MICROSD CARD
Inside the Mitel 722dt, 732d and 742d DECT phones (underneath the battery) there is space for
an optional microSD card. This special microSD card stores the DECT phone’s log on data for
your communication system, all the main local device data, and the personal directory.
To insert the microSD card for 722dt, 732d, and 742d DECT phone’s, release the lock of the
battery cover by sliding the knob towards the right, then take it off. Remove the battery and the
belt clip. Place the micoSD in the slot provided.
Storing data on the microSD card ensures that, if the device is defective, it is possible to take the
card out and use it in a replacement device so operations can be maintained in the shortest
possible time and without having to log on again.
Commercially available microSD cards cannot be used.
Take note of the User Guide supplied with the card.
