uses, to be used as personal safety device or medical applications. Refer to IMPORTANT
SAFETY WARNINGS section for more details.
NOTE: This device complies with Part 15 of the FCC Rules and CAN ICES-3(A). Operation is
subject to the following two conditions: (1) this device may not cause harmful interference.
And (2) this device must accept any interference received, including interference that may
cause undesired operations.
INFORMATION TO THE USER
This equipment has been tested to comply with limits for a Class B digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against interference in residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try and correct the interference
by one or more of the following measures:
The COA2 is an ambient CO detector and not intended for in-flue stream
FCC INFORMATION
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that which the
receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
WARNING
:
Any changes or modifications not expressly approved by the manufacturer
could void the user’s authority to operate the equipment.

IMPORTANT SAFETY WARNINGS
WARNING
Read entire Safety Notes section regarding potential hazard and proper instructions before
using this tester. In this manual the word “WARNING” is used to indicate conditions
or actions that may pose physical hazards to the user. The word “CAUTION” is used to
indicate conditions or actions that may damage this instrument.
WARNING
• To ensure safe operation and service of the tester, follow these instructions. Failure to
observe these warnings can result in severe injury or death.
• This meter is designed for trade professionals who are familiar with the hazards of their
trade. Observe all recommended safety procedures that include use of personal protective
equipment.
• Carbon monoxide is life threatening even at relatively low concentrations. Be sure you
understand the risks before investigating potential leaks.
• Do not use the tester if it appears damaged.
• Always adhere to national and local safety codes.
• This COA2 is specified to read Carbon Monoxide from 1-999ppm. The app may continue
to read above this threshold. Professional safety precautions are recommended above
35ppm.
• Threshold safety levels are set to industry standards. By customizing these levels to
higher CO ppm thresholds, users risk personal safety. These settings are saved and used
after exiting and relaunching the App. To reset back to industry standards set the
levels to: Green ≤ 9 ppm; Blue ≤ 34 ppm.
• Any changes or modifications not expressly approved by the manufacturer could void the
user’s authority to operate the equipment.
CAUTION
• The COA2 is designed for ambient testing only. DO NOT place the instrument in flue gas
or warm air streams.
• The COA2 is not designed for in-flue detection. Readings more than 999 ppm will damage
the sensor in the COA2, even if readings continue above the 999ppm range.
• Ensure that the sensor vent at the top of the instrument is free from obstruction.
NOTE: A quick instrument check can be performed by the smoke from a blown out match. Let
smoke enter the
vent
. This will cause the indicated CO level to increase.
