running profile. Some parameters in the Profile Status Menu
can be changed for the currently running profile, but should
only be changed by knowledgeable personnel and with cau-
tion. Changing parameters via the Profile Status Menu will
not change the stored profile but will have an immediate im-
pact on the profile that is running.

Note:
Avoid continuous writes within loops. Excessive writes to
EEPROM will cause premature EEPROM failure. The EE-
PROM is rated for 1,000,000 writes. (To disable EEPROM
writes, go to the Setup Page and then the [Com] menu.
Proceed to the [`nU;s] prompt and set it to no for [Com]
1, 2 or both.)
