3.1

 

Site Planning

 

The  Ears hardware,  like most electronic equipment, should not be subject to harsh environmental 
conditions. To assure ease  of  servicing and reliable  operation, several  f actors must be considered when 
planning the system installation. Always consider the f ollowing BEFORE install the  Ears  unit: 

 

 

The  CE certif ied Ears DC power adapter operates on 100  to 240  Vac, as such, an appropriate 

receptacle compliant with local electrical codes must be provided within 6 f eet of  the Ears. 

 

For continued reliable  operation, attempt to mitigate sudden power loss by perf orming the 
shutdown procedure in 2.7 above. Repeated sudden power loss could potentially result in f lash 

memory corruption requiring  the unit to be repaired. 

 

The  Ears hardware  should be in a well-ventilated  area  heaving a temperature  range  of  -40 to 70 
degrees C, and a humidity range  of  5 to 95% (non-condensing). 

 

Accessibility of the Ears f or servicing. 

 

Protection f rom f looding, flammable materials, excessive dust and vibration. 

 

3.2

 

Unpacking the Ears Components

 

Included  with  the  Ears  is the  device itself  and  the  AC  to 12V  DC Converter  with  Power  Cord. Audio 
inputs and  network cables are  standard cables and as such should be cut to length  upon installation. 
Upon request,  a  Console Cable  can  be  purchased f rom Exacom, Inc.  to allow  serial  communication 
f rom the device to a PC.

The  f ront of  the Ears unit  primarily consists of  indicators to help monitor the state of  the device as it is 
operating. 

OLED  Display 

– Publishes information about the device using a graphical display  

 

CTRL  Push  Button 

– Allows the user to alternate displays as well as power of f the device
