Reset of Microprocessors

In the event that the controls of the C500 stop functioning press and hold the STANDBY/ON Push-button. Three to four seconds later the Front Panel Alphanumeric Display will indicate “DETECT SYSTEM”; at this point release the STANDBY/ON Push-button. This will reset the C500 microprocessors. Refer to figure 85.

Figure 85

Note: The above condition is usually caused by either interruptions in AC power and/or major changes in voltage.

Configuration Change

When a change is made to a C500 System (Controller and Preamplifier) by changing the current Preamplifier type (C500P or C500T) , the Front Panel Alphanumeric Display will indicate “CONFIG CHANGE” and the LED indicators above the SETUP and REC MONITOR Push-buttons will be flashing. Refer to figures 86

and 87. If there is not to be any

changes to the C500 System, but rather reconnecting a

Preamplifier that was previ- ously connected to the C500 Controller perform the follow- ing:

Figure 87

1.Remove the AC Power Cord from the Rear Panel of the C500 Controller.

2.Reconnect the previously connected Preamplifier.

3.Reattach the AC Power Cord.

4.The C500 System will automatically reset itself and will retain any changes that where previously made in the SETUP Mode.

If the change to the C500 System is a result of changing Preamplifier Types (C500P or C500T) then perform the fol- lowing steps:

1.Remove the AC Power Cord from the Rear Panel of C500 Controller.

2.Connected the Preamplifier(s) to the C500 Controller.

3.Reteach the AC Power Cord.

4.Press and hold the SETUP and REC MONITOR Front Panel Push-buttons until the Alphanumeric Display in- dicates “DETECT SYSTEM”, then release the two Push-buttons. At this point several messages will ap- pear on the Alphanumeric Display depending on the C500 System makeup. Refer to figures 88 thru 91.
