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
77 for 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.
