both release buttons*, then pulling down on the power 

pack. Place your hand underneath the power pack when 

removing to prevent it from falling.

contacts on each power pack.

Push up until the power pack ‘clicks’ firmly into place.

counterclockwise to loosen and reposition each camera 

as shown to the right. Connect one of the white antennas
