United States
Note: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Properly shielded and grounded cables and connectors must be used in order to meet FCC emission limits.
Proper cables are available from IBM authorized dealers. IBM is not responsible for any radio or
television interference caused by using other than recommended cables or by unauthorized changes or
modifications to this equipment. Unauthorized changes or modifications could void the user's authority to
operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
United Kingdom
Warning: This IBM product is made to high Safety standards. It complies inherently with
Telecommunications safety standard BS6301. It is not designed to provide protection from excessive
voltages appearing externally at its interfaces. Therefore, when this product is connected to a public
telecommunications network via any other equipment, and you connect to this product items not supplied
by IBM United Kingdom Ltd., you must comply with mandatory telecommunications safety requirements.
You may do this either by choosing products which also are approved as complying to BS6301 or British
Telecom Technical Guide No. 26, or by the use of approved safety barriers. Consult the local office of your
public telecommunications operator, for advice and permission to make the connections.
Canadian Department of Communications compliance statement
This equipment does not exceed Class A limits per radio noise emissions for digital apparatus, set out in f
the Radio Interference Regulation of the Canadian Department of Communications. Operation in a
residential area may cause unacceptable interference to radio and TV reception requiring the owner or
operator to take whatever steps are necessary to correct the interference.
Avis de conformite aux normes du ministdre des Communications du Canada
Cet ^quipement ne d^passe pas les limites de Classe A d'^mission de bruits radio^lectriques pour les
appareils num§riques, telles que prescrites par le R§glement sur le brouillage radio^lectrique ^tabli par le
ministers des Communications du Canada. L'exploitation faite en milieu r6sidentiel peut entrainer le
brouillage des receptions radio et t^l6, ce qui obligerait le propri^taire ou l'op6rateur k prendre les
dispositions n6cessaires pour en ^liminer les causes.
