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.

For U.S.A. and Canada

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. HA-A18T has been tested and found to comply with FCC/ISED radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the ISED radio frequency (RF) Exposure rules.

Attach the ear pieces firmly when replacing them; failure to do so may result in the ear pieces getting lodged in your ear canal when removed, thus becoming a possible health hazard.

Precautions for use

Do not use the charging cable if the plug area is bent as this may cause fire, burns, or electric shocks. Do not allow the plug or the terminal of the unit to come into contact with liquids (such as sweat, beverages, and antiseptic spray) or foreign objects (such as small pieces of trash, dust, and metallic objects). Stop using immediately if the unit comes into contact with foreign objects or if there are abnormal noises, smells, or smoke emitting from the unit.

Attach the ear pieces firmly when replacing them; failure to do so may result in the ear pieces getting lodged in your ear canal when removed, thus becoming a possible health hazard.
