This phone 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 exposure standard for wireless mobile
phones 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.* Tests for SAR are conducted
using standard operating positions accepted
by the FCC with the phone transmitting
at its highest certified power level in all
tested frequency bands. Although the SAR
is determined at the highest certified power
level, the actual SAR level of the phone
while operating can be well below the
maximum value. This is because the phone
is designed to operate at multiple power
levels so as to use only the power required
to reach the network. In general, the closer
you are to a wireless base station antenna,
the lower the power output.
The highest SAR value for the model phone
as reported to the FCC when tested for use
at the ear is 0.805 W/kg and when worn on
the body, as described in this user guide,
is 1.420 W/kg. (Body-worn measurements
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.
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user‘s authority to
operate the equipment.
The antenna(s) used for this transmitter must
not be co-located or operating in conjunction
with any other antenna or transmitter.
Health and Safety Information
Radio Frequency (RF) Energy
This model phone meets the government’s
requirements for exposure to radio waves.
* In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg)
averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give additional
protection for the public and to account for any variations in measurements.
Hearing Aid Compatibility with
Mobile Phones
When some mobile phones are used near
some hearing devices (hearing aids and
cochlear implants) users may detect a
buzzing, humming, or whining noise. Some
hearing devices are more immune than
others to this interference noise, and phones
also vary in the amount of interference they
generate in such conditions.
The wireless telephone industry has
developed ratings for some of their mobile
phones, to assist hearing device users in
finding phones that may be compatible with
their hearing devices. Not all phones have
been rated. Phones that are rated have the
rating on their box or a label on the box.
The ratings are not guarantees of
satisfactory results. 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 phone successfully.
Trying out the phone with your hearing
device is the best way to evaluate it for your
personal needs.
M-Ratings: Phones rated M3 or M4 meet
FCC requirements and are likely to generate
less interference to hearing devices than
phones that are not labeled. M4 is the
better/higher of the two ratings.
differ among phone models, depending
upon available enhancements and FCC
requirements.)
While there may be differences between the
SAR levels of individual ZTE R225 phones
and at various positions, they all meet the
government requirement.
The FCC has granted an Equipment
Authorization for this model phone with
all reported SAR levels evaluated as in
compliance with the FCC RF exposure
guidelines. SAR information on this model
phone is on file with the FCC and can be
found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching
on FCC ID: Q78-GR225.
For body-worn operation, this phone has
been tested and meets the FCC RF exposure
guidelines for use with an accessory that
contains no metal and that positions the
handset a minimum of 1.5 cm from the body.
Use of other enhancements may not ensure
compliance with FCC RF exposure guidelines.
If you do not use a body-worn accessory
and are not holding the phone at the ear
level, position the handset a minimum of
1.5 cm from your body when the phone is
switched on.
