earphones.
CAUTION:
Excessive sound pressure from earphones and headphones can
cause hearing loss. Adjustment of the equalizer to maximum
increases the earphone and headphone outputvoltage 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 your Mobile phone complies with EN
50332-2 Sub clause 7. This specification limits the Mobile phone maximum

15
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 your Mobile phone came with headphones or earphones in the package,
as a set, the combination of the headphones or earphones and the Mobile
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.
This device has been tested to comply with the Sound Pressure Level
requirement laid down in the applicable EN 50332-1 and/or EN 50332-2
standards. Permanent hearing loss may occur if earphones or headphones
are used at high volume for prolonged periods of time.

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 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. Tests for SAR are conducted using
standard operating positions accepted by the FCC with the device
transmitting at its highest certified power level in all tested frequency
bands.
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: YCNS850.
For this device, the highest reported SAR value for usage against the head
is 0.47 W/kg, for usage near the body is 1.19 W/kg.
While there may be differences between the SAR levels of various phones
and at various positions, they all meet the government requirements.
