V-tech VT1923 User manual

1
Congratulations! You have purchased
one of the most sophisticated cordless
telephones on the market! The VT
1923 has been designed to offer a new
standard in cordless telephone
technology.
Unlike most other cordless phones, the
VT 1923 digitizes your voice using
advanced ADPCM digital voice coding
to provide noise and distortion free
performance. In most conditions you
will not be able to tell you are using a
cordless phone. Gone are the
annoyances of static, interference and
having to listen to other people's
conversations on your cordless phone.
The VT 1923 scrambles your voice
before it transmits it. This allows you
the security of knowing that no one can
tune in and eavesdrop on your
conversations.
The VT 1923 decodes and displays
name and/or number Caller ID (CID)
information where available and when
subscribed to. The alpha-numeric
display can show both the name and
number of the calling party. Up to 24
name characters or 11 phone number
digits can be displayed on the LCD.
With the VT 1923, the user can easily
answer a call by pressing any key other
than the OFF, MUTE or VOLUME
Keys. In addition, the Handset keypad
INTRODUCTION
and LCD illuminate while the Handset
rings to signs an incoming call. This is
very useful in a dark enviroment. The
VT1923 also provides a one-way
Page/Finf. Pressing the Base PAGE
key will cause the Handset to ring in
a manner which distinguishes it from
normal incoming ringing. This can be
used to alert the Handset user, or to
simply locate the Handset in the event
that it is misplaced.
The VT 1923 uses special memory in
both the Base and Handset which is
not susceptible to power failures. This
provides permanent storage of all
memory dial numbers, CID information
as well as the Base and Handset
security codes.
When an optional battery pack is
installed in the Base unit, the VT 1923
uses this battery pack to provide
operational backup in case of power
failure. In this way you have access
to all normal phone functions during a
total power outage. Calls can still be
placed and received without
interruption. More than 5 hours backup
will be possible with a fully charged
battery pack in the Base unit.
The VT 1923 informs you that another
extension is currently in use on the
same phone line. The phone will also
alert you when you are Out of Range,
even when you're not using the phone!

than OFF, MUTE, or the Volume
Keys on the Handset to answer.

may cause harmful interference to
radio communications. However, there
is no guarantee that interference will
not occur in a particular installation. If
this equipment does cause harmful
interference to radio or television
reception, which can be determined by
turning the equipment off and on, the
user is encouraged to try and correct
the interference by one or more of the
following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between
the equipment and receiver.
• Connect the equipment into an
outlet or on a circuit different from
that to which the receiver is
connected.

FCC AND IC REGULATIONS

FCC AND IC REGULATIONS
FCC Part 68
The FCC requires that you connect
your cordless telephone to the
nationwide telephone network through
a modular telephone jack (USOC
RJ11C, RJ11W or RJ14).
Your telephone company may
discontinue your service if your
equipment causes harm to the
telephone network. They will notify
you in advance of disconnection, if
possible. During notification, you will
be informed of your right to file a
complaint with the FCC.
Occasionally,your telephone company
may make changes in its facilities,
equipment, operation, or procedures
that could affect the operation of your
equipment. If so, you will be given
advance notice of the change to give
you an opportunity to maintain
uninterrupted service.
The Base Unit contains no user
serviceable parts. The Handset
contains a user replaceable battery
pack.
If it is determined that your telephone
equipment is malfunctioning, the FCC
requires that it not be used and that
it be unplugged from the modular jack
until the problem has been corrected.
Repairs to this telephone equipment
can only be made by the manufacturer
or its authorized agents or by others
who may be authorized by the FCC.
For repair procedures, follow the
instructions outlined under the VTECH
Limited Warranty.
This equipment may not be used on
coin service provided by the phone
company or Party Lines.
The REN is useful in determining the
number of devices you may connect
to your telephone line and still enable
the devices to ring when you receive
a call. The general rule is that the REN
value should not exceed 5.0 total;
however, contact your local telephone
company for the specific number in
your area.

IC (Industry Canada)
This telephone is registered for use in
Canada.
Notice: The REN assigned to this
device denotes the number of
devices you may connect to
the telephone loop which is
used by the device to prevent
overloading The termination
on a loop may consist of any
combination of devices
subjected only to the
requirement that the sum of
the REN does not exceed five
(5.0)
Notice: The Industry Canada label
identifies certified equipment.
This certification means that
the equipment meets certain
telecommunications network
protective, operational and
safety requirements. The
Department does not
guarantee the equipment will
operate to the user's
satisfaction.
Before installing this equipment, users
should ensure that it is permissible to
be connected to the facilities of the
local telecommunications company.
The equipment must also be installed
using an acceptable method of
connection. The customer should be
aware that compliance with the above
conditionsmaynotpreventdegradation
of services in some situations.
Repairs to certified equipment should
be made by an authorized Canadian
maintenance facility designated by the
supplier. Any repairs or alterations
made by the user to this equipment,
or equipment malfunctions, may give
the telecommunications company
cause to request the user to disconnect
the equipment.
Users should ensure for their own
protection that the electrical ground
connections of the power utility,
telephone lines and internal metallic
water pipe system, if present, are
connected together. This precaution
may be particularly important in rural
areas.
Caution: Users should not attempt to
make such connections
themselves, but should
contact the appropriate
electrical inspection
authority, or electrician, as
appropriate.
Your VT 1923 is designed to operate
at the maximum power allowed by the
FCC and IC. This means your Handset
and Base Unit can communicate only
over a certain distance - which will
depend on the location of the Base Unit
and Handset, weather, and the
construction and layout of your home
or office.
