You have no dial
tone
Check the following in the order provided.
1
Check to see if the PHONE light is on. If it is not,
press PHONE.
2
Refer to the line status indicators to verify that you
are active on a line or intercom. If not, press the
appropriate line button. If line status indicators do
not reset, you are not communicating with the
switch.
If you get dial tone on some of your lines, but not on
all of them, there is a problem with the specific line
or the switch, rather than with the telephone.

Check the line cord connections at the Business
Cordless 905 telephone and at the switch. If the
connections are good, do the following:
• 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.
