other electronic devices.
Interference with medical equipment
Follow rules and regulations set forth by hospitals and
health care facilities. Do not use your device where
prohibited.
Some wireless devices may affect the performance of
hearing aids or pacemakers. Consult your service provider
for more informat ion.
Pacemaker manufacturers recommend that a minimum
distance of 15 cm be maintained between a device and a
pacemaker to prevent potent ial interference with the
pacemaker. If using a pacemaker, hold the device on the side
opposite the pacemaker and do not carry the device in your
front pocket.
Protecting your hearing when using a headset
To prevent possible hearing damage, do not
listen at high volume levels for long periods.
Using a headset at high volumes may damage your hearing.
To reduce this risk, lower the headset volume to a safe and
comfortable level.
Exposure to high volumes while driving may cause
distraction and increase your risk of an accident.
15
Areas with flammables and explosives
Do not use the device where flammables or explosives are
stored (in a gas station, oil depot, or chemical plant, for
example). Using your device in these environments increases
the risk of explosion or fire. In addition, follow the
instructions indicated in text or symbols.

EU regulatory conformance
Body worn operation
The device complies with RF specifications when used near
your ear or at a distance of 1.5 cm from your body. Ensure that
the device accessories, such as a device case and device holster,
are not composed of metal components. Keep the device away
from your body to meet the distance requirement.
Certification information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As
recommended by international guidelines, the device is
designed not to exceed the limits for exposure to radio waves.
These guidelines were developed by the Internat ional
Commission on Non-Ionizing Radiat ion Protection (ICNIRP), an
independent scientific organization, and include safety
measures designed to ensure the safety of all users, regardless
of age and health.
The Specific Absorpt ion Rate (SAR) is the unit of measurement
for the amount of radio frequency energy absorbed by the body
when using a device. The SAR value is determined at the highest
certified power level in laboratory conditions, but the actual
SAR level during operat ion can be well below the value. This is
because the device is designed to use the minimum power
required to reach the network.
The SAR limit adopted by Europe is 2.0 W/kg averaged over 10
grams of tissue, and the highest SAR value for this device
complies with this limit.
The highest SAR value reported for this device type when tested
at the ear is 0.27 W/kg, and when properly worn on the body is
0.22 W/kg.
Statement
Hereby, Huawei Technologies Co., Ltd. declares that this device
is in compliance with the essential requirements and other
relevant provisions of Directive 1999/5/EC.
21
For the declaration of conformity, visit the web site
http://consumer.huawei.com/certification.
The following marking is included in the product:
This device may be operated in all member states of the EU.
Observe national and local regulations where the device is
used.
This device may be restricted for use, depending on the local
network.
