warranty is valid for a period of one year from the date of
purchase.

This product and all accessories are subject to change, in

After-Sales Service
If Problems Occur
Before requesting service, read the
“Troubleshooting” section in this manual.
If the problem still persists, contact one of the
numbers listed in “Repairs” on the back of this
manual.
If the Result of Inquiries Indicates That a
Repair Is Required
Take your FOMA terminal to a service center
designated by DoCoMo. Be sure to check the
operating hours of the service center. You must
present the warranty.
■
In the warranty period
• The FOMA terminal will be repaired at no charge
subject to the conditions of the warranty.
• The warranty must be presented to receive warranty
service.
The subscriber will be charged for the repair of items
not covered in the warranty or repairs of defects
resulting from misuse, accident or neglect even during
the warranty period.
• The subscriber is charged even during the warranty
period for the repair of failures caused by the use of
devices or consumable items that are not DoCoMo-
specified.
■
Repairs may not be possible in the following
cases
• Repair is not possible when corrosion due exposure to
moisture, condensation or perspiration is detected in a
moisture seal reaction or test, or if any of the internal
boards are damaged or deformed. Since these
conditions are outside the scope of the warranty, any
repairs, if at all possible, will be charged.
■
After expiration of the warranty
• All repairs that are requested are charged.
■
Replacement parts
• Basically, replacement parts (parts required to maintain
product function) will be kept in stock for at least 6
years after termination of production. Please note that
the product may not be repaired even during this
period, depending on the malfunctioning parts due to a
shortage of those parts. Depending on the nature of the
required repairs, it may still be possible to repair your
terminal even after this period. Contact “Repairs” listed
on the back of this manual.
Notes
•
Do not modify the FOMA terminal, the UIM or its
accessories.
- Fire, injury or damage may result.
- In order to prevent interference of radio waves or
network breakdown, the FOMA terminal and the FOMA
card are manufactured according to technical standards
stipulated by law. Do not use FOMA terminals or UIMs
that do not meet these standards.
- If the FOMA terminal is modified (part replacement,
modification, painting, etc.), it will be repaired only after
the modified parts have been restored to the condition at
the time of purchase. However, repair may be refused
depending on the nature of modification.
- Repair of failures or damage caused by modification are
charged even during the warranty period.
•
Do not remove any inscription stickers attached to the
FOMA terminal. The inscription stickers certify that the
FOMA terminal satisfies specific technical standards. If
stickers are removed intentionally or are reattached in
such a way that confirmation of the sticker’s contents is
impossible, repair or servicing may be refused because
confirmation of whether or not the device conforms to
relevant technical standards cannot be made.
•
The ON/OFF function settings and stored data may be
cleared (reset) by failure, repair or handling processes.
Should this happen, configure the functions again.
•
If the device has become wet or moist, bring it to a
DoCoMo repair shop promptly. Depending on the
condition of the device, repair may not be possible.
