INSTRUCTIONS
1. Move the STARTEK-C to a fresh-air environment. Press the button
to turn the unit on.
2. The LED will flash rapidly for a period of time (see WARM-UP TIME,
below) to indicate warm-up and auto-calibration, afterwards the unit
will begin beeping and flashing green.
3. Unit turns on in the high sensitivity level, which is preferred for most
small leaks. To operate the unit in the low sensitivity level, press the
button twice (double-click like a computer mouse). The LED will
fade from green to red and a sweeping sound effect of high to low
pitch will be heard. This low sensitivity mode is useful for
pinpointing very large gas leaks.
4. Double click again to change back to high sensitivity.
5. Move the probe towards a suspected gas leak at a rate of less than
1 inches (25 mm) per second, no more than ¼ inch (5 mm) away
from the suspected source.
6. If a leak exists, the sound will increase in rate and pitch and the
LED will start flashing rapidly.
7. Alarms caused by very large leaks may take a long time to clear. If
this is the case, switch to the low sensitivity mode as detailed in (3)
above.
8. To turn the STARTEK-C off, press and hold the button for 3
seconds.
9. To conserve battery life, the STARTEK-C will turn itself off after 8-10
minutes of inactivity.
WARM-UP TIME
The warm-up time for the STARTEK-C will range between 25 seconds
and 1.5 minutes. Each sensor has different warm-up characteristics
that change with use over the life of the sensor. The STARTEK-C has
built-in intelligence that recognizes sensor differences and adjusts the
warm-up time automatically for maximum sensitivity and stability.

MISSING/DAMAGED SENSOR ALARM
If the sensor is damaged, a sweeping alarm and a red-green flash will
indicate the problem.
BATTERY INDICATOR/LOW BATTERY
SHUTDOWN
A flashing LED during normal operation also reflects the battery level:
• Green: Batteries are fresh.
•
Orange: Batteries are low and should be changed.
If the batteries are nearly empty, the LED will turn solid red and a
two-tone alarm will be noted for 5 seconds, before STARTEK-C will
power itself off.
RECALIBRATION
When the STARTEK-C is turned on, the unit automatically calibrates the
sensor for maximum sensitivity. Occasionally, the signal from the
sensor may drift (especially if moving from one location to another where
the ambient humidity changes), causing a continuous alarm that will not
clear. In this case, simply power the unit off and on again, or use the
following recalibration procedure:
To recalibrate the unit:
1. Move the unit away from any suspected leaks and into fresh air.
2. Quickly press the button four (4) times. This must be done within
one second.
3. The LED will flash rapidly for about 10 seconds, indicating
recalibration.
4. The unit will return to normal operation in the high sensitivity mode.
