shut down the mobile phone
immediately.
Hearing aid: Certain digital
wireless mobile phones may
affect the hearing aid. If the
interference exists, contact the
manufacturer of the hearing
aid.
The medical appliances: To use
the other personal medial
appliances, consult the
manufacturer first to check
whether these appliances
shield radio electric waves. You
can also get the information
from the doctor. If there is the
sign of forbidding using mobile
phones around the

rehabilitation facility, shut down
the mobile phone.
Car facilities: Radio signals
may affect electronic devices
on the car. Confirm the related
information with the device
manufacturer.
Emergency Calls
Same as other wireless mobile
phones, phone use radio signals,
but cannot guarantee that radio
signals are connected under all
circumstances. Thus, do not solely
depend on the mobile phone for
important calls, such as under
urgent medical situations.
To ensure that you can make calls
and receive calls, place the mobile
phone in a network service area
with powerful signals, and ensure
that it is powered on.
To dial emergency calls, enter the
local emergency number and press
![](/img.php?id=2876947&img=bg36.png)
Jethro SC118 User Manual

the dial key to initiate the call.
Other Important Safety
Information
Only use auxiliary parts of the
manufacturer or authorized by
the manufacturer. Failure to
comply may affect the
performance of the mobile
phone, damage the phone set,
result in personal injuries, or
violate national specifications
for mobile terminal products.
Use the slightly wet cloth or
antistatic cloth to clean the
phone set. Do not use dry cloth
that may generate static
discharge. Do not use chemical
cleaning agents to clean the
mobile phone surface. Shut
down the mobile phone while
you clean it.
The mobile phone may
generate electrical magnetic

field. Do not place it close to
magnetic storage media such
as computer disks. It may
cause interferences if you use
the mobile phone around
electronic appliances such as
televisions, phones, radios, and
person computers, so the
performance of the mobile
phone is affected accordingly.
Do not expose the mobile
phone under direct sunlight.
Failure to comply may cause
the mobile phone to be
overheated.
Prevent various fluids from
entering the mobile phone.
Failure to comply may damage
the mobile phone.
Do not throw or beat the mobile
phone. Failure to comply may
damage internal circuit boards
on the mobile phone.
Do not connect the mobile

Note:
1. The company is
committed to gradually
reduce poisonous and
harmful substances until
they are completely
replaced.
2. Due to the function

some models do not
have the earphone,

To achieve better
performance, the bolt

exempted in RoHS
instructions, because
they are technical

This mobile device is a radio
transmitter and received. It is
designed not to exceed the limits of
radio electric wave radiation
suggested by ICNIRP. These
specifications are made by the
independent scientific organization
ICNIRP, which include a series of
safety coefficients to ensure the
security of group members at all
ages and under any health
situations.
The specific absorption rate (SAR)
is the unit that measures the
radiation of mobile devices.
According to the ICNIRP
specifications, the average SAR is
2.0 W/kg per 10g body weight. The
SAR is measured at the standard
body position. It is verified that this
device has the highest transmission
power on all measured bands.
Because this device is designed to
only use the power level necessary
![](/img.php?id=2876947&img=bg3c.png)
Jethro SC118 User Manual
60
for network connection, so the
actual SAR may be lower than the
maximum value during the
operation. The actual SAR changes
with many factors, such as the
distance with the base stations.
According to the ICNIRP
specifications, the maximum
SAR is 0.5 8 W/kg when this
device is used near the ear.
If the auxiliary part is used, the SAR
may be different. The SAR is also
different according to report
requirements, test requirements,
and network bands in different
nations or areas.

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.

This GSM phone meets the
government's requirements for
exposure to radio waves. The
guidelines are based on standards that
were developed by independent
scientific organizations through
periodic and thorough evaluation of
scientific studies. The standards
include a substantial safety margin
designed to assure the safety of all
persons regardless of age or health.
FCC RF Exposure Information and
Statement The SAR limit of USA
(FCC) is 1.6 W/kg averaged over one
gram of tissue. Device types: SC118
(FCC ID: 2AAWJSC118) has also
been tested against this SAR limit. The
highest SAR value reported under this
standard during product certification
for use at the ear is 0.86W/kg.
