Adjustment of output level in remote receiver
To be sure that signals from remote control
repeater arrive at their destination, infrared receiver
has an amplifier built in which can adjust the level.
As any other amplifier it can cause distortions
in signals if level is excessive or not arrive at
destination if it’s weak.
How to decide which is the suitable level is
complicated and should need right tools to exactly
measure what’s happening.
For a correct adjustment of this level consider the
following:
1st Function of remote control repeater must
perfectly work if line is direct from Multivision to remote room. If there are more
devices signal will be weaker (arriving to cancel the signal)
2nd It should not appear interferences in TV when this function is used.
Depending on adjusted level some horizontal lines could appear in the picture, in
this case adjust output level with a small screwdriver turning on the left the
adjusting potentiometer of infrared receiver IR 3 until they disappear but the
repeater is functioning.
Check that repeater works correctly with all remote controls that you are going to
use.
Anyway you must know that with factory default adjustment it should work without
problems if installation is conventional.
