If you are having problems with your DC205 you can call us at
If you wish to try and fix the problem yourself, the user manual may be useful, and the following troubleshooting guide may be helpful too.
1) Instrument is unresponsive to front-panel button presses
Try a power-up reset. Turn the power off, then while holding the backspace key (left arrow key) down, turn the power back on. After two seconds release the backspace key. The unit will dsiplay the message "dEF CFG" to indicate the default configuration is being restored. If this doesn't correct the problem the instrument will need to come back to SRS for service.
