connectors (jacks) to suit standard aviation connections. The EQ-Link system 
will automatically power  ON  when the  aircraft communications  system  is

additional  support.  For  additional  performance  operation  when  multiple  EQ-
Link units are used on one aircraft simply set extra units to SLAVE mode. In 
this  mode all  the  units will  operate  as  one  and not interfere  with  each  other,

Slave mode can be entered by pressing and holding the STATUS button for 4 
seconds,  the  LED  lights  will  then  change  every  2  seconds  from  Master  to 
Slave  and  announce  this  in  the  headset.  When  on  the  desired  mode,  just 
release the button. 
Plug your normal headset into  the  connections on  the EQ  R-Link,  press  and 
hold the ON button for 4 seconds and the EQ R-Link will turn ON. 
NOTE: A typical aircraft can only have one master and up  to 5 slaves in the
