13. UNIT DIAGNOSTIC TESTS
This unit has eight built-in diagnostic tests which check it for proper
performance. Although the tests are designed primarily for use by the
service technician, they can also be executed by the user to identify
defective components. However, never attempt to check inside the
unit; there are no user-serviceable parts inside. Any repair work is
best left to a qualified technician.
