[Elecraft] K3 power loss: Last settings forgotten

[Ron D'Eau Claire]

Following Eric's report of having his KAT3 "hang" in a strange state after
powering down without first pushing the K3 POWER button, I queried Wayne
about how this could happen.

He pointed out that can be the case if an EEPROM write operation happens to
be in progress when the power is removed. He said it's "rare" but possible
and recommends *always* pushing the POWER button to shut down the K3 before
removing the DC power to avoid problems.

The original query about losing last settings is covered explicitly in the
Owner's manual (page 13).
