Optional accessories
All of the following accessories are optional and can be purchased
at your local Aastra contact.
Belt clip, swivel-type
The ordinary belt clip can be replaced with a special swivel-type
belt clip adapted to firmly place your phone onto your belt.
Leather casing
The leather casing is especially designed for the phone. The casing
comes with the swivel-type belt clip and the phone is fully
operational while placed in the casing.
Note: The leather case may not be used in potentially
explosive areas.
Headset
A headset is recommended if you frequently use the phone, and/or
want to have both hands free. The phone has a special headset
connector that is waterproof. The headset comes in three versions;
with microphone integrated in the cable (with or without adapter),
with microphone on a boom, and with hearing protection (Peltor).
An adapter, that makes it possible to connect other standard types
of Peltor headsets, is also available.
Notes:
The phone must be equipped with the factory mounted
headset connector.
The headset answering button is only active during a call or
when the phone is ringing and cannot be used to get a line
when making a call.
Microphone integrated in the cable, microphone on a boom
and headset adapter may not be used with DT432.
ATEX headset information (DT432)
• It is not allowed to use any other headsets than the Peltor ATEX
headsets connected via the ATEX headset adapter. Using any
other headset or headset adapter will void the ATEX approval.
