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.
