The Optional Expander
You can use the Unifier as you would your other 
remote controls. It transmits very powerful line-of-sight 
output using infrared light commands (invisible to the 
naked eye). When you point the Unifier at the 
components, expect the range to be between 30 and 
50 feet. When the remote is not pointed in the general 
direction of the components, the range will vary 
(depending on reflective surfaces, lighting, etc.). 
However, the Unifier also sends radio signals in 
every direction. By purchasing the optional Expander 
(a radio receiver), you can operate your equipment 
with the Unifier 50 to 100 feet away (through walls, 
doors, cabinets, inside or outside). Since the 
Expander picks up the Unifier's radio signals from 
any direction, regardless of distance, the Unifier 
doesn’t have to be pointed!
Nothing has to be done to the Unifier for this 
feature to work. Every time you press a button on the 
Unifier, it sends both a standard infrared command 
AND a radio signal. If you install the Expander kit, the 
MRF-100 will receive the Unifier’s radio signals and 
translate them into the infrared commands that control 
your components.
Note: The Unifier's radio signals will not control 
components directly. You must have an Expander to 
receive the Unifier's radio signals. Components 
that came with "no pointing" radio remote controls cannot
be operated by the Unifier unless the component can 
be switched to standard infrared control via its internal 
menus. Some remote control ceiling fans are radio only and 
cannot be operated by the Unifier.
