REQUIRED FCC NOTICE

The Federal Communications Commission (FCC) has established rules which
govern data modem direct connection to the telephone network. A jack is
provided by the telephone company for the direct connection. Jacks of the
modular type required for the connection are not provided on party lines
or coin lines.

If the data modem is malfunctioning, it may be affecting the telephone
lines outside the permissable operating specification of FCC 68. In this

case, the modem should be disconnected until the source of the difficulty

is traced.

This equipment generates and uses ratio frequency energy and, if not

installed in strict accordance with the installation and operating

instructions, may cause interference to radio and television reception.
The modem has been type-tested and found to comply with the limits for a
Class B computing device in accordance with the specifications of Subpart

J of Part 15 of FCC Rules, which are designed to provide reasonable

protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a
particular installation. If this modem does cause interference to radio
or television reception, which can be determined by disconnecting the
modem, the user is encouraged to try to correct the interference by

changing the position of the computer with respect to the television or

radio. ^

THE 1650 AUTOMODEM: A PIONEERING ACHIEVEMENT IN TELECOMPUTING

Commodore wants everyone to take an active part in the Computer
Revolution. That's why we invent products that are revolutionary in
technology and in price. That's also why we introduce products that make
your computer easier to use. Your new 1650 AUTOMODEM is one example of
our commitment to making state-of-the-art home computer accessories that
are reliable, easy to use, and reasonably priced. The AUTOMODEM lets you

use your telephone to connect your computer to other computers and to
large computer information services, such as CompuServe, the Source, Dow

Jones, and the Commodore Information Network.

The AUTOMODEM works with either the Commodore 64 or the VIC 20 personal

computer. This package contains a software cassette called TERM 64 to use

with a Commodore 64, and VICTERM I to use with a VIC 20.

The AUTOMODEM offers new features not present in the VICMODEM, which is
Commodore's other modem:

* Built-in Phone Adapter
* Built-in Y Adapter
* Automatic Answering
* Automatic Dialing

* Compatibility with any modular phone, including Trimline

Automatic dialing and answering make telecomputing even faster and easier.
These easy-to-use features are included in the TERM 64 program for the
Commodore 64. The VICTERM I program for the VIC 20 includes automatic
dialing, but not automatic answering.

TELECOMPUTING

Sending and receiving information on computers over phone lines is called

telecomputing. The AUTOMODEM translates electronic signals to and from

your computer so that those signals can be sent over phone wires to

another computer. Telecomputing lets you instantly perform tasks like
these:

* Sending work from one site to another,
* Copying programs and information from dial-up computer services,

* Sending and receiving electronic mail,
* Connecting your computer to almost any type and size computer.

FREE SUBSCRIPTIONS TO COMPUTER INFORMATION SERVICES

One of the extras we've included with your AUTOMODEM package is free
subscriptions to some of the computer information services that you can

use with your modem. For example, we've included a free subscription and
a free hour of CompuServe and Dow Jones as well as Comp-U-Card and General
Videotex (Delphi). The subscription to CompuServe includes access to the

Commodore Information Network, our own special information service for

Commodore computer users.

Here are just some of the services available through CompuServe and the

Commodore Information Network:

With your new modem, you can access information resources that up to

now only the largest libraries and businesses could afford. If you're
a programmer, you can use different computer languages and programming

tools. Both programmers and non-programmers can take advantage of the

many personal services offered through this network.

* educational programs
* sports scores
* software encyclopedia
* computer games
* spelling aids
* home budgeting
* electronic mail
* Commodore Product News

GETTING STARTED: STEP-BY-STEP INSTRUCTIONS

Please read this entire manual before you turn on your computer. Later

in this manual we'll explain how to use the necessary software. Here
is a step-by-step explanation of how to connect and use the modem:

INSTALLING THE AUTOMODEM

1. Make sure your computer is turned OFF. Whenever inserting or
removing any cartridge, make sure your computer is off.

2. Insert AUTOMODEM into the User Port. The picture shows the VIC 20;
the user port is in the same position on the Commodore 64.

3. Turn your computer ON.

CONNECTING THE TELEPHONE

You must have a MODULAR phone, but you do not need a modular handset
because the AUTOMODEM is plugged into the cord at the base of the

phone, not the cord on the handset. The AUTOMODEM has a built-in phone
adapter, which means that you can use the modem with ANY TYPE OF

MODULAR PHONE, including the Trimline model.

1. Set the Originate/Answer switch on the side of the modem to the
correct position. You should push the switch to the 0 (Originate)
position when you are sending information from your computer. For
example, this switch should be in the 0 position when you connect to

the Commodore Information Network. Set the switch to A when you are
receiving a call from another computer. For example, if you plan to
receive a program from a friend, the friend will start in Originate

mode, and you will start in Answer mode.

2. Set the Full/Half Duplex switch according to the requirements of
the service you are using. There are some additional instructions in

the AUTOMODEM box that show which choice to make.

3. Set the Telephone/Data switch. This switch lets you keep the
AUTOMODEM attached to your phone even when you aren't using the modem.
Just set the switch to the D (Data) position when you want to use the
modem, and T (Telephone) when you want to use your phone for regular

calls.

4. Unplug the phone line from the base of your modular phone. Insert
the phone line into the socket marked LINE on the AUTOMODEM (see figure

2). Plug one end of the other line into the socket marked PHONE on the
AUTOMODEM. Plug the other end into the back of the phone. Now your
computer is ready to be operated as a terminal.

If you are using one of the computer information services, refer to the
instructions you received with your subscription.

DISCONNECTING THE AUTOMODEM

Manually disconnect the AUTOMODEM by setting the Telephone/Data (T/D)
switch to the Telephone (T) position. Although the AUTOMODEM is still
connected to your telephone, the modem is off and the phone works
normally.
