FCC CLASS A
FCC Compliance Statement
For American Users
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.
WARNING
The connection of a non-shielded printer interface cable to this printer will invalidate
the FCC Verification of this device and may cause interference levels which exceed
the limits established by the FCC for this equipment.
You are cautioned that changes or modifications not expressly approved by the
party responsible for compliance could void your authority to operate the
equipment.
FOR CANADIAN USERS
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus as set out in the radio interference regulations of the
Canadian Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de Class A prescrites dans le règlement
sur le brouillage radioélectrique édicté par le Ministère des Communications du
Canada.
GERÄUSCHPEGEL
Gemäß der Dritten Verordnung zum Gerätesicherheitsgesetz
(Maschinenlärminformations- Verordnung-3. GSGV) ist der arbeitsplatzbezogene
Geräusch-Emissionswert kleiner als 70 dB(A) (basierend auf ISO 7779).

TM-U950
Follow the procedures below only when you use the printer as a
single unit (not connected to an intelligent module). When you use
the printer with the intelligent module, see the IM-403/405 User's
Guide for details.
You need an appropriate serial interface cable to connect your
computer to the printer's built-in interface.
1. Make sure that both the printer and computer are turned off;
then attach the cable connector securely into the printer's
interface connector.
Setting Up the Printer 1-3
2. Tighten the screws on both sides of the cable connector.
Note:
Your printer comes with inch-type hexagonal lock screws
installed. To use an interface cable that requires millimeter-type
screws, replace the inch-type screws with the enclosed
millimeter-type screws using a hex screwdriver (5 mm).
To distinguish the two types of screws, see the figure below. The
inch-type screw is on the left.
3. Attach the other end of the cable to the computer.
4. Plug the power supply's power cord into an electrical outlet.
