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.
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 circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help and for additional
suggestions.
Warning
The user is cautioned that changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.

FCC RF Exposure Information
Your handset is a radio transmitter and receiver. It is designed and manufactured not
to exceed the emission limits for exposure to radio frequency (RF) energy set by the
Federal Communications Commission of the U.S. Government.
The guidelines are based on standards that were developed by independent scientific
organization 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 and health.
The exposure standard for wireless handsets employs a unit of measurement known
as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6 W/kg. The tests are performed in positions and
locations (e.g. at the ear and worn on the body) as required by the FCC for each
model.
The highest SAR value for this model handset as reported to the FCC when tested for
use at the ear is 0.985 W/kg, and when worn on the body in a holder or carry case, is
1.034 W/kg.
Body-worn Operation; This device was tested for typical body-worn operations with
the handset kept 1 cm from the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain a 1 cm separation distance between the
user’s body and the handset. The use of beltclips, holsters and similar accessories
should not contain metallic components in its assembly.
The use of accessories that do not satisfy these requirements may not comply with
FCC RF exposure requirements, and should be avoided. The FCC has granted an
Equipment Authorization for this model handset with all reported SAR levels
evaluated as in compliance with the FCC RF emission guidelines. SAR information on
this model handset is on file with the FCC and can be found under the Display Grant
section of (http://www.fcc.gov/oet/ea/) after searching on FCC ID JOYYKDA25.
Additional information on Specific Absorption Rates (SAR) can be found on the FCC
website at (https://www.fcc.gov/general/radio-frequency-safety-0).
The World Health Organization has stated that present scientific information does
not indicate the need for any special precautions for the use of mobile devices. They
note that if you want to reduce your exposure then you can do so by limiting the
length of calls or using a hands-free device to keep the mobile phone away from the
head and body.
