1) Instrument is unresponsive to front-panel button presses
Try a power-up reset. Turn the power off, then while holding the Left Arrow (backspace) key down, turn the power back on. After two seconds release the Left Arrow (backspace) key. If this doesn't correct the problem the instrument will need to come back to SRS for service. Click here to get an RMA number.
