1.2 Antenna and Transmission Safety Precautions
The C24 module is normally supplied without an antenna, and is compliant with SAR requirements
provided the following conditions are observed.
Do not operate your unit when a person is within 8 inches (20 centimeters) of the antenna. A person or
object within 8 inches (20 centimeters) of the antenna could impair call quality and may cause the phone
to operate at a higher power level than necessary.
The unit must be installed in a manner that provides a minimum separation distance of 20 cm
or more between the antenna and persons and must not be co-located or operate in conjunction with any
other antenna or transmitter to satisfy FCC RF exposure requirements for mobile transmitting devices.
To comply with the FCC RF exposure limits and satisfy the categorical exclusion
requirements for mobile transmitters, the requirements described in the following section,
, must be met.
The antenna installation must provide a minimum separation distance of 20 cm from users and nearby
persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
The combined cable loss and antenna gain must not exceed +5.3 dBi (800 band). The combined cable
loss and antenna gain must not exceed +4.2 dBi and total system output must not exceed 2.0W EIRP in
the PCS (1900) band in order to comply with the EIRP limit of 24.232 (b). OEM installers must be
provided with antenna installation instruction and transmitter operating conditions for satisfying RF
For system integrations requiring higher antenna gain, or position closer than 20cm from the body, SAR
compliance testing of the completed product will be required. It is strongly recommended that the
system integrator seeks the advice of a suitably accredited test laboratory to develop a test plan and
carry out necessary testing.
CFR 47 Part 15.19 specifies label requirements
The following text may be on the product, user's manual, or container.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired
CFR 47 Part 15.21 Information to user
The user's manual or instruction manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment. In cases where the manual is provided only in a form other
than paper, such as on a computer disk or over the Internet, the information required by this section may
be included in the manual in that alternative form, provided the user can reasonably be expected to have
the capability to access information in that form.
CFR 47 Part 15.105 Information to the user
(b) For a Class B digital device or peripheral, the instructions furnished the user shall include the following
or similar statement, placed in a prominent location in the text of the manual:
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
