Installation Guide & User Instructions 

Operation

With two belt packs, two headsets and a power supply all plugged together 
you are ready to go.  With the MIC ON button illuminated (yellow), the 
microphone on the headset is live and all other users can hear what is said. 
Press   the   MIC   ON   button   again,   and   the   light   will   go   out.     The 
microphone is now muted and no-one can hear you, although you can still 
hear everyone else (as long as their microphones are on).  The LEVEL 
control adjusts the volume of the headset, but does not effect what others 
hear.
Press the CALL button, and the blue LED illuminates not only on your 
belt pack but on all the others in the system as well.  This can be used to 
attract attention.
The headphone amplifier in the RCom is stereo, and can be used with 
stereo headphones.  A stereo sound source can be mixed with the sound 
you hear by plugging it into the AUX socket (stereo mini-jack).  This can 
be useful when operating a sound desk, for example.  In this situation, the 
sound from the com system can be panned to one side to make it easier to 
distinguish sound sources (see the Configuration section).  The LEVEL 
control does not affect the level from the AUX jack - please ensure there is 
a level control on the source (such as the headphone output from a mixing 
console).
