Base Unit

This equipment complies with Parts 15

and 68 of the Federal Communications

Commission (FCC) rules for the United

States. It also complies with regula-

tions RSS210 and CS-03 of Industry

and Science Canada. Operation is

subject to the following two conditions:

1. This device may not cause interfer-

ence, and

2. This device must accept any inter-

ference, including interference that

may cause undesired operation of

the device.

A label is located on the underside of

the base unit containing either the

FCC registration number and Ringer

Equivalence Number (REN) or the IC

registration number and Load Number.

You must, upon request, provide this

information to your local telephone

company.

This equipment is compatible with

inductively coupled hearing aids.

Should you experience trouble with

this telephone equipment, please con-

tact:

VTECH COMMUNICATIONS

SERVICE DEPT. at 1-800-595-9511.

For repair/warranty information. The

telephone company may ask you to

disconnect this equipment from the

line network until the problem has

been corrected.

FCC Part 15

Warning: Changes or modifications to

this unit not expressly approved by the

party responsible for compliances could

void the user's authority to operate the

equipment.

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 resi-

dential 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 inter-

ference to radio communications.

However, there is no guarantee that

interference will not occur in a particu-

lar 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 REGULATIONS

FCC Part 68

The FCC requires that you connect

your cordless telephone to the nation-

wide telephone network through a

modular telephone jack (USOC RJ11C,

RJ11W or RJ14).

Your telephone company may discon-

tinue 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 uninter-

rupted service.

The base unit contains no user ser-

viceable 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 in-

structions 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.

FCC REGULATIONS

When using your telephone equip-

ment, basic safety precautions should

always be followed to reduce the risk

and the cabinet has been dam-

aged.

f. If the product exhibits a distinct

change in performance.
