General corrective measures
_
GENERAL _____________________________
I cannot make and receive calls.
—The line cord is connected incorrectly or not
connected. Confirm the connection (see
page 11).
I cannot make calls.
—The setting of the dialing mode is wrong. Check
the selector (see page 11).
The unit does not work.
—Disconnect the unit from the telephone line and
connect a known working phone. If the known
working phone operates properly, call your
service personnel to have the unit repaired. If
the known working phone does not operate
properly, consult your telephone company.
The unit does not ring.
—The ringer volume is set to OFF.
Raise it to a suitable level (see page 12).
The REDIAUPAUSE button does not function
properly.
—The button has combination feature of redial
and pause. It will redial the last dialed number
when it is pressed after hanging up and getting
dial tone again (see page 17). If it is pressed
after you dial another phone number, the button
will function as pause button (see page 53).
While programming, I cannot enter the code or
ID number.
—The whole or part of the number you try to enter
is same as the other code or ID. Change the
number into new one (see pages 44, 45 and 59).
FAX TRANSMISSION
The other party complains that letters on their
received document are distorted.
—If your line has special telephone services such
as call waiting, the service may have been
activated during the fax reception. Connect the
unit to a line that does not have such services.
—Another telephone connected to the same line
as your unit is connected is hung off. Hang up
and try again.
The other party complains that dirty patterns or
black line appear on their received documents.
—The glass or rollers on your unit are dirty. Clean
them (see page 73).
I cannot make an international fax call.
—Use the overseas transmission mode (see
page 49).
—Add two pauses at the end of the phone number
(see page 53).
FAX RECEPTION _______________________
I cannot receive documents automatically.
—The receive mode is set to TEL. Set the receive
mode to ANS/FAX, TEL/FAX or FAX.
—The time to answer the call may be too long.
Decrease the number of rings (see pages 25
and 26).
—The greeting message may be too long. Shorten
the message or ask the other party to press **
and then start transmission.
