7. Maintenance

This section presents procedures for maintaining the Model 4500B.

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

could result in serious injury or death. Service and adjustments should be performed only by

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

corner of the Mother Board Printed Circuit assembly. Both should have a life of 5-10 years. When

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

regulations.
