2. General use
To preserve power, turn OFF the device when not in use.
Once the detector is correctly positioned on its holder, (the fixing system is a ¼ inch screw-
thread - traditional camera tripods or our TAG Heuer HL5), turn the switch clockwise in
order to turn the device ON.
Check that it receives the desired sound signal (like a start pistol or a clap). Adjust the
sensitivity so that the device is not activated by other undesired sounds.

You will find the Battery inside the rear removable cover. The Battery type is a 9V 6LR61.
