MODEL
28ADJ
Adjustable Attenuator — 10kΩ
INSTALLATION INSTRUCTIONS
DESCRIPTION
The 28ADJ Adjustable Emitter Attenuator is an in-line device that connects
between a connecting block and an IR emitter. Featuring a flexible Short (0
Ohm) to 10kOhm attenuation selection, the 28ADJ can adjust an emitter’s
output strength to improve complex IR system compatibility. A plug-anduse connector makes installation fast and quick.
INSTALLATION
• Turn the adjustment clockwise, fully. This will set the attenuation to
zero which is exactly how the emitter will perform without a 28ADJ
attached.
• Connect the 28ADJ to the Emitter output port on the connecting block.
• Next, connect the Emitter to the 28ADJ and place the Emitter over the
source equipment’s control eye. In some cases it may be difficult to
find the location of the IR sensor on the component. Consult the
owner’s manual of the unit, or the manufacturer, for the exact IR
sensor window location.
• Direct a remote control towards the IR receiver. Be sure the IR
system has power and an IR receiver connected to the connecting
block.
• Now slowly attenuate the emitter’s output strength by turning the
adjustment counter-clockwise. This will reduce IR emitter strength.
While turning the adjustment, use a remote control until it the
commands sent can control the equipment.
