7.1 Safety
Although the 4500B has been designed in accordance with international safety standards, general
safety precautions must be observed during all phases of operation and maintenance. Failure to
comply with the precautions listed in the Safety Summary located in the front of this manual

qualified service personnel.
7.2 Cleaning
Painted surfaces can be cleaned with a commercial spray-type window cleaner or a mild detergent and water solution.
CAUTION
When cleaning the instrument, do not allow cleaning fluid to enter the fan intake and exhaust
vents. Avoid using chemical cleaning agents which can damage painted or plastic surfaces.
7.3 Inspection
If the Model 4500B malfunctions, perform a visual inspection of the instrument. Inspect for signs
of damage caused by excessive shock, vibration or overheating. Inspect for broken wires, loose
electrical connections, or accumulations of dust or other foreign matter.
Correct any problems you discover and conduct a performance test to verify that the instrument is
operational. (See section 7.5 Performance Verification). If the malfunction persists of the
instrument fails the performance verification, contact Boonton Electronics for service.
7.4 Lithium Batteries
The 4500B contains two coin cell Lithium batteries to provide for memory storage of start-up
information. One is located on the Single Board Computer and the other on the topside left front

replacement is necessary, they must be disposed of in strict compliance with local environmental
regulations.
