CHAPTER 5

BASIC LEVEL CHECKS AND SELF TESTS

Before you perform basic troubleshooting and self tests on an i860 unit, determine if any special conditions could affect testing and check the units for defective parts.

There are five categories of basic tests:

Preventive maintenance

Mechanical/electrical checks

Troubleshooting

Self tests

Technician tests

Test procedures are listed in the order in which they should be implemented. Each test contains a description of what it does and the approximate time needed to perform it. For your convenience, a checklist is included that can be used to ensure that all the necessary tests are conducted.

5.1Customer Care

It is sometimes helpful to contact your regional Customer Care representative to determine if the customer has service or billing issues or is known to be using the unit in a poorly covered area. The representative also can inform you if there are system outages or known unit defects.

5.2Test Conditions

During testing, ensure the following antenna conditions are adhered to. Reset conditions can be comparatively difficult to diagnose.

5.2.1Antenna Condition

For intermittent or no transmit problems, ensure the antenna stays fully extended or fully collapsed at all times, never partially extended. If the antenna is loose or collapses halfway down, the unit can lose up to 20 dB of radiated power.

5.2.2Reset Condition

A reset condition can be the most difficult failure to duplicate because a reset can be caused by software, hardware, system, accessory, and coverage problems. A severe hardware failure usually can be detected immediately.
