The GIGAPHONE is an advanced cordless telephone that operates in the 2.4GHz
frequency range. Your GIGAPHONE is capable of supporting up to a maximum
of 8 Handsets. Using additional Handsets, several people can be using the
cordless system at the same time. Some examples:

* 2 Handsets conferenced on a Line 1 call; while 2 additional Handsets are
conferenced on a Line 2 call.
* 2 Handsets conferenced on a Line 1 call; while another Handset is in Intercom
mode with the Base Unit.
* 1 Handset on Line 1; a different Handset in Intercom mode with the Base
Unit; 2 additional Handsets are conferenced on Line 2.

This manual is designed to familiarize you with the GIGAPHONE cordless
telephone. We strongly recommend you read the manual before using your
phone.

Introduction

To order additional system Handsets (model# VT20-2420), battery
packs, or headsets, call VTech Communications Inc at 1-800-595-9511.

The VT20-2431 Handset and Base feature a user-friendly display, making it
easy to access the many features of this multi-Handset, cordless system. The
three black keys, found directly below the LCD screen, are called soft keys.
They are called this because their functions change depending on what you're
doing making a call, reviewing Caller ID, adding a name and number to your
Phone Book, etc.

For example, when the Handset is in the idle mode, the LCD displays:

In this case, the 3 soft keys access REDIAL, MENU and MEMORY.
When the Handset is active, the LCD displays:

In this case, the 3 soft keys access VOLUME, HOLD and MUTE.

Connecting to the telephone lines
Your 2-Line GIGAPHONE will work fine even if you only have one telephone
line. We recommend connecting the modular telephone cord to the jack labeled
LINE 1 / L1 + L2, located on the bottom of the Base Unit. Here are steps for
connecting 2 lines:

If you have 2 Lines coming out of a Single Wall Jack:
Connect a 4-wire (RJ-14) modular phone cord between the wall jack and the
phone jack labeled L1 / L1 + L2.

If you have 2 Lines, each coming out of Separate Wall Jacks:
Connect a modular phone cord from the wall jack you want to designate as
your LINE 1, to the LINE 1 / L1 + L2 jack on the bottom of the Base Unit. Next,
connect a phone cord from the remaining wall jack to the LINE 2 jack on the
Base Unit.

Data Port

Your 2-Line GIGAPHONE has a Data Port on the back of the Base Unit. This
port provides an easy way to connect your fax machine, laptop computer,
modem or other telephone device for direct access to LINE 2.

The Data Port only provides access to Line 2, so you must have an active line
connected to the LINE 2 jack on the bottom of the Base Unit. Connect a
modular phone cord from the Data Port (look for the small door marked DATA
on the back of the Base Unit) to your fax, laptop, etc.

NOTE: While the Data Port is in use, accidental use of Line 2 by a parallel
phone, your 20-2431, or a Call Waiting ID alert may interrupt the data transmis­sion.

Follow the steps below:

1. Remove the battery cover by

pressing on the indent and
sliding downward.

2. Place the new battery pack in the

handset with the metal contacts
aligned with the charge contacts
in the battery compartment.

3

. Replace the battery cover by

sliding it upwards.

4. If the new battery pack is not

already charged, place the
handset in the base unit, or a
remote charging stand, and allow
it to charge for 12 hours. After
initial charge, a maintenance
charge of 8 hours should be
sufficient.

Installation of Battery Pack in Handset

The original Handset that is shipped with your GIGAPHONE system will be
automatically registered to the Base. This Handset is HANDSET 1.

As you register additional Handsets to the system, they will be assigned
extension numbers in the following order: HANDSET 2, HANDSET 3,
HANDSET 4, etc.

Whenever a charged Handset battery pack is installed, the Handset will
automatically begin SEARCHING FOR BASE (if previously registered), or
it will prompt you to ENTER BASE ID to register the new Handset. See

Registration and Operation for details.

Charging Of Handset Battery Pack

The Handset of your GIGAPHONE 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 12 hours when you first receive your
phone. You'll know the battery pack needs charging when:

IMPORTANT:

1. Do not dispose of a battery pack in a fire, the cell may explode.

2. Do not open or mutilate the battery pack. Toxic substances may be released,
causing harm to eyes or skin.

3. Exercise care in handling battery packs in order to prevent an accidental
short of the charge contacts, potentially causing the battery pack to
overheat.

4. Do not dispose of this battery pack into household garbage. Contact your
local recycling organization for recommended disposal sites.

CORDLESS TELEPHONE SYSTEM:

1. Choose a central location for your Base Unit.

2. Install your Base Unit and Extension Handsets
away from electronic equipment, such as personal
computers, television sets and microwave ovens.

3. In locations where there are multiple cordless
telephones, separate base units as much as possible.

4. Install your telephone equipment away from
heat sources and sunlight.

5. Avoid excessive moisture, dust or extreme cold.

Spare Battery Charger/Power Backup Function

The GIGAPHONE uses the spare battery charger in the Base Unit to provide
operational backup in the event of a power failure. With the a fully charged
battery pack in the spare battery charger, you will still be able to place and
receive calls from the Handset for up to one hour. During Power Backup mode,
you will not be able to use the Base Unit.

The spare battery pack can also be used to replace a drained handset battery,
ensuring uninterrupted use.

NOTE :

When using the GIGAPHONE during Power Backup mode, audio quality may
be compromised due to reduced power availability.

1. Open the spare battery charger
by pressing the release button,
located on the left-hand side of
the Base Unit. A drawer will
open to reveal the spare battery
compartment.

2. Place a battery pack in the
drawer with the charge contacts
facing up and to the right.

3. Push the drawer closed.

The spare battery takes 24 hours to
fully charge a drained battery.
