[Elecraft] W2 wattmeter lock-up

[JOE]

I had a situation where the W2 watt meter would flash the LEDs on power 
up, then I was not able to communicate with it via the RS232 cable.  
After repeated attempts, I was able to quickly press the LED on/off 
button on the software during power up to make it come back to life.  I 
had to press this button during the power up cycle or the W2 would not 
respond.  Evidently the LED button got pushed by accident, but it put 
the W2 in an inoperable mode that required a site visit to our remote 
base location.

Has anyone else experienced this?  Probably most people never use this 
feature.
