...as easy to use as a 
cable remote switch:

plug the receiver into the remote
control terminal of your camera

turn the receiver ‘ON’

grab the remote control key fob
and you’re ready to go…

• Two-Button operation acts like the two-stage shutter button of your camera:
• Button one (‘halfway pressing’): Activates the auto focus (AF) and automatic exposure (AE) mechanism.
• Button two (‘full pressing’): Releases the shutter and shoots.
  
• You can either hold the AF/AE button to keep the setting while pressing the shutter button -or- just press the shutter button for immediate AF/AE and shutter function.

• The third button of the ZS-2 model has a locking function:
  • One press releases the shutter and keeps it open without keeping the button pressed.
  • Another press ends the exposure and closes the shutter.
