To set up a master TV you will need to know
how to enter the 20LH1DC1 Installer menu
and make changes to the default values as
required. If necessary, familiarize yourself with
the 20LH1DC1 Installer menu and how to make and
save changes in the menu, beforeattempting to clone
the 20LH1DC1 Master TV setup.
You will also need an Installer remote controlsimilar to
the one shown in the front of this manual.
Finally, the TV’s closable features need to be set up.
This is a critical step. If the Master TV display panel’s
closable features like adding channel icons or channel
labels are not correctly added, then the cloned
20LH1DC1s TVs will all have problems.
As the cloning procedure is being performed, specific
steps need to be done at the indicated times to achieve
the desired result. Be sure to do each task as indicated.
If a procedure or step is left out or not performed
completely, cloning may not work. At each step, pay
attention to assure the TV screen shows the proper
message when cloning. If the message indicated does
not appear, there is a problem with that step and
cloning may not be successful. Cloning is only possible
when the signal source is an Analog channel, not a
digital channel.
