POWER ON: Turn on or off by long press-
ing the ON/OFF button. The power LED
will illuminate green unless battery is low.
WARM-UP: During warm-up, the unit
will beep slowly and the signal LEDs will
continuously scroll from left to right until
warm-up is complete. Warm-up time is
45 to 90 seconds.
SEARCH: Detector is ready for use when
signal LEDs stop scrolling from left to
right and a different beep rate can be
heard.
If a leak is detected, the signal LEDs will
illuminate from left to right and the beep
rate will increase. The number of LEDs
illuminated indicates the strength of the
leak.
The default mode is Standard mode. In
Standard mode, the detector automati-
cally zeros to the background refrigerant.
Once it zeros, the alarm will stop and it
will only alarm to a higher concentration
of refrigerant. To reset the zero point,
hold the probe in clean air for a few
seconds to allow the detector to re-zero.
ADJUSTING THE SENSITIVITY LEVELS:
Short press the ON/OFF button to toggle
sensitivity from high to low. The HIGH or
LOW LED will illuminate to indicate the
current sensitivity setting. High is the
default setting during power on.
MANUAL MODE: Short pressing the
MODE button toggles between Standard
mode and Manual mode. Manual mode
is indicated by the 1st signal LED slow
blinking and both HIGH and LOW LEDs
being off.
In manual mode, if a leak is detected, the
detector will alarm until the MODE button
is long pressed. The HIGH and LOW LEDs
will blink for 1 second to indicate the

detector is zeroing. At this point, the
detector will only alarm if a high concen-
tration of refrigerant is detected.
You can also reset the zero point in clean
air by holding the detector in clean air and
long pressing the MODE button again.
BATTERY AND CHARGING: The power
LED will slow blink red when the battery
is 10% or less. If the battery is depleted
completely, the power LED will illuminate
solid red and the unit will not operate.
To charge the unit, plug the supplied
micro USB cable into an appropriate USB
charging port per the input specifications
(see specifications).
When charging, the power LED will slow
blink green until fully charged, then
remain solid green.
ERRORS: If the battery is above or below
charge temperature, the unit will not
charge and the power LED will alter-
nate red and green. In this case, let the
battery cool or warm up. The unit will
charge once the battery is within the safe
operating temperature.
Other faults or internal errors are indicat-
ed when all LEDs blink. Contact Ritchie
Engineering Company, Inc. for service in
this case.
