on Lenovo Phone. Sensitive components inside might become damaged.
Prevent Lenovo Phone and adapter from getting wet
Do not immerse Lenovo Phone in water or leave it in a location where it
can get saturated with water or other liquids.
Do not disassemble or modify Lenovo Phone. Lenovo Phone is a sealed
unit. There are no end-user serviceable parts inside. All internal repairs
must be done by a Lenovo-authorized repair facility or a
Lenovo-authorized technician. Attempting to open or modify Lenovo
Phone will void the warranty.
Lenovo Phone screen is made of glass. The glass might break if Lenovo
Phone is dropped on a hard surface, is the subject of a high impact, or is
crushed by a heavy object. If the glass chips or cracks, do not touch the
broken glass or attempt to remove it from Lenovo Phone. Stop using
Lenovo Phone immediately and contact Lenovo® technical support for
repair, replacement, or disposal information.
Built-in rechargeable battery notice
Do not attempt to replace the internal rechargeable lithium ion battery. Contact
Lenovo Support for factory replacement.
Charge Lenovo Phone in the temperature range of 0°C(32 °F) -
45°C(113°F).You can use any of the following charging methods to safely
recharge the internal battery of Lenovo Phone:
Charging method
Display is on

AC adapter
Approved, but the
battery will charge
A USB connection between
the dc-in connector on
Lenovo Phone and a USB
connector of a personal
computer or other device
that complies with the USB
2.0 standards
This charging method
will compensate the
power consumption.
The battery will
discharge more slowly
than usual.
Approved, but the battery
will charge slowly.
Display is on : Lenovo Phone on

electronic devices, such as Lenovo Phone, while you drive a motor
vehicle or ride a bicycle.
Choking hazard
Keep Lenovo Phone and accessories away from small children. Lenovo
Phone contains small parts that can be a choking hazard to small children.
Additionally, the glass screen can break or crack if dropped on or thrown
against a hard surface.
Plastic bag notice
Plastic bags can be dangerous. Keep plastic bags away from babies and children to
avoid danger of suffocation.
Prevent hearing damage
Lenovo Phone has a headphone connector. Always use the headphone
connector for headphones (also called a headset) or earphones.
Excessive sound pressure from earphones and headphones can cause hearing loss.
Adjustment of the equalizer to maximum increases the earphone and headphone
output voltage and the sound pressure level. Therefore, to protect your hearing,
adjust the equalizer to an appropriate level.
Excessive use of headphones or earphones for a long period of time at
high volume can be dangerous if the output of the headphone or
earphone connectors do not comply with specifications of EN 50332-2.
The headphone output connector of Lenovo Phone complies with EN
50332-2 Sub clause 7. This specification limits Lenovo Phone's maximum
wide band true RMS output voltage to 150 mV. To help protect against
hearing loss, ensure that the headphones or earphones you use also
comply with EN 50332-2 (Clause 7 limits) for a wide band characteristic
voltage of 75 mV. Using headphones that do not comply with EN 50332-2
can be dangerous due to excessive sound pressure levels.
If Lenovo Phone came with headphones or earphones in the package, as
a set, the combination of the headphones or earphones and Lenovo
Phone already complies with the specifications of EN 50332-1. If different
headphones or earphones are used, ensure that they comply with EN
50332-1 (Clause 6.5 Limitation Values). Using headphones that do not
comply with EN 50332-1 can be dangerous due to excessive sound
pressure levels.
Sound Pressure Warning statement
For the device which tests accordance to EN 60950-1:
2006+A11:2009:+A1:2010+A12:2011, it is mandatory to perform audio
tests for EN50332.
This device have been tested to comply with the Sound Pressure Level
requirement laid down in the applicable EN 50332-1and/or EN 50332-2
standards. Permanent hearing loss may occur if earphones or
headphones are used at high volume for prolonged periods of time.
Warning statement:
A pleine puissance, l'écoute prolongée du baladeur peut
endommager l'oreille de l'utilisateur.
Explosive atmospheres
Do not charge or use Lenovo Phone in any area with a potentially
explosive atmosphere, such as at a fueling area, or in areas where the air
contains chemicals or particles (such as grain, dust, or metal powders).
Obey all signs and instructions.
Radio frequency interference
Observe signs and notices that prohibit or restrict the use of mobile
phones (for example, in healthcare facilities or blasting areas). Although
Lenovo Phone is designed, tested, and manufactured to comply with
regulations governing radio frequency emissions, such emissions from
Lenovo Phone can negatively affect the operation of other electronic
equipment, causing them to malfunction. Turn off Lenovo Phone or use
Airplane Mode to turn off Lenovo Phone wireless transmitters when use is
prohibited, such as while traveling in aircraft, or when asked to do so by
Medical devices
Lenovo Phone contains radios that emit electromagnetic fields. These
electromagnetic fields may interfere with pacemakers or other medical
devices. If you wear a pacemaker, maintain at least 6 inches
(approximately 15 cm) of separation between your pacemaker and
Lenovo Phone. If you suspect Lenovo Phone is interfering with your
pacemaker or any other medical device, stop using Lenovo Phone and
consult your physician for information specific to your medical device.
Important handling information

Phone, keep it away from hot or high-voltage environments, such as
electric appliances or electric heating cooking equipment. Only use
Lenovo Phone in the temperature range of -10°C (14 °F) - 45°C
(117 °F) to avoid damage.
When Lenovo Phone is turned on or the battery is charging, some parts
might become hot. The temperature that they reach depends on the
amount of system activity and the level of charge in the battery. Extended
contact with your body, even through clothing, could cause discomfort or
even a skin burn. Avoid keeping your hands, your lap, or any other part of
your body in contact with a hot section of Lenovo Phone for any extended

Specific Absorption Rate information
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
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
OET Bulletin 65 Supplement C. This device has been tested, and meets
the FCC RF exposure guidelines when tested with the device directly
contacted to the body.
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: YCNA850.
For this device, the highest reported SAR value for usage against the
head is 0.38W/kg, for usage near the body is 1.41W/kg.
While there may be differences between the SAR levels of various
phones and at various positions, they all meet the government
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 body-worn 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.
