properly. Inspect the line cord connections
at the modular jack and at the telephone.
Also inspect the coiled handset cord con-
nection at both ends.
❥Unplug the telephone and connect it
to another modular jack.

PROBLEMS WITH MESSAGE WINDOW
OR INDICATOR LIGHTS
Make sure all plugs are connected
properly. Inspect the line cord connections
at the modular jack and at the telephone.
Make sure the power cord is securely
plugged into an electrical outlet not
controlled by a wall switch.
TELEPHONE DOES NOT RING
❥Make sure the Ringer Volume switch
for the silent line is set to LO or HI.
❥If there are several other telephones
on the same line, try disconnecting some
of the other telephones. Having too many
telephones connected can also create
problems such as low ringer volume, or
impaired sound quality during calls.
LOW BATTERY LIGHT IS ON
❥Make sure the batteries are installed
correctly.
❥If the light remains on, replace all 4
batteries with new batteries.
L1 or L2 ON/OFF LIGHT
FLASHES RAPIDLY
If both lights are flashing, then memory
may be full. See “When Memory is Full.”
If one or the other light is flashing, the
flashing line might be set to Announce
Only, and no announcement is recorded for
that line. If you recorded an announce-
ment for AO, it might have been lost in a
power failure. Try recording a new an-
nouncement for AO, or switch to a differ-
ent announcement. See “Recording an
Announcement.”
SYSTEM DOES NOT DISCONNECT
WHEN YOU ANSWER FROM
ANOTHER TELEPHONE
The answering system will not always dis-
connect if you answer the call from another
phone at the same time that the system
answers. To stop the answering system,
press S, or quickly press and release
the switchhook on the phone you are using.

should be reset. See “Setting the Clock.”
SYSTEM DOES NOT RESPOND TO
REMOTE COMMANDS
❥If power failed when the backup
batteries were missing, or battery power
was low, the Remote Access Code might
have returned to its factory setting. See
“Remote Access Code.”
❥If you are using dial buttons to enter
remote commands, make sure you are call-
ing from a touch tone phone. When you
dial a number, you should hear tones; if
you hear clicks instead, the phone is not
using touch tone service.
❥Some telephones transmit only one
brief tone each time you press a number.
If you are using one of these telephones,
the answering system might not detect the
RemoteAccess Code while the announce-
ment is playing. Wait until the announce-
ment is over and enter the code again.
❥There might be noise interference on
the phone line you are using. Press firmly
on the number buttons.
❥Make sure you are entering the
Remote Access Code correctly.
❥If you are using voice-activated
commands, make sure you are responding
to the prompts in a clear, audible voice.

to 4 minutes long. If a caller leaves a very
long message, part of it might be lost when
the system disconnects the call after 4
minutes.
❥If the caller pauses for more than 7
seconds, the system stops recording and
disconnects the call.
❥If the system’s memory fills up
during a message, the system stops
recording and disconnects the call.

ANSWERING SYSTEM OPERATION
Away From Home
Voice Activated Commands
When a touch tone telephone is not avail-
able, you can still call the system to listen
to your messages. Use your voice to enter
the Remote Access Code, to repeat the
messages, and to delete messages.
Speak in response to the prompts presented
by the system as described below. You
must speak quickly and loudly in order for
the system to detect your voice.
The system does not recognize the actual
words you are saying; it responds to any
sufficiently intense auditory signal. For
example, you could say any phrase that is
easy for you to remember, instead of say-
ing "Enter Code."
You can hang up at any time during the
call. The system saves your messages,
unless you respond to the "Delete all mes-
sages?" prompt.
1Dial your telephone number, listen for
the announcement, and then remain
silent after the beep.
If the system answers after 10 rings
(because it is off or the memory is full),
remain silent after the two-beep signal.
2After about 10 seconds, the system
prompts "Enter remote access code."
Immediately respond by saying "Enter
code."
3You then hear, "First digit," followed by
"Enter 4," "Enter 5," "Enter six," and so
forth. When you hear the first digit of
the Remote Access Code, immediately
respond by saying "Enter code."
For example, if your Remote Access
Code is 543, wait to hear "Enter five,"
then say "Enter code."
4You then hear "Second digit," followed
by "Enter zero," "Enter one," Enter two,"
and so forth. When you hear the second
digit of the Remote Access Code, say
"Enter code."
5You then hear "Third digit," followed by
"Enter zero," "Enter one," Enter two,"
and so forth. When you hear the third
digit of the Remote Access Code, say
"Enter code."
6If you enter the code correctly, the
system announces how many messages
have been received for each mailbox,
and begins to play all the messages.
If no messages have been received, the
system disconnects the call.
7At the end of each messages, the system
prompts "Repeat message?" To hear the
message again, say "Repeat message."
If you remain silent, the system plays
the next message. You can repeat each
message once.
8After the last message plays, the system
announces "End of messages" followed
by the prompt "Replay messages?"
To replay all the messages, say "Replay
messages." If you remain silent, the
system prompts "Delete all messages?"
9To deleteall the messages you justheard,
say "Delete messages." The system then
repeats the "Delete all messages?"
prompt to confirm your choice. To
confirm the delete, say "Delete
messages." The system announces
"Messages deleted." If you remain silent
after the "Delete all messages?" prompt,
the messages are not deleted.
If you do not enter
the correct Remote Access Code.
If you enter an incorrect Remote Access
Code, the system beeps five times and be-
gins the sequence of prompts again. If you
enter the wrong code on the second try, the
system disconnects the call.
If you do not respond to the correct digit
whileentering the RemoteAccessCode (or
if the system fails to detect your response),
you can remain silent until after you hear
the "Enter nine" prompt. The system beeps
five times and begins the sequence of
prompts again. If you do not respond cor-
rectly during the second sequence of
prompts, the system disconnects the call.
