Topaz3 / Maxon subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure far below the Occupational Safety and Health Act (OSHA) and Federal Communications Commission limits. Antennas used for this transmitter must not exceed an antenna gain of 0dBd. The radio must be used in vehicle-moun t config- urations with a maximum operating duty factor not exceeding 50%, in typical push-to-talk configurations. This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use, work related operations only where radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaini ng the min imum separation distance of 47.7 inches (121 cm) between any persons and the antenna. Failure to observe these restrictions will result in exceeding the FCC RF exposure limits. CAUTION - DO NOT transmit for more than 50% of total radio use time …

Correspondence Reference Number: 6888 731 Confirmation Number: TC505136 Date of Original Email: 02/10/2003 Subject: Request for additional information In regards to your recent TCB grant referenced above we kindly request that you provide the following additional information. 1) Updated Rule part in form 731 for 6 KHz emission. Please use rule 90.210 (e) RESPONSE: This radio is not designed or capable of supporting 6.25 kHz operation. 2) Revised antenna gain and MPE analysis. The FCC believes that a safe distance of 1.7 m cannot be maintained for bystander exposure conditions for most vehicles. Please consider lowering maximum antenna gain or power. Revise application accordingly. RESPONSE: The MPE at 45 Watts was recalculated for use with a 0 dBd roof mounted 1/4 wave Vertical Antenna. The result for this configuration yielded a permissible distance of 121 centimeters or 47.7 inches. The Test Report page, which describes the MPE calculation, has been replaced using the 0 dBd antenna gain parameter. (See Page 27 of the revised test rerport). Likewise, the User Manual has been updated to reflect the 0 dBd gain antenna requirement and the updated compliance distance. 3) Updated grant comment to include reference to vehicle roof top only mounting. RESPONSE: The Grant has been modified to agree with the User Manual which states a center of the roof-top mounted antenna. 4) Radiated spurious data using the substitution method. Also, please state RBW for the spectrum used during testing. RESPONSE: The RBW used during testing has been added to the Test Report. 5) Details of how rule section 90.203 e is met. RESPONSE: A letter from Mr. Gerald Happy, LMR Marketing Product Manager, is being submitted with this application stating the software required to reprogram the operating frequencies is only available to authorized two-way radio dealers. I trust the above items have been answered to your satisfaction. I apologize for any lack of data that may have caused confusion. Very truly yours, Frank DeNuzzo T:\T\Topaz3LLC_07K\1175AUT2\oet 6888\FCCresponseLetter.doc

Grant Notes

Power listed is conducted. This device must be restricted to work related operations in an Occupational/Controlled RF exposure Environment, not exceeding a maximum transmitting duty factor of 50%. All qualified end-users of this device must have the knowledge to control their exposure conditions and/or duration, and the exposure conditions and/or duration of their passengers and bystanders, to comply with the General Population/Controlled MPE limit and requirements. A label, as described in this filing, must be displayed on the device to direct users to specific training information for meeting Occupational Exposure Requirements and users must be provided with the training information, antenna installation and transmitter operating conditions for satisfying RF exposure compliance. Antenna installation must be limited to the center of the rooftop of a vehicle. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 1.2m from all persons and must not exceed an antenna gain of 0 dBd.
