Download C.A.S. - Analyzer

8.2 Operational Troubleshooting
8.2.1
Introducing Remarks
The C.A.S. Analyzer can log all error messages and fixes to a printer or a connected PC. Even
if you do not want to use this feature, it may be useful to have a PC (for example, a laptop) at
hand in order to be able to locate the reason of an error if necessary. For more information on
how to proceed, refer to chapter 7.8.2 „Printer/Computer Logging“.
An error analysis on the exclusive basis of the front-panel error indicators is difficult to perform (especially in case of speaker failure). We therefore recommend the use of a PC or a
printer.

identical to the actual mains voltage.
Check whether the C.A.S. Analyzer is properly connected to the mains.
Check the mains fuse and replace it as explained in chapter 9.1 „Inside Servicing“ if

Troubleshooting
If using the DCF77 receiver, move the active antenna to a position with better reception
and align it to the appropriate sender direction. Afterwards, temporarily disconnect the
Analyzer from the mains, then reconnect it. If a time signal can be received, the INT ERR
error indicator should go dark after approximately three minutes (unless there are more
malfunctions). It is possible that multiple attempts must be performed in order to find the
optimum antenna setting.
