feature or to disable it completely perform the
following steps during power up:
1) Turn off the LC100.
2) Hold the key down firmly.
3) Turn on the LC100.
4) After power up, wait about 1 second and
release the key.

time the battery save feature is set for (off to
30 minutes).
6) Using the knob, set the desired time (off to
30 minutes).

return the unit to normal mode. The stored
value will remain in memory until changed by
the operator.
