Step 3: Entitle the device to operate in restricted powering conditions
The restricted powering switch is located on the under-
side of the device. The recessed sliding switch can be
moved with a screwdriver.
If the switch points to the symbol A , your telephone is
entitled to operate in restricted powering conditions that
means that the important telephone functions can still be
used.
Step 4: Program the multiple subscriber numbers (MSNs)
We recommend that you enter the MSNs when first
putting the telephone into operation, because only then
you can use all the functions of your telephone. The
MSNs (Multiple Subscriber Numbers) are the call
numbers you were assigned for your ISDN connection.
These numbers are entered as follows:
In order to avoid unauthorized unplugging of the
telephone connecting cord from the telephone
socket, the plug is protected. Use a small
screwdriver or the like to unplug the connector.
If you connect more than one unit to your ISDN
connection, only one unit can be operated
during restricted powering. Mark this unit
accordingly!
