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 possible that the line leads to the phone could be
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.
On the bottom side of your phone:
Slide the switch to the required position.
Enable/Disable Program key
Note: This feature is only supported for the Dialog 4147
phone.
It is possible to enable or disable programming of the function keys
using a switch. When the switch is set in the Off position, no
programming is possible (i.e. the memory content is locked).
