing both sides of the conversation. In Handsfree mode, the user (or group of
users) uses both the handsfree microphone and speaker.
b. Group listening is switched on or off under the program key option *1. (M3820 and M3310 only)
