Dangerous Procedure Warnings
Warnings, such as the example below, precede potentially dangerous procedures throughout this
manual. Instructions contained in the warnings must be followed.
Section 1-6EMC, EMI, and ESD
1-6-1
Electromagnetic Compatibility
Electro Magnetic Compatibility describes a level of performance of a device within its electromagnetic
environment. This environment consists of the device itself and its surroundings including other
equipment, power sources and persons with which the device must interface. Inadequate compatibility
results when a susceptible device fails to perform as intended due interface from its environment or
when the device produces unacceptable levels of emission to its environment. This interference is often
referred to as radio-frequency or electromagnetic interface (RFI/EMI) and can be radiated through
space or conducted over interconnecting power of signal cables. In addition to electromagnetic energy,
EMC also includes possible effects from electrical fields, magnetic fields, electrostatic discharge and
disturbances in the electrical power supply.
1-6-2
Electrostatic Discharge (ESD) Prevention
1-6-3
CE Compliance
The LOGIQ A3 unit conforms to all applicable conducted and radiated emission limits and immunity
from electrostatic discharge, radiated and conducted RF fields, magnetic fields and power line transient
requirements.
Applicable standards are: 47CFR Part18, IEC/EN 60601-1-2
NOTE:
For CE Compliance, it is critical that all covers, screws, shielding, gaskets, mesh, clamps, are
in good condition, installed tightly without skew or stress. Proper installation following all
comments noted in this service manual is required in order to achieve full EMC performance.
DANGEROUS VOLTAGES, CAPABLE OF CAUSING DEATH, ARE PRESENT IN
THIS EQUIPMENT. USE EXTREME CAUTION WHEN HANDLING, TESTING AND
ADJUSTING.
EXPLOSION WARNING: DO NOT OPERATE THE EQUIPMENT IN AN EXPLOSIVE
ATMOSPHERE. OPERATION OF ANY ELECTRICAL EQUIPMENT IN SUCH AN
ENVIRONMENT CONSTITUTES A DEFINITE SAFETY HAZARD.
DO NOT SUBSTITUTE PARTS OR MODIFY EQUIPMENT: BECAUSE OF THE DANGER
OF INTERDICTING ADDITIONAL HAZARDS, DO NOT INSTALL SUBSTITUTE PARTS OR
PERFORM ANY UNAUTHORIZED MODIFICATION OF THE EQUIPMENT.
DO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING THE
NECESSARY ESD PRECAUTIONS:
1.)
Always connect yourself, via an arm-wrist strap, to the advised ESD
connection point located on the rear of the scanner (to the right of the
power connector).
2.)
Follow general guide lined for handling of electrostatic sensitive
equipment.
