Purpose
Panoramic Corporation provides this printed manual as a guide for the operation of the PC-1000 dental
panoramic X-ray machine and the PC-1000/Laser 1000 dental panoramic/cephalometric dental X-ray
machine.
The PC-1000 will enable the user to take panoramic X-ray images. The PC-1000/Laser 1000 will enable
the user to take panoramic X-ray images, as well as cephalometric X-ray images. A laser alignment
device is incorporated into the PC-1000/Laser 1000.
The information contained in this manual is not all inclusive and Panoramic Corporation should be
contacted for assistance and clarification when necessary.
It is imperative that this equipment be installed, serviced, and used by personnel familiar with the
precautions required to prevent excessive exposure to both primary and secondary radiation. This
equipment features protective designs for limiting both the primary and secondary radiation produced
by the X-ray beam. However, design features cannot prevent carelessness, negligence, or lack of
knowledge.
Only personnel authorized by Panoramic Corporation are qualified to install and service this equipment.
Any attempt to install or service this equipment by anyone not so authorized will void the warranty.

Introduction
Voltage Regulator Warning
Do not plug this machine into ANY voltage regulating device. Contact Panoramic Corporation with any
questions regarding this.
X-ray Shielding Requirements
The requirements for panoramic and cephalometric shielding for building, operator, and patient, depend
on state and local regulations. Contact your state Department of Health for compliance information.
Compliance could involve a blueprint review, facility check, wall construction, film badge implementation,
remote switch installation, and/or a lead apron. It is beyond the scope of this manual to advise on these
regulations.

Pre-Installation Check
Electrical Requirements
Optimally, the PC-1000 and the PC-1000/Laser 1000 should have a dedicated 105-125 VAC, 20Acircuit
with line regulation of 5% or better. If a dedicated circuit is not available, a regular 20 A circuit will work
as long as it is not taxed by other loads beyond 5 A. A standard 115 VAC, three-wire, grounded, electrical
outlet should be installed by an electrician behind the machine.
Control Panel Orientation
The control panel on the PC-1000 and the PC-1000/Laser 1000 is mounted directly on the side of the
machine and requires no separate installation, wiring, or mounting. Although the control panel is mounted
on the patient's left side from the factory, it can be easily relocated to the opposite side during installation.
Verify with the doctor on which side the control panel should be located.
Cephalometric Arm Orientation
The cephalometric arm for the PC-1000/Laser 1000 is shipped in a separate box and can be mounted on
either side of the machine. Verify with the doctor on which side the cephalometric arm should be located.
Remote Switch
Some states and local governments require that the exposure switch to be remotely installed. A remote
switch kit is available from Panoramic Corporation. Refer to Appendix G for detailed procedures.
Darkroom Requirements
Proper darkroom facilities must be present before installing the PC-1000 or PC-1000/Laser 1000. The
darkroom will be used to process test films at the time of installation to verify proper calibration. Refer to
Appendix A for darkroom requirements and processing procedures.
