Replace the 4 AA Alkaline batteries when the red LED on the control

To silence or mute the audio beep and alarm signal, press the MUTE
button. To restore the audio sound, press the MUTE button again. (Note:
a few seconds is required to restore sound if the mute button is pressed
in rapid succession.)
The Leak Detector will default to the NORM sensitivity level automatically
once the unit comes out of the warm up cycle and the green LED will turn
on.
To change sensitivity levels, press the SENS once for HI sensitivity (red LED
will turn on) and again for LO sensitivity (yellow LED will turn on).
The leak detector comes with a Leak Test Vial that allows the user to
make sure the detector is performing properly. To test:
1. Remove the plastic seal cap on top of the Leak Test Vial by pulling
it off (see fig. below).
2. Turn on the detector and allow the unit to complete the warm up
cycle.
3. Place the sensor close to the small hole in the top of the Leak Test
Vial. The beep rate should increase and the Digital Leak Size
Indicator should display a number from 4-6 indicating that the
sensor and electronics are working properly.
NOTE: Always remember to
replace plastic seal cap after
leak test is completed.
Replace Test Vial when
the green color is
no longer visible.
