Siemens optiPoint family - Manual (Page 38)

The optiPoint “busy” light panel.
Similar in appearance to the key module,
but with 90 light-emitting diodes and
function keys. For use with
the Attendant console on
Hicom 150 E/H and
HiPath 3000.
The headset.
For those who prefer to work
with a lightweight headset, this
too can be connected to a system
telephone, provided that an
acoustic adapter is installed. Or
to the built-in interface on the
optiPoint 500 advance.
