POWER button

Initial powering takes 60 seconds. Once on, the system is set to stand-by with a single quick press on the power button. The battery lifetime in this standby mode is more than 120 hours. Another quick press on the power button returns to ON mode. To preserve battery power in the "ON Status", auto stand-by is initiated if no buttons are pressed for 3 minutes.

 RECORD button

On the HM-324, this button will freeze the image for up to 2 minutes. The camera will return to live imaging upon any press of the button.
Depending on the HM-Series camera model, a single fast push of the RECORD button records a single frame of data to the SD card. During this operation the image is frozen for approximately 1 second. If the operator presses and holds the RECORD button for more than 2 seconds, video recording is started and continued until the operator releases the button. During video recording a "record" icon is visible in the viewfinder.
