BusinessPhone – Analog Telephone
Hearing aid compatibility
Since your telephone has a built-in inductive coupler for the hard-
of-hearing, anyone so desiring can use the telecoil in his/her
hearing aid while telephoning. To do so, simply switch the hearing
aid in the T position.
Message Waiting indication
Your incoming messages can be indicated by a rapidly flashing
Message key. It is well known that the line leads are twisted after
installation (the Message Waiting LED will be on when there is no
Message Waiting signal and will go off when there is a Message
Waiting signal). To solve this problem there are three possible
settings for the Message Waiting indication:
•
STD This setting should be used when no Message Waiting
indication is required. This is also the default setting upon
delivery.
•
MW+. Use this position when Message Waiting indication is
required and the line cabling is straight.
•
MW-. Use this position when Message Waiting indication is
required and the line cabling is twisted.
At the bottom side of your phone:
Slide the switch to the required position.
Enable/Disable Program key
Note: This function is only supported for the
Dialog 4147 Medium phone.
Via a switch it is possible to enable or disable the program key.
When the switch is set in the Off position, no programming is
possible (i.e. the memory content is locked).
At the bottom side of your phone:
Slide the switch to the required position.
