Inserting the SIM card
1. Insert the end of the eject tool into the hole of the card
tray and press firmly until the tray pops out.
2. Put one or two nano-SIM cards into the tray.
3. Push the card tray back into the phone.
Note
Dimensions of a nano-SIM card: 9m*12mm.
Charging the battery
Connect the phone to the power outlet using the included USB
cable and power adapter.
Note
Your phone and power adapter might heat up while
charging.
Use other USB cable or power adapter might decrease
2
the life span of your phone or cause fire, explosion and
other hazards.
Disposal of your old phone
When the wheelie bin symbol is attached to a product,
it means the product is covered by the European
Directive 2012/19/EU.
All electrical and electronic products should be
disposed of separately from normal household waste via
designated collection points provided by government or local
authorities.
The correct disposal of electrical and electronic products will
help protect the environment and human health.

Declaration of RoHS Compliance
We’re determined to reduce the impact we have on the environment
and take responsibility for the earth we live on. So this document
allows us to formally declare that the AC57DIOM, manufactured by
Nubia Technology Co., Ltd, fully complies with the European
Parliament’s RoHS (Restriction of Hazardous Substances) Directive
2011/65/EU, with respect to all the following substances:
(1) Lead (Pb)
(2) Mercury (Hg)
(3) Cadmium (Cd)
(4) Hexavalent Chromium (Cr (VI))
(5) Polybrominated biphenyl (PBB)
(6) Polybrominated diphenyl ether (PBDE)
Our compliance is witnessed by written declaration from our
suppliers. This confirms that any potential trace contamination
levels of the substances listed above are below the maximum level
set by EU 2011/65/EU, or are exempt due to their application.
The AC57DIOM manufactured by Nubia Technology Co., Ltd meets
all the requirements of EU 2011/65/EU.
Health and safety
The device meets international guidelines for exposure to radio
waves.
Your device is a radio transmitter and receiver. It’s designed not to
exceed the limits for exposure to radio waves recommended by
international guidelines. The guidelines were developed by the
International Commission on Non-lonizing Radiation Protection
(ICNIRP), an independent technical standards body, and include
margins designed to assure the safety of all persons, regardless of
age and health. These guidelines use a unit of measurement known
as Specific Absorption Rate (SAR). The SAR limit for mobile
devices is 2.0 W/kg and the highest SAR value for this device when
tested for use at the head was 1.41 W/kg and when tested for use at
the body was 0.929 W/kg
1. The tests are carried out in accordance with IEC standard IEC
62209-2.

In SAR measurement, the separation distance between the phone
and test device is 5mm.
As SAR is measured when the device is on its highest transmitting
power, the actual SAR of this device while operating normally is
typically below the levels shown above. This is because the device
automatically changes its power level to ensure it only uses the
minimum level required to reach the network.
The World Health Organization has stated that present scientific
information does not indicate the need for any special precautions
for the use of mobile devices.
Important safety information
For your own health and safety, please follow the
radio frequency (RF) radiation exposure guidelines and keep your
phone no less than 1.5 cm away from your body.
Failure to do this could mean that your RF exposure exceeds the
guideline limits.
How to limit your radio frequency (RF) exposure
The World Health Organization (WHO) gives the following advice to
people who want to limit their exposure to RF radiation…
Present scientific information does not indicate the need for any
special precautions for the use of mobile phones. If individuals are
concerned, they may 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 the subject can be obtained from the World
Health Organization website at http://www.who.int/peh-emf WHO
Fact sheet 193: June 2000.
Safety warning
To prevent possible hearing damage when using a
headset, do not use high volume for long period.
Use the earphone carefully. Excessive sound
pressure from headsets and headphones can cause hearing
loss.
Adapter shall be installed near the equipment and shall be
easily accessible.
The phone's normal operating temperature is -10℃ ~ 45℃. In
order to ensure the normal phone functions, do not use this
phone outside the temperature range.
