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 un-
derside of the phone. "0" = Off, "HV" = High voltage, "−/+" = Polarity reversal. The no-
tification type Frequency reversal (FSK) is always active, regardless of the switch set-
ting (Mitel 6730 Analogue only).
The MiVoice Office 400 communication servers support the following notification types:

Switched off
Polarity reversal
High voltage
Frequency reversal (FSK)
The red MWI LED under the notification key can only be controlled with the Mitel 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, al-
though 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 Mitel 6730 Analogue. 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
Feed the mounting feet into the corresponding cut-outs on the underside of the 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
1. Place the supplied drilling template for wall mounting on the wall position you want
and mark the positions for the mounting screws. Depending on the type of wall, you
may need some dowel plugs. Screws and dowel plugs are part of the delivery.
2. Put the telephone with the mounting openings over the heads of the wall screws
and pull the phone downwards to stop it.
