Button Function
Filters
Press and release this button to cycle through the filter options. When
a new filter is selected, the amplifier requires a few seconds to
stabilize. If a user operates the Press-to-listen button during this
period, the current sound level figure will flash to indicate it is
unreliable. When the figure stops flashing, normal operation will
resume.
Turning the Unit On/Off
Turn on the amplifier by pressing any key. However, make sure the sensor
and headphones are connected before turning on the amplifier.
Turn off the unit by pressing the Increase and Decrease buttons
simultaneously. The amplifier will turn off automatically if no button is
pressed for 5 minutes.
Note: Turning off the unit deletes all recorded data.

Minimum Noise Level Display
During operation, the Mikron displays the Minimum Noise Level and the two

whether the user is moving toward or away from the leak.
The main display has three boxes. When the amplifier is turned on, these
boxes are empty. Pressing the Press-to-listen button displays the current
Minimum Noise Level in the right-hand (largest) box. Releasing the Press-to-
Listen button permanently displays the current level in the right-hand box.
