Guidelines For Safety And Efficiency
Exposure to radio frequency signals
This portable handset is designed and manufactured
not to exceed the emission limit for exposure to
radio frequency (RF) energy set by the Federal
Communications Commission (FCC) of the U.S.
Government and Canada. These limits are part of
comprehensive guidelines and established permitted
levels of RF energy for the general population. These
guidelines are based on the safety standards previously
set by both U.S. and international standards bodies.
These standards include a substantial safety margin
designed to assure the safety of all persons, regardless
of age and health. The exposure standards for wireless
mobile telephones employs a unit of measure known as
the Specific Absorption Rate, or SAR. The SAR limit set
by the FCC and Canada is 1.6W/kg averaged over one
gram of tissue.
Tests for SAR are conducted using standard operating
positions specified by the FCC with the handset
transmitting at its highest certified power level in all
tested frequency bands. Although the SAR is determined
at the highest certified power level, the actual SAR level
of the handset while operating can be well below the
maximum value. This is because the handset is designed
to operate at multiple power levels.
Before a telephone model is available for sale to the
public, it must be tested and certified to the FCC that it
does not exceed the limit established by government-
adopted requirement for safe exposure. The tests are
performed in positions and locations (for example, at
the ear and worn on the body) as required by the FCC for
each model. The highest SAR value for this handset when
tested for use at the ear is 0.076 W/kg, and when worn
on the body is 0.018 W/kg. (Body worn measurements
differ among handsets depending upon available
accessories and the FCC requirements.) While there
may be differences between the SAR levels of various
handsets and at various positions, they all meet the
government requirement for safe exposure.
For body worn operation, to maintain compliance with
FCC RF exposure guidelines, use only Ascom approved
accessories. When carrying the handset while it is on,
use only the specific Ascom belt clip that has been tested
for compliance.
Use of non-Ascom approved accessories may violate the
FCC RF exposure guidelines and should be avoided.
The FCC has granted an equipment authorization for
this Ascom 9p23 portable handset with all reported
SAR levels evaluated as in compliance with the FCC
RF emissions guidelines. SAR information on this 9p23
portable handset is on file with the FCC and can be found
under the Display Grant section of www.fcc.gov/oet/fccid
after searching on FCC ID O4M9p23.
Most modern electronic equipment (for example,
equipment in hospitals and cars) is shielded from RF
energy. However, RF energy from telephones may affect
some electronic equipment.
Children
Do not allow children to play with your handset. It is not
a toy. Children could hurt themselves or others. Children
could also damage the handset. Product packaging
material is often small and may present a choking
hazard.
Potentially explosive atmospheres
Turn the portable handset off when in an area with a
potentially explosive atmosphere. It is rare, but the
handset or its accessories could generate sparks. Sparks
in such areas could cause an explosion or fire resulting in
bodily injury or death.
Areas with a potentially explosive atmosphere are often,
but not always, clearly marked. They include fueling
areas, (such as gas stations), below deck on boats, fuel
or chemical transfer or storage facilities, and areas
where the air contains chemicals or particles (such as
grain, dust, or metal powders).
Do not transport or store flammable gas, liquid, or
explosives in any compartment of a vehicle which also
contains the handset and accessories.
In the U.S., vehicles powered by liquefied petroleum
gas (such as propane or butane) must comply with
the National Fire Protection Standard (NFPA-58).
For a copy of this standard, contact the National Fire
Protection Association, One Batterymarch Park, Quincy,

Division.
