Operation Notes
Disconnect the Clone from the TV when you are
finished; automatically switching it off. The real-
time clock continues to run when the main circuits
are switched off.
Reset Clone After Static Shock
After replacing exhausted batteries, or if the
programmer behaves strangely after a static
shock, use a paper clip or similar instrument
inserted through the small hole marked ”RESET”
to activate the internal reset switch and restore
normal operation.
After a reset, check the real-time clock setting. It
may be necessary to reset the Clone Programmer
clock from a TV containing the correct time.
The LT2000 programmer is designed to be used
with TVs containing the 221-01006 and later
processors. Use with earlier TV sets
may give unpredictable results. The specific
microprocessor used in any TV set may be
determined by activating the Installer
Menu. The microprocessor part number appears
at the top of the screen when the Installer Menu is
activated. Processors before the 221-01006-04
have a limited screen display capability. They
can not display entire screens as shown in the
quick setup instructions accompanying the
LT2000 clone programmer. Use the printed menu
illustrations on the quick setup sheet supplied
with the Clone as an aid to making your
programming choices. (Although the menus are
not all displayed, the clone functions all operate
normally).
