About the Modem
This equipment complies with Part 68 of FCC rules. On the bottom of this
equipment is a label that contains, among other information, the FCC registration
number and ringer equivalence number (REN) for this equipment. If requested,
this information must be provided to the telephone company.
The modem jack of this equipment complies with Sub-part F of Part 68 of FCC
rules.
The 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 REN for the calling areas.
If the terminal equipment 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 isn't 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 necessary.
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.
If trouble is experienced with this equipment, please contact Sharp Electronics
Corp. for repair and (or) warranty information (Refer to the end of this section). If
the trouble is causing harm to the telephone network, the telephone company may
request you remove the equipment from the network until the problem is resolved.
The 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.)

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person
to use a computer or other electronic device, including fax machines, to send any
message unless such 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 the sending machine or such business,
other entity, or individual. (The telephone number provided may not be a 900
number or any other number for which charges exceed local or long-distance
transmission charges.) To program this information, refer to the manual of the
communication software.

Notice for Users in the UK and Ireland
The mains lead of this product is fitted with a non-rewireable (moulded) plug
incorporating a 3A fuse. Should the fuse need to be replaced, a BSI or ASTA
approved BS 1362 fuse marked
also indicated on the pin face of the plug must be used.
Always refit the fuse cover after replacing the fuse. Never use the plug without the
fuse cover fitted.
In the unlikely event of the socket outlet in your home not being compatible with
the plug supplied, cut-off the mains plug and fit an appropriate type.
DANGER:
The fuse from the cut-off plug should be removed and the cut-off plug destroyed
immediately and disposed of in a safe manner.
Under no circumstances should the cut-off plug be inserted elsewhere into a 13A
socket outlet as a serious electric shock may occur.
To fit an appropriate plug to the mains lead, follow the instructions below:
IMPORTANT:
The wires in the mains lead are coloured in accordance with the following code:
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this product may not correspond
or and of the same rating as above; which is
with the coloured markings identifying the terminals in your plug, proceed as
follows:
• The wire which is coloured blue must be connected to the plug terminal which is
marked N or coloured black.
• The wire which is coloured brown must be connected to the plug terminal which
is marked L or coloured red.
Ensure that neither the brown nor the blue wire is connected to the earth terminal in
your three pin plug.
Before replacing the plug cover, make sure that:
• If the new fitted plug contains a fuse, Its value is the same as that removed from
the cut-off plug.
• The cord grip is clamped over the sheath of the mains lead and not simply over
the lead wires.
