shoulder.

SX66 User Manual14
SX66 User Manual 15
Tips on efcient operation
• Extend your antenna fully (if applicable).
• Do not touch the antenna unnecessarily when the phone is in use. Contact with the antenna
affects call quality and may cause the phone to operate at a higher power level than otherwise
needed.
Driving
Laws pertaining to the use of mobile phones while driving vary signicantly from state to state
and sometimes even from locality to locality within states. For example, some areas may allow
persons to use their mobile phones only if they employ a hands-free device, and some areas may
prohibit the use of cell phones entirely. Accordingly, Siemens recommends that persons check
the laws for the areas in which they drive or will be driving. For areas where the use of mobile
phones while driving is permitted, Siemens encourages persons to use their phones responsibly
and to employ hands-free devices. Also, if using your phone while driving, please:
• Give full attention to driving – driving safely is your rst responsibility;
• Use hands-free operation;
• Pull off the road and park before making or answering a call, if driving conditions so require.
For vehicles equipped with air bags
An air bag inates with great force. DO NOT place objects, including either installed or portable
wireless equipment, in the area over the air bag or in the air bag deployment area. If in-vehicle
wireless equipment is improperly installed and the air bag inates, serious injury could result.
Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain
electronic equipment may not be shielded against the RF signals from your wireless phone.
Pacemakers
The Health Industry Manufacturers‘ Association recommends that a minimum separation of
6 inches (21 cm) be maintained between a handheld wireless phone and a pacemaker to avoid
potential interference with the pacemaker. These recommendations are consistent with the inde-
pendent research by and recommendations of Wireless Technology Research.
Persons with pacemakers:
• should ALWAYS keep the phone more than six inches from their pacemaker when the phone is
turned ON;

SX66 User Manual14
SX66 User Manual 15
• should not carry the phone in a breast pocket;
• should use the ear opposite the pacemaker to minimize the potential for interference;
• should turn the phone OFF immediately if there is any reason to suspect that interference is
taking place.
Hearing aids
Some digital wireless phones may interfere with some hearing aids. In the event of such interfer-
ence, you may want to consult your service provider or your hearing aid manufacturer to discuss
alternatives.
Other medical devices
If you use any other personal medical devices, consult the manufacturers of your devices to
determine if they are adequately shielded from external RF energy. Your physician may be able
to assist you in obtaining this information.
Turn your phone OFF in health care facilities when any regulations posted in these areas instruct
you to do so. Hospitals or health care facilities may be using equipment that could be sensitive
to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its representative regarding your vehicle. You should
also consult the manufacturer of any equipment that has been added to your vehicle.
Posted facilities
Turn your phone OFF in any facility where posted notices so require.
Airplanes
FCC and Airline Regulations prohibit using your phone while in the air. Turn your phone OFF
when requested by the airline.
Check and comply with the policy of your airline regarding the use of your phone while the
airplane is on the ground.
Blasting areas
To avoid interfering with blasting operations, turn your phone OFF when in a „blasting area“ or
in areas posted: „Turn off two-way radio.“ Obey all signs and instructions.

SX66 User Manual16
SX66 User Manual 17
Potentially explosive atmospheres
Turn your phone OFF when in any area with a potentially explosive atmosphere and obey all
signs and instructions. Sparks in such areas could cause an explosion or re resulting in bodily
injury or even death.
Areas with a potentially explosive atmosphere are often but not always clearly marked. They
include: fueling areas such as gasoline stations; below deck on boats; fuel or chemical transfer
or storage facilities; vehicles using liqueed petroleum gas (such as propane or butane); areas
where the air contains chemicals or particles, such as grain, dust or metal powders; and any
other area where you would normally be advised to turn off your vehicle engine.
Emergency calls (SOS)
Your wireless phone can be used to make emergency calls. You can make an emergency call
from the main display screen. Enter the local emergency number such as 911 and then press
the Call key. This phone, like any wireless phone, operates using radio signals, wireless and
landline networks, and user-programmed functions. Because of this, connections in all condi-
tions cannot be guaranteed. Therefore, you should never rely solely on any wireless phone for
essential communications (for example, medical emergencies). Remember - to make or receive
any calls, the phone must be switched on and be used in a service area that has adequate signal
strength. Emergency calls might not be possible on all wireless phone networks or when certain
network services or phone features are in use. Check with local service providers regarding
their network features.
Always make certain that your phone is properly charged before attempting any emergency
calls. If you allow your battery to discharge, you will be unable to receive or make calls, includ-
ing emergency calls. You must then wait a few minutes after the charging begins to place any
emergency calls.
When making an emergency call, remember to give all of the necessary information as accurately
as possible. Remember that your wireless phone might be the only means of communication
at the scene of an accident, therefore you should not terminate the call until given permission
to do so.
Batteries and Chargers
Only use original Siemens batteries (100% mercury-free) and charging devices. Use of non-
Siemens batteries and/or charging devices may cause explosion resulting in serious injury
and/or property damage. Use original Siemens accessories in order to avoid possible injury and
property damage and to ensure compliance with applicable laws and regulations. Improper use
invalidates the warranty.

Quality
Battery quality statement
The capacity of your cellular phone battery will be reduced every time it is charged/discharged.
Storage at excessively high or low temperatures will also result in a gradual capacity loss. As
a result, the operating time of your cellular phone may be considerably reduced, even after a
full recharge of the battery.
Regardless of this, the battery has been designed and manufactured so that it can be recharged
and used for six months after the purchase of your cell phone. After six months, if the battery is
clearly suffering from loss of performance, we recommend that you replace it. Please buy only
Siemens original batteries.
Display quality statement
For technological reasons, some small dots in other colors may appear in the display in rare
cases. Please remember that if some dots appear brighter or darker in the display, this generally
does not mean that a fault has occurred.
The U.S. Food and Drug Administration’s (FDA) Center
for Devices and Radiological Health Consumer Update
on Mobile Phones
FDA has been receiving inquiries about the safety of mobile phones, including cel-
lular phones and PCS phones. The following summarizes what is know – and what re-
mains unknown – about whether these products can pose a hazard to health, and what
can be done to minimize any potential risk. This information may be used to respond
to questions.
Why the concern?
Mobile phones emit low levels of radio frequency energy (i.e., radio frequency radiation) in the
microwave range while being used. They also emit very low levels of radio frequency energy (RF),
considered non-signicant, when in the stand-by mode. It is well known that high levels of RF can
produce biological damage through heating effects (this is how your microwave oven is able to
cook food). However, it is not known whether, to what extent, or through what mechanism, lower
levels of RF might cause adverse health effects as well. Although some research has been done

SX66 User Manual20
SX66 User Manual 21
to address these questions, no clear picture of the biological effects of this type of radiation has
emerged to date. Thus, the available science does not allow us to conclude that mobile phones
are absolutely safe, or that they are unsafe. However, the available scientic evidence does not
demonstrate adverse health effects associated with the use of mobile phones.
What kinds of phones are in question?
Questions have been raised about hand-held mobile phones, the kind that have a built-in antenna
that is positioned close to the user’s head during normal telephone conversation. These types
of mobile phones are of concern because of the short distance between the phone’s antenna
– the primary source of the RF – and the person’s head. The exposure to RF from mobile phones
in which the antenna is located at greater distances from the user (on the outside of a car, for
example) is drastically lower than that from hand-held phones, because a person’s RF exposure
decreases rapidly with distance from the source. The safety of so-called “cordless phones”, which
have a base unit connected to the telephone wiring in a house and which operate at far lower
power levels and frequencies, has not been questioned.
How much evidence is there that hand-held mobile
phones might be harmful?
Briey, there is not enough evidence to know for sure, either way; however, research efforts are
on-going. The existing scientic evidence is conicting and many of the studies that have been
done to date have suffered from aws in their research methods. Animal experiments investigating
the effects of RF exposures characteristic of mobile phones have yielded conicting results. A
few animal studies, however, have suggested that low levels of RF could accelerate the develop-
ment of cancer in laboratory animals. In one study, mice genetically altered to be predisposed
to developing one type of cancer developed more than twice as many such cancers when they
were exposed to RF energy compared to controls. There is much uncertainty among scientists
about whether results obtained from animal studies apply to the use of mobile phones. First, it
is uncertain how to apply the results obtained in rats and mice to humans. Second, many of the
studies showed increased tumor development used animals that had already been treated with
cancer-causing chemicals, and other studies exposed the animals to the RF virtually continuously
– up to 22 hours per day.
For the past ve years in the United States, the mobile phone industry has supported research
into the safety of mobile phones. This research has resulted in two ndings in particular that
merit additional study:
1. In a hospital-based, case-control study, researchers looked for an association between mobile
phone use and either glioma (a type of brain cancer) or acoustic neuroma (a benign tumor of
the nerve sheath). No statistically signicant association was found between mobile phone use
and acoustic neuroma. There was also no association between mobile phone use and gliomas
when all types of gliomas were considered together. It should be noted that the average length
of mobile phone exposure in this study was less than three years.
