Registering the 420d Handset

Each handset must be registered with your MBU 400 gateway before it can be used. If the handset is not registered, one of the following message appears on the handset displays:

Searching for Gateway

or

Please place handset in charger to start auto-registration with the gateway. Reset the gateway to enable registration mode.

To register your handset do the following.

1.Ensure the base unit is connected to power.

2.Place the handset in the charger.

3.If the handset does not register automatically, press and release the RESET button on the side of the MBU 400.

Pressing RESET reboots the MBU, following which it remains in registration mode for 5 minutes. More than one handset can be registered in this period. To start a new 5 minute registration period, press and release the RESET button again.

Successful registration ends with the idle screen on the handset as shown in the section Handset Idle Screen on page 25.

Note: If you encounter problems registering your handset, try removing the handset from the charger and replacing it, then resetting the MBU once again. If you have changed the gateway access code, see Changing the Access Code on the Handset on page 29 to change the handset access code so it matches the gateway.

Handsets can be registered and de-registered through the handset menu options. See Manually Registering/De-registering a Handset on page 60 for further information.
