Troubleshooting Guide
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.
