MItel 622d, 632d, 650c: Note on operating the SD card in
a replacement device
In the event of a faulty device, try to use the SD card from a
Mitel 622d, 632d or 650c on another Mitel 622d, 632d or 650c
DECT phone whenever possible. If the replacement device is
a Mitel 620d /630d, the replacement device will only transfer
whatever Mitel 622d, 632d or 650c data it is capable of
handling (this means programmed keys may be adopted
differently or not at all).
If a SD card from a Mitel 620d / 630d is operated on a
Mitel 622d, 632d or 650c DECT phone, the Personal Directory
and the main device data will be adopted.
