The variable data in
the LCD display is
all solid rectangles.
(See "Handset
Display" in Chapter
2 for location of the
variable data in the
display.)
Check the following in the order provided.
1
Check the line cord connections at the Business
Cordless 905 telephone and at the communications
system switch.
2
If the connections are good, check to see if the
other telephones on the system are working. If they
are not, there is a problem with the switch.
3
If the other telephones are working, take the
following steps.
• For PARTNER Communications Systems: At the
same station port, replace the Business Cordless
905 telephone with a corded PARTNER
telephone or with another working 905 telephone.
• For MERLIN Communications Systems: At the
same station port, replace the Business Cordless
905 telephone with another working 905
telephone, or connect a corded MERLIN
telephone with a standard MERLIN line cord. (A
corded MERLIN telephone will not work if used
with the special MERLIN cord required for the 905
telephone.)
Attempt to place an intercom call. If you still do not get
an intercom dial tone, the system port or wiring is bad.
If you move the Business Cordless 905 telephone to
another station port on the system, the new port will
have to be reprogrammed. See "PARTNER Systems"
or "MERLIN Systems" in Chapter 4 for more
information.
