having read the manual, to trigger a remote switch, you jsut have to short the pin to ground. 
however im wanting to create a remote control, which will have LED's on it, which will light when a switch is pressed. the electronics to do this im happy with, but this would also result in connecting the remote pin, through a battery (say, 3volts), through the led, through the switch and back into ground. 
  
would putting a battery in the connection damage the desk, or have any effect on the operation of the remote switch? 
  
thanks, 
matt
