13.2.1 BEFORE STARTING EASY REPLACEMENT PROCEDURE
1
Check that both the old handset (that is, the handset to be replaced) and the new
handset (that is, the replacement handset) are of the same device type (for
example DT413).
2
Make sure that the handset batteries are charged before starting the easy
replacement procedure.
3
Switch off the new handset by long pressing
.
13.2.2 EASY REPLACEMENT PROCEDURE
During the Easy Replacement procedure, the LEDs of the handset and the charger
follow the same LED indications. This means that if the old handset has a broken
display, the LED indications on the charger and on the handset can be used to follow
the replacement procedure. Before and after easy replacement, the LEDs may have
different LED indications. For more details, see
LED Indications during Easy
Replacement
on page 79.
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
14
Troubleshooting
on page 81 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.
1
On the new handset, press and hold
Note: Do not release
until you are instructed to do so.
2
Put the new handset in the charger.
