Figure 4 – The Model MRC88 Keypad – Front Panel Features and Functions 

 

MRC88 KEYPAD - FRONT FEATURES: 
1. MRC88 

Keypad. 

 
2. Power. 

 

Turns the zone ON and OFF. Can be programmed with IR codes or sequences. 

 

3. IR 

Sensor. 

Receives IR from hand-held remotes to control both source components and the MRC88 

system. A Programmable Learning Remote such as the Xantech URC2 is recommended for integrating the 
IR commands of the MRC88 and source components into a single controller. Compatible with most brands 
of remote controls, though some may not be programmable and will therefore only control the source 
components. 

 

4.  Status Indicator LED

. Will indicate zone/system status and will flash as IR is received at the IR Sensor. 

These indicators, one for each Keypad, provide the following Information: 
a)  LED Off = Zone OFF 
b)  Steady Green = Zone ON 
c)  Slow Green Blink = Zone MUTE
