Panasonic KX-TGM420 Operating Instructions Manual page 130

• If the unit is connected to a PBX system, caller
information may not be properly received. Contact
your PBX supplier.
Missed calls
If a call is not answered, the unit treats it as a missed
call. The display shows "Missed call".
When there is a missed call, the message indicator
flashes slowly if the handset or base unit message
indicator's "Missed call" setting is enabled (page 61).
Note:
• Even when there are unviewed missed calls,
"Missed call" disappears from the standby display if
the following operation is performed by one of the
units:
– A handset is replaced on the base unit or
charger.
– Pressing [OFF] on a handset.
Phonebook name display
When caller information is received and it matches a
phone number stored in the phonebook, the stored
name in the phonebook is displayed and logged in the
caller list.
