Attention: This is a Class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to take adequate
measures.
Notice to UK Users
The IBM 3746 Model 900 and IBM 3746 Model 950 are manufactured according to
the International Safety Standard IEC950 and, as such, are approved in the UK
under the General Approval number NS/G/1234/J/100003.
The Active Remote Couplers (ARCs) and the X.21 Interface, housed within the
3746 Model 900 and 3746 Model 950, are approved separately, each having their
own independent approval number. These interface adapters, supplied by IBM, do
not contain excessive voltages. An excessive voltage is one which exceeds 42.4 V
peak ac or 60 V dc. They interface with the 3746 Model 900 or 3746 Model 950,
using Safe Extra Low Voltages only.
In order to maintain the independent approval of the IBM adapters, it is essential
that other optional cards, not supplied by IBM, do not use mains voltages or any
other excessive voltages. Seek advice from a competent engineer before installing
other adapters not supplied by IBM.
Year 2000 Statement
This product is Year 2000 ready. When used in accordance with its associated
documentation, it is capable of correctly processing, providing, and/or receiving
date data within and between the 20th and 21st centuries, provided all other
products (for example, software, hardware, and firmware) used with the product
properly exchange accurate date data with it.
