Notice to United Kingdom Users

The United Kingdom Telecommunications Act 1984

This apparatus is approved under General Approval number

NS/G/1234/J/100003

for indirect connections to public telecommunications systems in the United Kingdom.

It is a condition of approval that the

current drawn

by the total of all

adapter

cards

installed

within

the

Host

environment, together

with

any auxiliary apparatus, does not

exceed the power specification as

stated in the Technical Reference

Material of the host apparatus.

Other usage will invalidate the approval of

this adapter card if as a

result it ceases to comply with safety requirements. The power

requirements

for

the

adapter

are

in

“Specifications”

on

page 1-2.

To maintain the independent approval

of

this

adapter,

it

is

essential

that other optional cards, not supplied by

IBM, do not use mains

voltages

or

any

other

excessive voltages. An

excessive

voltage is

one that exceeds 42.4V peak ac

or 60V dc. If you

have

any doubt,

seek advice from a competent engineer before installing other

adapters

into the Host

apparatus.
