IntroductionVoltage Regulator WarningDo not plug this machine into ANY voltage regulating device. Contact Panoramic Corporation with anyquestions regarding this.X-ray Shielding RequirementsThe requirements for panoramic and cephalometric shielding for building, operator, and patient, dependon 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 theseregulations.6 Copyright 2008 Panoramic Corporation
Pre-Installation CheckElectrical RequirementsOptimally, the PC-1000 and the PC-1000/Laser 1000 should have a dedicated 105-125 VAC, 20 A circuitwith line regulation of 5% or better. If a dedicated circuit is not available, a regular 20 A circuit will workas long as it is not taxed by other loads beyond 5 A. A standard 115 VAC, three-wire, grounded, electricaloutlet should be installed by an electrician behind the machine.Control Panel OrientationThe control panel on the PC-1000 and the PC-1000/Laser 1000 is mounted directly on the side of themachine and requires no separate installation, wiring, or mounting. Although the control panel is mountedon 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 OrientationThe cephalometric arm for the PC-1000/Laser 1000 is shipped in a separate box and can be mounted oneither side of the machine. Verify with the doctor on which side the cephalometric arm should be located.Remote SwitchSome states and local governments require that the exposure switch to be remotely installed. A remoteswitch kit is available from Panoramic Corporation. Refer to Appendix G for detailed procedures.Darkroom RequirementsProper darkroom facilities must be present before installing the PC-1000 or PC-1000/Laser 1000. Thedarkroom will be used to process test films at the time of installation to verify proper calibration. Refer toAppendix A for darkroom requirements and processing procedures.
