This section describes other tasks you can perform, if required, on the MBU and the
Aastra 420d Handsets.
Resetting the MBU
In order for handsets to register with the MBU you must press the RESET button on
the rear of the MBU. Each time you reset the MBU, the handsets must re-register.
Make sure handsets are within range of the MBU to register properly.
Note: When you reset the MBU, the MBU waits until active calls have been
completed on the handsets before starting the reset process. If a registered handset is
off during an MBU reset, it reconnects when turned on as long as the MBU was not
factory defaulted.

• Press and release the
RESET button on the rear of the MBU (do not hold it down)

use.

the MBU after the reset is complete.
