Cordless Phones for MX-ONE™
IMPORTANT: Never remove a handset from the charger until the instructions in the display or
the LED tells you to do so (see status on the LED if the display is broken). If there is an error
indication it may be allowed to remove the handset, see
further instructions. After the old handset has been in the charger, the new handset needs to be
placed in the charger regardless if the replacement was successful or not. Failing to do so may
result in malfunction and the new handset will need to be sent for service.

with the old handset. The handset can either be switched on or off.
Note: If the CR3 Charging Rack is used, the left charging slot must be used for both
handsets.
The handset will be restarted and after a few seconds, the text "Saving settings. Do not
remove phone from charger" appears. The charger LED changes to slow orange
flashing. It may take several minutes.
IMPORTANT: If the old handset cannot communicate with the charger, put the new
handset in the charger to restore its settings (that is, the handset's IPDI). If this step is
not performed, the new handset must be sent for service. The old handset's settings
might be transfered to the new handset by using PDM. See the handset's Configuration
Manual.
