Congratulations! You have purchased
one of the most sophisticated cordless
telephones on the market! The VTech
VT 1920c has been designed to offer
a new standard in cordless telephone
technology.
Unlike most other cordless phones, the
VTech VT 1920c 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 VTech VT 1920c 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 VTech VT 1920c decodes and
displays name and/or number Caller ID
(CID) information where available and
when subscribed to. The alphanumeric 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 VTech VT 1920c, the user can
easily answer a call by pressing any
key other than the OFF, MUTE or
VOLUME Keys. In addition, the handset
keypad and LCD illuminate while the
handset rings to signal an incoming
call. This is very useful in a dark
environment.
INTRODUCTION
The VTech VT 1920c also provides
a one-way Page/Find. 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 VTech VT 1920c 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 VTech VT
1920c 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 VTech VT 1920c 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!

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 5.0A 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

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
conditions may not prevent degradation
of services in some situations.
Repairs to certified equipment should
be made by an authorized Canadian
maintenance facility designated by the

REPLACING THE BATTERY PACK
spare battery pack and it has been
charging in the base unit, simply
exchange the drained handset battery
pack with the fully charged replacement battery pack from the base
charger. Place the drained handset
battery pack into the base charger to
recharge.
The base spare battery charger does
NOT charge a battery pack as quickly
as the handset battery charger. A full
charge requires 24 hours when using
the spare battery charger.
IT’S IMPOSSIBLE TO OVERCHARGE THE BATTERY PACK
The battery pack can be recharged
many times, but if you get a low-battery
signal even after 16 hours of charging
in the base cradle (or 24 hours in the
base spare battery charger), the battery pack(s) should be replaced.
To purchase replacement battery
packs, call VTECH Communications at
1-800-595-9511. In Canada, call
VTECH Electronics at 1-800-267-

A WORD ABOUT RECHARGEABLE
BATTERIES
Your Nicad battery pack recharges
whenever the Handset is returned to
the Base Unit cradle. You may return
the Handset to its cradle whenever
you're not using the phone.
However, to
maximize
the life of your
battery pack, do not return your
VT
1920c
Handset to the Base Unit cradle
for recharging until the LOW BATT
LED begins to flash.
CHARGING THE HANDSET BATTERY PACK
The handset of your VTech VT 1920c
cordless telephone is powered by a
rechargeable battery pack. It charges
automatically whenever the handset is
in the base. You should charge the
battery pack for 16 hours when you first
receive your phone. You’ll know the
battery pack needs charging when:
• The phone emits a warning tone
when you press the PHONE key.
• The low battery message is
displayed:
• The handset seems completely
dead, the LCD is clear and the
handset does not beep when you
press the keys.
To Charge The Battery Pack
To charge the battery pack, place the
handset in the base unit. The CHARGE
indicator will light to show the handset
is seated properly and the battery pack
is charging. It is recommended that the
battery pack be charged for at least 16
hours initially and 8 hours for maintenance charging. You can use your
telephone before that with diminished
capacity, but it is best to charge the
battery pack fully. It will take several
recharge cycles to maximize the charge
capacity of your battery pack. The
maximum battery life between charges
is 7 hours of continuous talk time or
7 days of stand by.

REPLACING THE BATTERY PACK
Power Backup
When a Spare Battery pack is installed
in the Base Unit, the VTech VT 1920c
uses this battery pack to provide
operational backup in case of a power
failure. If you have a fully charged
battery pack in the Spare Battery pack
charger and there is a power outage,
you will still be able to place and
receive calls for up to five hours.
Replacing a Drained Handset battery
The Spare battery pack can also be
used to replace a drained Handset
battery pack to ensure uninterrupted
use. Be sure to put the drained battery
pack in the Spare Battery charger for
recharging.
Please note that the Spare Battery
compartment charges at a slower rate
than a battery pack charging in the
Handset. It takes 24 hours to fully
charge a battery pack in the Spare
Battery charger.
