Telephone company procedures
The goal of the telephone company is to provide you with the best service it
can. In order to do this, it may occasionally be necessary for them to make
changes in their equipment, operations, or procedures. If these changes
might affect your service or the operation of your equipment, the telephone
company will give you notice in writing to allow you to make any changes
necessary to maintain uninterrupted service.
If problems arise
If any of your telephone equipment is not operating properly, you should
immediately remove it from your telephone line, as it may cause harm to
the telephone network. If the telephone company notes a problem, they
may temporarily discontinue service. When practical, they 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. In the event repairs are ever needed on your
modem, they should be performed by TOSHIBA Corporation or an
authorized representative of TOSHIBA Corporation.

Notes for Users in Australia and New Zealand
Modem warning notice for Australia
Modems connected to the Australian telecoms network must have a valid
Austel permit. This modem has been designed to specifically configure to
ensure compliance with Austel standards when the country/region selection
is set to Australia. The use of other country/region setting while the modem
is attached to the Australian PSTN would result in you modem being
operated in a non-compliant manner. To verify that the country/region is
correctly set, enter the command ATI9 which displays the currently active
setting.
To set the country/region permanently to Australia, enter the following
command sequence:
AT+GCI=09
Failure to set the modem to the Australia country/region setting as shown
above will result in the modem being operated in a non-compliant manner.
Consequently, there would be no permit in force for this equipment and the
Telecoms Act 1991 prescribes a penalty of $12,000 for the connection of
non-permitted equipment.
Notes for use of this device in New Zealand
■ The grant of a Telepermit for a device in no way indicates Telecom
acceptance of responsibility for the correct operation of that device
under all operating conditions. In particular the higher speeds at which
this modem is capable of operating depend on a specific network
implementation which is only one of many ways of delivering high
quality voice telephony to customers. Failure to operate should not be
reported as a fault to Telecom.
■ In addition to satisfactory line conditions a modem can only work
properly if:
a/ it is compatible with the modem at the other end of the call and
b/ the application using the modem is compatible with the application
at the other end of the call - e.g., accessing the Internet requires
suitable software in addition to a modem.
■ This equipment shall not be used in any manner which could constitute
a nuisance to other Telecom customers.
■ Some parameters required for compliance with Telecom’s PTC
Specifications are dependent on the equipment (PC) associated with
this modem. The associated equipment shall be set to operate within
the following limits for compliance with Telecom Specifications:
a/ There shall be no more than 10 call attempts to the same number
within any 30 minute period for any single manual call initiation, and
b/ The equipment shall go on-hook for a period of not less than 30
seconds between the end of one attempt and the beginning of the
next.
c/ Automatic calls to different numbers shall be not less than 5
seconds apart.

Because Wireless LAN products operate within the guidelines found in
radio frequency safety standards and recommendations, TOSHIBA
believes Wireless LAN is safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and
result from deliberations of panels and committees of scientists who
continually review and interpret the extensive research literature.
In some situations or environments, the use of Wireless LAN may be
restricted by the proprietor of the building or responsible representatives of
the organisation. These situations may for example include:
■ Using the Wireless LAN equipment on board of aeroplanes, or
■ In any other environment where the risk of interference to other devices
or services is perceived or identified as harmful.
If you are uncertain of the policy that applies on the use of wireless devices
in a specific organisation or environment (e.g. airports), you are
encouraged to ask for authorisation to use the Wireless LAN device prior to
turning on the equipment.
