Important Safety Instructions
1. Read and follow all warning notices and instructions marked
on the product or included in the manual.
2. This product is intended to be used with a three-wire
grounding type plug – a plug which has a grounding pin.
This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the
grounding type plug by modifying the plug or using an
adaptor.
Prior to installation, use an outlet tester or a voltmeter to
check the ac receptacle for the presence of earth ground. If
the receptacle is not properly grounded, the installation must
not continue until a qualified electrician has corrected the
problem.
If a three-wire grounding type power source is not available,
consult a qualified electrician to determine another method
of grounding the equipment.
3. Slots and openings in the cabinet are provided for
ventilation. To ensure reliable operation of the product and to
protect it from overheating, these slots and openings must
not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not
locate the product where persons will walk on the power
cord.
5. Do not attempt to service this product yourself, as opening
or removing covers may expose you to dangerous high
voltage points or other risks. Refer all servicing to qualified
service personnel.
6. General purpose cables are provided with this product.
Special cables, which may be required by the regulatory
inspection authority for the installation site, are the
responsibility of the customer.
7. When installed in the final configuration, the product must
comply with the applicable Safety Standards and regulatory
requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies
and inspection authorities to ensure compliance.

Safety Instructions
D3830-A2-GB91-30 August 1998
8. A rare phenomenon can create a voltage potential between
the earth grounds of two or more buildings. If products
installed in separate buildings are interconnected, the
voltage potential may cause a hazardous condition. Consult
a qualified electrical consultant to determine whether or not
this phenomenon exists and, if necessary, implement
corrective action prior to interconnecting the products.
9. In addition, if the equipment is to be used with
telecommunications circuits, take the following precautions:
– Never install telephone wiring during a lightning storm.
– Never install telephone jacks in wet locations unless the
jack is specifically designed for wet locations.
– Never touch uninsulated telephone wires or terminals
unless the telephone line has been disconnected at the
network interface.
– Use caution when installing or modifying telephone lines.
– Avoid using a telephone (other than a cordless type)
during an electrical storm. There may be a remote risk of
electric shock from lightning.
– Do not use the telephone to report a gas leak in the
vicinity of the leak.

Government Requirements and Equipment Return
Certain governments require that instructions pertaining to modem
connection to the public switched telephone network be included in the
installation and operation manual. Specific instructions are listed in the
following sections.
United States
Notice To Users Of The Public Switched Telephone Network
1. This equipment complies with Part 68 of the FCC rules. On the
equipment is a label that contains, among other information, the
FCC registration number and ringer equivalence number (REN)
for this equipment. The label is located on the bottom of the
Model 3830 modem.
2. Page A of this manual contains the Universal Service Order Codes
(USOC) associated with the services on which the equipment is to
be connected.
3. The Ringer Equivalence (REN) is used to determine the quantity
of devices which may be connected to the telephone line.
Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most, but not all areas,
the sum of the RENs should not exceed five (5.0). To be certain of
the number of devices that may be connected to the line, as
determined by the total RENs, contact the telephone company to
determine the maximum RENs for the calling area.
4. If the Model 3830 modem causes harm to the telephone network,
the telephone company will notify you in advance that temporary
discontinuance of service may be required. But if advance notice is
not practical, the telephone company will notify the customer as
soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.
5. The telephone company may make changes in its facilities,
equipment, operations, or procedures that could affect the
operation of the equipment. If this happens, the telephone
company will provide advance notice in order for you to make the
necessary modifications in order to maintain uninterrupted service.

from the network until the problem is resolved.
7. The user is not authorized to repair or modify the equipment
beyond replacing the ac line fuse. Refer to the installation section
of this manual for more information.
8. This equipment cannot be used on public coin service provided by
the telephone company. Connection to Party Line Service is
subject to state tariffs. (Contact the state public utility commission,
public service commission or corporation commission for
information.)
9. The Telephone Consumer Protection Act of 1991 makes it
unlawful for any person to use a computer or other electronic
device to send any message via a telephone fax machine unless
such a message clearly contains, in a margin at the top or bottom
of each transmitted page, or on the first page of the transmission,
the date and time it is sent, and an identification of the business, or
other entity, or other individual sending the message, and the
telephone number of such business, or other entity, or individual.
In order to program this information, follow the steps outlined in
the manual supplied with your fax software.
10. An FCC compliant telephone cord with modular plugs may be
provided with this equipment. This equipment is designed to be
connected to the telephone network or premises wiring using a

Canada
Notice To The Users Of The Canadian Public
Switched Telephone Network
The Canadian Department of Communications 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 the local
telecommunications company. The equipment must also be installed
using an acceptable method of connection. In some cases, the
company’s inside wiring associated with a single line individual service
may be extended by means of a certified connector assembly
(telephone extension cord). The customer should be aware that
compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any repairs
or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to
request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone line and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
CAUTION
Users should not attempt to make such
connections themselves, but should contact
the appropriate electric inspection authority,
or electrician, as appropriate.
The Load Number for this equipment is listed on page A of this
manual. The Load Number (LN) 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

COMSPHERE 3800 Series Modems – Model 3830
IAugust 1998 3830-A2-GB91-30
termination on a loop may consist of any combination of devices
subject only to the requirement that the total of the Load Numbers of
all devices does not exceed 100.
If your equipment is in need of repair, refer to the procedure in the
Government Requirements and Equipment Return section.
