A key extension Aastra M671 (KeyExtension 73P) offers only one level.
Labelling a Key on the Key Extension
Paper strips are used for labelling the key on the Aastra M671 (KeyExtension 73P) key
extension. The keys are either labelled with the default text on the Aastra M676
(KeyExtension 75D) (e. g. when programming a feature key) or by entering an indi-
vidual text when programming the key (see also the chapter Labelling the Keys
starting on page 20).
Using a Headset
You can telephone hands-free if you use a headset. A headset connected to a system
telephone can be switched on and off at the telephone (see also page 114 in the
chapter entitled
MenuCard “Phone Settings” ). If the headset is switched on, you can
accept or end a call by pressing the headset key
K
on the system telephone,
which switches off the microphone and handset on the telephone. If the headset is
switched off, the headset key operating function on the system telephone is not oper-
ational.
Note
If a cordless DHSG headset is used, the headset key
K
on the system telephone is
operated with the Talk key on the headset.
Read the instructions for the headset in the user guide.
The headset can be used in combination with the handset and the other keys of your
system telephone (e. g. hands-free/open-listening key
L
). The following table
gives an overview of the different operating situations. The headset must be switched
on for these operations (see page 114).
