Service manual

Regulatory Notices: Dell Latitude CP
If you have any questions about your telephone line, such as how many pieces of equipment you can
connect to it, the telephone company will provide this information on request.
In certain circumstances, it may be necessary for the telephone company to request information from you
concerning the equipment that you have connected to your telephone line. On request of the telephone
company, provide the FCC registration number and the ringer equivalence number (REN) of the
equipment that is connected to your line; both of these items are listed on the equipment label. The sum of
all the RENs on your telephone line should be less than five to ensure proper service from the telephone
company. In some cases, a sum of five may not be usable on a given line.
If Problems Arise
If your telephone equipment is not operating properly, immediately disconnect the modem from the
telephone line, as it may harm the telephone network. If the telephone company notes a problem, it may
temporarily discontinue service. When practical, it will notify you in advance of this disconnection. If
advance notice is not feasible, you will be notified as soon as possible. When you are notified, you will be
given the opportunity to correct the problem and informed of your right to file a complaint with the FCC.
If repairs are needed on your Dell notebook modem, they should be performed by Dell Computer
Corporation or an authorized representative of Dell Computer Corporation. To return products, you must
call Dell customer service at the toll-free number shown in
Getting Help, to receive a Credit Return
Authorization Number. For more information on returning equipment, see the
Total Satisfaction Return
Policy in, Warranties and Return Policy.
Installation and Labeling
Your Dell notebook modem provides all the connections necessary for proper operation. Connection to the
telephone network should be made with standard modular cords that connect to the jacks or the modem.
Load Number
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 termination on a
loop may consist of any combination of devices subject only to the requirement that the total of the LNs of
all the devices does not exceed 100. An alphabetic suffix is also specified in the LN for the appropriate
ringing type (A or B), if applicable. For example, LN = 20 A designates an LN of 20 and an "A" type ringer.
IC Notice (Canada Only)
Most Dell portable computers (and other Dell digital apparatus) are classified by the Industry Canada (IC)
Interference-Causing Equipment Standard #3 (ICES-003) as Class B digital devices. To determine which
classification (Class A or B) applies to your computer (or other Dell digital apparatus), examine all
registration labels located on the bottom or the back panel of your computer (or other digital apparatus). A
statement in the form of "IC Class A ICES-3" or "IC Class B ICES-3" will be located on one of these labels.
