INSTRUCTIONS
1. Press the button to turn the unit on.
2. The LED will flash orange for a short moment to indicate auto-reset,
afterwards the unit will begin beeping and flashing green.
3. To reset the unit to the existing level of ambient refrigerant, press
and release the button. The LED will flash orange briefly to indicate
the reset. All levels of refrigerant less than the reset level will be
ignored.
4. Unit turns on in the low sensitivity level, which is adequate for most
leaks. Press the button twice (double-click like a computer mouse).
The LED will fade from red to green and a sweeping sound effect of
low to high pitch will be heard. The sensitivity is now set for 3g/year
(0.1oz/yr). This mode should only be used for looking for leaks of
less than 14g/year (0.5 oz/yr).
5. Double click again to change back to low sensitivity.
6. Move the probe towards a suspected refrigerant leak at a rate of
less than 2 inches (50 mm) per second, no more than ¼ inch (5 mm)
away from the suspected source.
7. If a leak exists, the sound will increase in rate and pitch and the
LED will start flashing rapidly.
8. To turn the STARTEK off, press and hold the button for 3 seconds.

about 5 minutes to conserve batteries.
