Information to User
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of 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 interference in which case the user
will be required to correct the interference at his own expense.
NCR is not responsible for any radio or television interference caused by unauthorized
modification of this equipment or the substitution or attachment of connecting cables
and equipment other than those specified by NCR. The correction of interference
caused by such unauthorized modification, substitution or attachment will be the
responsibility of the user. The user is cautioned that changes or modifications not
expressly approved by NCR may void the user’s authority to operate the equipment.
Canadian Department of Communications
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus 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 la classe A prescrites dans le
Règlement sur le brouillage radioélectriques édicté par le ministrère des
Communications du Canada.

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.
Chapter 1: Product Overview
Introduction
The NCR 7452 Workstation is based on standard PC technology and is
designed to satisfy the needs of the department store, mass
merchandise, and food distribution retail markets.
The workstation features a Series 4000 Pentium III or Celeron 64-Bit
686, or 32-Bit 586 Motherboard with APM compatible BIOS. The power
management strategy is developed around the Intel/Microsoft
Advanced Power Management (APM) specification.
Note: Class 1xxx and Class 2xxx workstations contain 586 and 686
processors respectively. The Class 35xx contains a 686 Motherboard
with an on-board VGA LCD port. The Series 4xxx workstations contain
Pentium III or Celeron processors.
Note: Workstations equipped with 586 and 686 processors are
designated by "Class" (i.e., Class 1xxx, 2xxx, 3xxx and 35xx). The
Pentium III and Celeron processors are designated by "Series" (i.e.,
Series 4xxx).
1-2 Chapter 1: Product Overview
The following table shows the 7452 major models and the CPUs
available for those models.
7452 Major Model CPU
7452-1xxx 486
7452-2xxx 686-100 MHz
7452-5xxx
(Japan only)
586-133 MHz
7452-3xxx 686-100, 166, 233 MHz
7452-35xx 686-233, 333, 400 MHz
7452 -4xxx Celeron, PIII (433+ MHz)
A riser board is available for the Motherboard to accommodate four
industry standard expansion slots (2 AT, 1 PCI and 1 shared AT/PCI),
and 32KB (standard) or 128KB (option) of battery backed CMOS static
memory. A riser board with no CMOS memory is also available with
the new Series 4000.
The workstation has three auxiliary power ports for peripherals such
as customer displays and 5944 EFT devices. A fourth auxiliary power
port is available to power a printer, thus eliminating the need for
external power supplies and simplifying cable routing.
Uninterruptible Power Supply (UPS) protection is provided through a
new power supply with internal UPS functionality.
The 7452 uses the Retail TAPS software on DOS and Win 3.x, and
OPOS on Windows 95, Windows 2000, and Windows NT.
