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.
