Systems using the c18 are subject to mandatory EMC testing under directive 89/336/EEC. Other directives, such as the
LVD directive 73/23/EE, may also apply to a system using the c18 module.

SAFETY PRECAUTIONS
c18 modules are not ESD protected. ESD preventive measures must be taken when handling the modules.
!
Integrators should design ESD protection on all external interfaces.
Caution
When using the headset earpiece, verify the audio level as a safety precaution and limit the maximum voltage by
!
the serial resistor. See "Headset Interface" on page 30.
Warning
2.6.1
User Operation
Do not operate your telephone 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. In addition, it may expose that person to RF energy in excess of that established by the FCC RF Exposure
Guidelines.
The telephone must be installed in a manner that provides a minimum separation distance of 20 cm or more
!
between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting
devices.
Warning
To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile
transmitters, the requirements described in this manual must be met.
2.6.2
Antenna Installation
Output power listed is conducted at antenna terminals. This OEM module transmitter operates with external vehicle-mounted
antennas. OEM installers must follow the antenna installation instructions of the antenna manufacturer, and must meet
transmitter operating conditions for satisfying RF exposure compliance. In addition, the following conditions 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 operated in conjunction with any other antenna or transmitter.
• The combined cable loss and antenna gain must not exceed +6.1 dBi. The total system output must not exceed 1.5 Watts ERP
(Cellular)/3.0 Watts EIRP (PCS) to qualify for the categorical exclusion requirements of 2.1091.
