Charging the Phone
Your phone’s battery should have enough power for the phone
to turn on, find a signal, and make a few calls. You should fully
charge the battery as soon as possible.
WARNING!
Use only ZTE-approved chargers and USB ables. The use of
unapproved accessories could damage your phone or cause
the battery to explode.
WARNING!
Do not remove the back cover. The battery is not
removable. Removal may cause fire or explosion.
NOTE:
If the battery is extremely low, you may be unable to power on
the phone even when it is being charged. In this case, try
again after charging the phone for at least 20 minutes. Contact
the customer service if you still cannot power on the phone
after prolonged charging.
NOTE:
If the screen freezes or takes too long to respond, try pressing
and holding the Power key for about 10 seconds to restart the
phone.

FCC RF Exposure Information (SAR)
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 United
States.
During SAR testing, this device was set to transmit at its
highest certified power level in all tested frequency bands, and
placed in positions that simulate RF exposure in usage
against the head with no separation, and near the body with
the separation of 10 mm. Although the SAR is determined at
the highest certified power level, the actual SAR level of the
device 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 exposure standard for wireless devices employing a unit
of measurement is known as the Specific Absorption Rate, or
SAR.
The SAR limit set by the FCC is 1.6W/kg. This device is
complied with SAR for general population /uncontrolled
exposure limits in ANSI/IEEE C95.1-1992 and had been
tested in accordance with the measurement methods and
procedures specified in IEEE1528.
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
www.fcc.gov/oet/ea/fccid after searching on FCC ID:
SRQ-ZTU31.
For this device, the highest reported SAR value for usage
9
against the head is 0.392 W/kg, for usage near the body is
0.504 W/kg.
While there may be differences between the SAR levels of
various phones and at various positions, they all meet the
government requirements.
SAR compliance for body-worn operation is based on a
separation distance of 10 mm between the unit and the human
body. Carry this device at least 10 mm away from your body to
ensure RF exposure level compliant or lower to the reported
level. To support bodyworn operation, choose the belt clips or
holsters, which do not contain metallic components, to
maintain a separation of 10 mm between this device and your
body.
RF exposure compliance with any body-worn accessory,
which contains metal, was not tested and certified, and use
such body-worn accessory should be avoided.
FCC Regulations
This mobile phone 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.
This mobile phone 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
10
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.
CAUTION: 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.
Specific Absorption Rate (SAR)
Your mobile device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to radio waves
recommended by international guidelines. These guidelines
were developed by the independent scientific organization
ICNIRP and include safety margins designed to assure the
protection of all persons, regardless of age and health.
The guidelines use a unit of measurement known as Specific
Absorption Rate, or SAR. The SAR limit for mobile devices is
2 W/kg and the highest SAR value for this device when tested
at the head was 0.348 W/kg*, and when tested at the body
was 1.220 W/kg*. As mobile devices offer a range of functions,
they can be used in other positions, such as on the body as
described in this user guide**.
As SAR is measured utilizing the device’s highest transmitting
11
power, the actual SAR of this device while operating is
typically below that indicated above. This is due to automatic
changes to the power level of the device to ensure it only uses
the minimum power required to communicate with the
network.
* The tests are carried out in accordance with EN 50360, EN
50566, EN 62479, EN 62209-1 and EN 62209-2.
** Please see body worn operation
Body Worn Operation
Important safety information regarding radio frequency
radiation (RF) exposure:
To ensure compliance with RF exposure guidelines the phone
must be used with a minimum of 5 mm separation from the
body.
Failure to observe these instructions could result in your RF
exposure exceeding the relevant guideline limits.
Limiting Exposure to Radio Frequency (RF) Fields
For individuals concerned about limiting their exposure to RF
fields, the World Health Organization (WHO) provides the
following advice:
Precautionary measures: Present scientific information does
not indicate the need for any special precautions for the use of
mobile phones. If individuals are concerned, they might
choose to limit their own or their children’s RF exposure by
limiting the length of calls, or using ‘hands-free’ devices to
keep mobile phones away from the head and body.
Further information on this subject can be obtained from the
WHO home page http://www.who.int/peh-emf (WHO Fact
sheet 193: June 2000).
Regulatory Information
The following approvals and notices apply in specific regions
as noted.
