System Does Not Answer After Correct Number of Rings
See “Program Ring Time” in SET UP SYSTEM FEATURES to change how
long the phone should ring before the system answers a call.
D-TAD features only work when the answering system is turned on.
If a fax machine shares a line with the answering system turned on, the
Ring Time must be programmed to allow the fax machine to answer
calls first. (See “Receiving a Fax When the Answering System Is On” in
ANSWERING SYSTEM (D-TAD) OPERATION.)
System Will Not Record Messages
When memory is full, saved messages must be deleted before new
messages can be recorded.
System Does Not Respond to Remote Commands
Make sure you are calling from a touch tone phone. When you dial a
number, you should hear tones. If you hear clicks instead, the phone is
not a touch tone telephone.
There may be noise or interference on the phone line you are using.
Press dial buttons firmly.
You might be calling from a phone that sends tones too short for the
964 to detect.
No Caller ID Information Received
Caller ID information is transmitted by the telephone company between
the first and second rings. Allow your phone to ring at least twice to
receive Caller ID information.
NEW CALLS Light Flashes
Make sure you have reviewed all messages on all lines.
It may be a false indicator from the Central Office. To clear, see “Reset
COVM Indicator” in CALLER ID OPERATION.
Line Lights Remain On When No Line is Connected
Make sure the system is programmed for that line to be absent. (See
“Set Line Usage for Each Line” in SET UP SYSTEM FEATURES.)
Make sure that your Line Groups are programmed properly. (See
“Assign the Line Group for this Phone”in SET UP SYSTEM FEATURES.)
Disconnect all other devices (fax, modem, credit card reader, etc.) from
any lines connected to your 964 phone. These devices can interfere
with the system’s data links.
Make sure the total length of telephone wiring used in your 964
system is less than 600 feet. If the wiring is longer, you may need to
use a special filter device. Call 1 800 222-3111 for information about
this filter. You’ll need to contact a professional to install this filter.
Tone Signals Do Not Activate a Remote Device
Tone signaling does not work during conference calls.
The phone generates tones of fixed duration, which may not be long
enough to activate some devices such as answering machines.
Operation During a Power Failure
Only Line 1 will operate during a power failure if a charged battery has
been installed. You will be able to dial and answer calls, but no other
features will work until power is restored.
No Caller ID Information While on a Call
You must subscribe to combined Caller ID with Call Waiting as a
single service to see Call Waiting information.
Make sure the TEL SET and TEL LINE cords are not reversed.
Display Screen is Blank
Make sure the power cord is connected to both the phone and an
electrical outlet not controlled by a wall switch.
Messages are Incomplete
If message length is programmed to one minute, messages longer than this
will be cut off. See “Program Message Length” in SET UP SYSTEM
FEATURES to change message length to unlimited.
