Preparing the phone for message waiting indication (MWI)
The phone can detect various types of notifications (polarity reversal, high voltage
and frequency shift keying (FSK). The notification type is set with the MWI switch
on the underside of the phone. "0" = Off, "HV" = High voltage, "−/+" = Polarity re-
versal. The notification type Frequency reversal (FSK) is always active, regardless of
the switch setting (Aastra 6730a only).
The Aastra 400 communication servers support the following notification types:
Tab. 82
Supported notification types
The red MWI LED under the notification key can only be controlled with the Aastra
470 communication server and the notification type Polarity reversal. Set the
switch on the underside of the phone to the symbol "−". This applies to a straight
connecting cable (provided with the phone). If the MWI LED is ON after the phone
is connected, although no message is waiting for the phone, the switch must be set
to "+".
Notes:
– For the notification type FSK, a new message with a small envelope is
displayed on the screen of the phone Aastra 6730a. This variant is not
recommended as the symbol can be easily overlooked.
– The information in this section basically applies to analogue phones
Aastra 1910 and Aastra 1930 too. In these models the MWI switch is
labelled on the rear side of the phone, and the switch settings for
polarity reversal, with PR1 and PR2.
Mounting the phone on the desktop

phone until they engage. 4 different set-up angles are possible, by choosing the
cut-outs and turning the set-up feet.
Mounting the phone on the wall
