What the thread found

• The camera run button on Preston HU3 hand units can produce an audible click without actually engaging the camera, requiring forceful rather than light pressure to activate
• The run indicator light only illuminates when the camera actually starts rolling, not during failed button activation attempts
• Similar issues can occur with the middle menu button on the HU3
• Manufacturing contamination of tactile switches during circuit board cleaning is the likely cause of button responsiveness problems
• Preston offers retrofitting service to replace problematic switches

Depends on

• This was reported for HU3 units with software versions v1.11 and v1.12
• The issue appears intermittent and may be user-dependent in terms of how buttons are pressed
• No information provided about whether this affects all manufactured units or only some batches
