INFORMATION TO THE USER

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a 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 to correct the interference by one or more of the following measures:

• 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 to which the
receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

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 COA1 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 COppm thresholds, users risk personal safety. These setting are saved and used
after exiting and relaunching the App. To reset back to industry standards set the
levels to: Green ≤ 10 Orange ≤ 35 Red.

CAUTION

• The COA1 is designed for ambient testing only. DO NOT place the instrument in flue gas
or warm air streams.

• The COA1 is not designed for in-flue detection. Readings more than 999 ppm will damage
the sensor in the COA1, even if readings continue above the 999ppm range.

• Ensure that the sensor vent at the top of the instrument is free from obstruction.

• When zeroing the COA1, the adapter should be in fresh air. The COA1 uses an
electrochemical sensor, which are subject to long-term drift pending use and CO levels
during use. Calibration services are available at UEi Recertification Centers. Call or visit
us online for more information.

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.
