DIAGNOSTIC PROCEDURES

This product can be easily measured for maintenance using a Communications Service Monitor, of which several models are available. A typical test configuration for the ORION product is shown in Figure 5. It is also

possible to combine this test configuration with the PC Programming configuration shown in Figures 2 and 3. This usually results in increased efficiency, since the service technician can alternate between programming and hardware testing, as the need arises.
