Absorption Rate (SAR) information:
This device meets the government’s requirements for exposure to radio waves.
The guidelines are based on standards that were developed by independent
scientific organizations through periodic and thorough evaluation of
scientific studies. The standards include a substantial safety margin
designed to assure the safety of all persons regardless of age or health.
FCC Warning
15.19 Labeling requirements.
This device complies with part 15 of the FCC Rules. 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 operation.
15.21 Information to user.
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
15.105 Information to the user.
Note: 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.

FCC RF Exposure Information and Statement
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. This
device was tested for typical body-worn operations with the back of the device
kept 10mm from the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain a appropriate separation
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. Absorption Rate (SAR) information: This device meets the government’s requirements for exposure to radio waves. The guidelines are based on standards
ANSI C63.19:2019 HAC RF Categories
The ANSI Standard presents performance requirements for acceptable
interoperability of hearing with wireless communications devices. When these
parameters are met, a hearing aid operates acceptably in close proximity to a
wireless communications device.

FCC Hearing Aid Compatibility (HAC) Regulations for Wireless Devices
The U.S. Federal Communications Commission (FCC) has established requirements
for digital wireless mobile devices to be compatible with hearing aids and
other assistive hearing devices. When individuals employing some assistive
hearing devices (hearing aids and cochlear implants) use wireless mobile
devices, they may detect a buzzing, humming, or whining noise. Some hearing
devices are more immune than others to this interference noise, and mobile
devices also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless
mobile devices to assist hearing device users find mobile devices that may be
compatible with their hearing devices. Not all mobile devices have been rated.
Mobile devices that are rated have the rating on their box or a label located
on the box.
The ratings are not guarantees. Results will vary depending on the user’s
hearing device and hearing loss. If your hearing device happens to be
vulnerable to interference, you may not be able to use a rated mobile device
successfully. Trying out the mobile device with your hearing device is the
best way to evaluate it for your personal needs. the mobile phone is hearing
aid-compatible.
The worst conversation gain of mobile phone is 12.78 dB.
