Samsung ITP-5121D 用户手册

The CONFERENCE button allows the user to set up a call with up to 5 parties (sta-
tion or trunk).

Transfer is used to send any call to another extension in one of two ways. You can
do a screened transfer by informing the other extension who is calling or you can
do a blind transfer without notification.

The  HOLD button maintains the call at your keyset, while enabling you to call
other stations or consult coworkers in confidence.

The SPEAKER button allows you to initiate a conversation from the keyset with-
out lifting the handset or switch to speaker phone mode if you are currently on
handset.

This user guide is written based on the default access code for using system fea-
tures. If the system numbering plan has been changed some of the access codes
may not be correct. Your installing company can inform you of the correct codes.

The system provides several tones to assist you. Some of these tones are already
