98-08901C66-H 2.8 SAFETY PRECAUTIONS 2.8.1 User Operation 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. IMPORTANT: The unit must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons to satisfy FCC RF exposure requirements for mobile transmitting devices. IMPORTANT: To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile transmitters, the following requirements must be met: 2.8.2 Antenna Installation 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 conducted output power and combined cable loss and antenna gain must not exceed 1.5 W ERP (Cellular) and 3.0 W ERP (PCS) to qualify for the rf exposure categorical exclusion requirements of 2.1091. Additionally, the 1900 MHz (PCS) 24.232(b) radiated power limit is 2 Watts EIRP. OEM installers must be provided with antenna installation instruction and transmitter operating conditions for satisfying RF exposure compliance.

98-08901C67-E 1.4.2 User Operation Do not operate your unit when a person is within eight inches (20 centimeters) of the antenna. A person or object within eight inches (20 centimeters) of the antenna could impair call quality and may cause the unit to operate at a higher power level than necessary, as well as expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines. IMPORTANT: The unit must be installed in a manner that provides a minimum separation distance of eight inches (20 centimeters) or more between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting devices. IMPORTANT: To comply with the FCC RF exposure limits and to satisfy the categorical exclusion requirements for mobile transmitters, the requirements described in the following section must be met. 2.8.2 Antenna Installation 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.

May 15, 2003 SAR Test Report for Motorola Mobile Cellular Phone FCC ID IHDT56DB1. Prepared by: Steven Hauswirth, Principal Staff Engineer Motorola Personal Communications Sector Product Safety & Compliance Laboratory Libertyville, Illinois The Motorola Personal Communications Sector Product Safety & Compliance Laboratory has evaluated the mobile cellular phone, FCC ID IHDT56DB1, for the need to conduct SAR evaluation. Due to the design and installation of this product, it is not possible to conduct SAR evaluation. This is because Motorola neither manufactures or supplies the antenna(s) that will be used in the installation of this product. Therefore, this product will be evaluated as a mobile device per 47 CFR §1.1310 titled “Radiofrequency radiation exposure limits”, generally referred to as MPE limits. In 47 CFR § 2.1091, paragraph (b) defines a mobile device as “a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons.” This product is intended to be installed into a vehicle such that the unit is physically secured at one location. In the installation guide supplied with the product, Motorola has made the following statement: “IMPORTANT: To meet the FCC’s RF Exposure Guidelines, the antenna should be installed so there is at least 20 cm of separation between the body of the user and nearby persons and the antenna”. Based on the installation of the transceiver and the antenna, the transmitters radiating structure is more than 20 centimeters from the user. Thus, this product is a “mobile device” as defined in section § 2.1091 paragraph (b). Table 1 (B) of 47 CFR §1.1310 lists the limits for MPE for the General Population. Since the mobile cellular phone operates in the 800MHz cellular band and 1900MHz PCS band, the listed limit of f/1500 applies. The lowest transmit frequency for this product is 824.04 MHz, resulting in a MPE limit of 0.549 mW/cm 2 . Since Motorola neither manufactures or supplies the antenna(s) that will be used in the installation of this product, it is not possible to measure the MPE of the actual device as it is installed per the installation manual. Therefore a calculation of MPE will be described in the next paragraph. The MPE of a radiating structure can be calculated by knowing the transmit EIRP and the distance at which MPE is being calculated. In this case MPE will be calculated at 20 cm, which is the minimum separation between the body of the user and nearby persons and the antenna. The maximum sourced based t…
