The Miro Key Fob (MKFOB) is a battery powered, Top Dog™ 
enabled remote device, which allows the user to recall and 
record scenes in a Miro wireless network. The key fob can 
be placed on a key-chain or in the included mounting clip 
and attached to a car visor or similar surface. 

The unit has three operating modes. The operating mode 
determines which scenes the MKFOB will execute. It is 
equipped with three buttons so it can execute up to three 
scenes that are recorded using the key fob itself or a Miro 
wireless room or house scene controller. 

The open field operating range between the key fob and 
other Miro wireless devices is 80 feet, but this will vary 
according to the type of construction being used and 
whether there are objects between the user and the devices 
on which the scenes will execute. Since the key fob uses 
radio transmission (as opposed to infrared), line-of-sight is 
not required. 

A typical key fob application is to control house level scenes 
using operating Mode-1. For example:

• Button 

1 turns on a pathway of light in the house

• Button 

2 turns off all except for selected night-lights

• Button 

3 turns off all lights

Another common application is to control house level 
scenes including a “panic” scene using Mode-2. For 
example:

• Button 

1 turns on a pathway of lights in the house

• Button 

2 turns off all lights in the house

• Button 

3 evokes the panic feature (lights on dimmers 

flash and those on switches come on to full bright) 

A less common, but possible application is to control room 
level and house level scenes using Mode-3. For example:

• Button 

1 recalls the lights in a particular room, such as 

the great room

• Button 

2 turns off all, or selected lights in the room

• Button 

3 turns off all, or selected house lights 

These three applications are typical, however the user can 
record scenes in any number of ways. For example, Mode-1 
could be used to have three different arrival scenes (lights 
on) or leaving/night scenes (lights off). Just remember that 
each button can only recall one specific scene as described 
in the Operating Mode sections on the next page. For 
example, house scenes 1, 5, and 11 are the only scenes that 
can be recalled in Mode-1. 

Watt Stopper wireless devices use radio signals to 
communicate with each other to control lighting and other 
types of electric loads in selected areas. These wireless 
devices use the 900MHz band for high-speed control 
communication. Using Watt Stopper “frequency-agile” Top 
Dog™ technology, these wireless devices avoid interference 
with other 900MHz devices, such as cordless phones and 
baby monitors.

The MKFOB functions as part of a network that contains 
Top Dog enabled wireless devices that may include Miro 
architectural or decorator-style in-wall devices as well as 
portable remote controls and other accessories. In order to 
properly operate a key fob you must have at least one room 
or house scene controller installed. (If you want to operate 
the key fob without a scene controller, contact Technical 
Support for additional information.) Prior to using the key 
fob the other devices should be installed and programmed. 

A MKFOB may be added to a Miro or Miro decorator 
wireless installation at any time and there is not any limit 
to the number that can be used. 

Instructions for installation, binding operations, and use 
are included with the relevant wireless devices. Application 
support information and installation guides for Watt 
Stopper/Legrand wireless network devices are available at
