If desired, the three LED indicators on the front of the radiator can be disabled using this switch. Set this
switch to the position towards the left side of the rear of the radiator to disable the LED indicators.
To enable the LED indicators set this switch to the position towards the right side of the rear of the radiator.

Set Delay Compensation Switch
5A
The position of the delay compensation switch does not matter in single radiator systems.
Single Radiator Systems
5B
It is necessary to select the correct delay compensation switch
setting for each radiator to ensure that each radiator transmits
the same signal at exactly the same time in an overlapping
,multiple radiator system. Not setting the delay compensation
switch correctly will result in reduced coverage area for the
system. See design guide page 16 for determining the correct
delay compensation switch setting for each radiator in a multiple
radiator system.
