Vtech 1721 User Manual

INTRODUCTION

Congratulations! You have pur­chased one of the most sophisticated
cordless telephones on the market!
The VTech VT 1721 has been de­signed to offer a new standard in cord­less telephone technology.

Unlike most other cordless phones,
the VTech VT 1721 digitizes your voice
using advanced 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 1721 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 1721 decodes and
displays name and number Caller ID
(CID) information where available and
when subscribed to. The alpha-nu­meric display will show both the name
and number of the calling party (when
available). Up to 15 name characters
and/or 11 phone number digits can be
displayed on the LCD.

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.

The VTech VT 1721 also provides a
one-way Page/Find. Pressing the Base
Unit 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 1721 uses special
memory in both the Base Unit and
Handset which is not susceptible to
power failures. This provides perma­nent storage of all speed dial numbers,
CID information as well as the Base
Unit and Handset security codes.

When a spare battery is installed in
the Base Unit, the VTech VT 1721 uses
this battery 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 4 hours backup will be possible
with a fully charged battery in the Base
Unit.

With the VTech VT 1721, the user
can easily answer a call by pressing
any key other than the OFF or VOLUME

The phone will also alert you when
you are Out of Range even when you're
not using the phone!

this telephone equipment, please con­tact:

VTECH CUSTOMER SERVICE DE­PARTMENT at 1-800-595-9511.

The equipment has been tested and
found to comply with part 15 of the FCC
rules. These limits are designed to
provide reasonable protection against
harmful interference in a residential
installation. This equipment gener­ates, uses and can radiate radio fre­quency energy and, if not installed and
used in accordance with the instruc­tions, 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.

- Consult the dealer or an experienced

radio/TV technician for help.

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.

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.

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 Limited
Warranty.

IC (Industry Canada)

This telephone is registered for use

in Canada.

Notice:The Ringer Equivalence
Number(REN) assigned to each termi­nal device denotes the percentage of
the total load to be connected to a
telephone loop which is used by the
device, to prevent overloading. The
termination of a loop may consist of any
combination of devices subject only to
the requirement that the sum of the
Ringer Equivalent Numbers of all de­vices not exceed 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

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 VTech VT 1721 is designed to

INSTALLING THE BATTERY PACK

The Handset of your VTech VT

1721 cordless telephone is powered

by a rechargeable battery pack. It
charges automatically whenever the
Handset is in the Base Unit. 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 low battery message is dis­played:

• The Handset seems completely
dead, the LCD is completely clear
and does not activate when you
press the keys.

tween charges is 7 hours of continu­ous talk time or 14 days of stand by.

Alternatively, if you have purchased
a 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 Unit
charger. Place the drained Handset
battery pack into the Base Unit charger
so that it will charge.

The Base Unit spare battery charger
does NOT charge a battery pack as
quickly as the main Handset battery
charger. A full charge requires 24
hours.

A WORD ABOUT RECHARGE­ABLE BA TTERIES

Your Ni-Cad battery pack recharges
whenever the Handset is returned to
the Base Unit.

battery pack is charging. It is recom­mended that the battery pack be
charged for at least 16 hours initially.
Afterwards, 8 hours of maintenance
charging should be sufficient. 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 be-

The battery pack can be recharged
many times but if you get a low-battery
signal even after 8 hours of charging in
the Base Unit cradle (or 24 hours in the
Base Unit spare battery charger), the
battery pack(s) should be replaced.

the eyes or skin. It may be toxic
if swallowed.

4.Exercise care in handling batteries
in order not to short the battery with
conducting materials such as rings,
bracelets, and keys. The battery
pack or conductor may overheat
and cause burns.

To purchase replacement battery

SP ARE BA TTERY CHARGER /
POWER BACKUP FUNCTION

When an optional Spare Battery pack
is installed in the Base Unit, the VT
1721 uses this battery to provide op­erational backup in case of a power
failure. If you have a fully charged
battery pack in the Spare Battery
charger and there is a power outage,
you will still be able to place and re­ceive calls on the VT 1721 Handset for
up to 4 hours.

The Spare Battery pack can also be
used to replace a drained Handset
battery to ensure uninterrupted use.
Be sure to put the drained battery pack
in the Spare Battery charger.
