RITRON, Inc. 505 West Carmel Dr. Carmel, IN 46032-7564 April 25, 2003 Re: AIERIT16-146 To Whom It May Concern: This product is a ten-channel radio transceiver. It is programmed in one of two ways; by pulling frequencies from a table listed in the Users Manual, and by programming via a RITRON PC-based programmer available only to authorized RITRON radio dealers. Allowing the user to pull frequencies from a table that has been pre-loaded into the radio by the manufacturer is a common and FCC approved way of operating this product. Because the frequencies available for use by the end user are loaded into the radio table by the manufacturer or into a specific channel by an approved radio dealer with a restricted access programmer, the product is compliant with 90.203(e). The user has the option of choosing frequencies for either Part 90 or Part 95J (MURS) services from the table, but is instructed not to mix frequencies from these two services in the same radio. This prevents the radio from being capable of operating on frequencies other than the MURS when MURS frequencies are chosen and thus complies with 95.655(d). The MURS frequencies are prominently marked in the frequency table in the Users Manual. In addition, those MURS frequencies which are restricted to an authorized bandwidth of 11.25 kHz are prevented in radio firmware from operating at a higher occupied bandwidth. Sam L. Dulaney Chief Engineer RITRON, Inc.

3 TYPE OF EXHIBIT:RF WARNING STATEMENT FCC PART:1.1310 MANUFACTURER:RITRON, INC. 505 West Carmel Drive Carmel, IN 46032 MODEL:PBS-146D TYPE OF UNIT:VHF-FM Base Transceiver FCC ID:AIERIT16-146 DATE:April 23, 2003 PLEASE NOTE THE FOLLOWING WITH REGARD TO RF EXPOSURE FOR THIS PRODUCT: 1. The User’s Manual contains the following text: EXPOSURE TO RADIO FREQUENCY ENERGY: JBS/PBS-146D: This product generates radio frequency (RF) energy when the PTT button on the front of the unit is depressed. This product has been evaluated for compliance with the maximum permissible exposure limits for RF energy at the maximum power rating of the unit when using antennas available from RITRON. To comply with the General Population/Uncontrolled limits, all persons must be at least 7.9 inches (20 cm) from the AFB-1545 antenna which is supplied by RITRON to be attached directly to the rear of the unit. For the RITRON RAM-1545 magnet mount antenna which can be located away from the unit, all persons must be at least 10.8 inches (28 cm) from the antenna. Antennas other than the two mentioned above have not been tested for compliance and may or may not meet the exposure limits at the distances given. Higher gain antennas are capable of generating higher fields in the strongest part of their field and would, therefore, require a greater separation from the antenna. JBS/PBS-446D: This product generates radio frequency (RF) energy when the PTT button on the front of the unit is depressed. This product has been evaluated for compliance with the maximum permissible exposure limits for RF energy at the maximum power rating of the unit when using antennas available from RITRON. To comply with the Occupational/Controlled limits, all persons must be at least 7.9 inches (20 cm) from the antenna when transmitting. Antennas other than the two mentioned above have not been tested for compliance and may or may not meet the exposure limits at the distances given. Higher gain antennas are capable of generating higher fields in the strongest part of their field and would, therefore, require a greater separation from the antenna. This product is not to be used by the general public in an uncontrolled environment unless compliance with the Uncontrolled/General Population limits for RF exposure can be assured. To limit your exposure to levels at, or below, the levels tested, please observe the following: • Use only the antenna(s) available from RITRON for this model. • Keep talk times as short and infrequent as possible. DO NOT depress the PTT button when not actually wishing to transmit. The radio is equipped with an internal timer to limit continuous transmit times. • When transmitting, maintain a distance of at least 7.9 inches(20 cm). DO NOT hold the radio in such a manner that the antenna is next to, or touching, exposed parts of the body, especially the face or eyes while transmitting. • DO NOT allow children to operate the radio. 4 TYPE OF EXHIBIT:TRANSMITTER EFFECTIVE RADIATED POWER FCC PART: 1.1310 MANUFACTURER:RITRON, INC. 505 West Carmel Drive Carmel, IN 46032 MODEL:PBS-146D TYPE OF UNIT:VHF-FM Base Transceiver FCC ID:AIERIT16-146 DATE:April 23, 2003 PROCEDURE: 1. The measurement for effective radiated power was taken at the RITRON, Inc. 3 meter test site, details of which are on file with the FCC. 2. The PBS-146D was aligned for transmitter operation on 156.100 MHz at the 2.0 Watt maximum obtainable from the unit per the tune-up procedure outlined in the Preliminary Maintenance Manual. The unit was then terminated at the antenna port with the antennas sold with this product. (The user can connect other antennas, however.) 3. All ERP measurements were made with a Hewlett-Packard Model 8560E Spectrum Analyzer, an Electro-Metrics BDA-25 Dipole Antenna, and Electro-Metrics Model LPA-25 Log Periodic antenna. 4. The height of the field strength measurement antenna and orientation of the PBS-146D were varied to provide maximum field strength at the receiving antenna. 5. A substitution antenna, a calibrated ½half-wave dipole, was substituted for the PBS-146D at the PBS- 146D’s location. An RF signal generator was set for the frequency of the PBS-146D with the level at the substitution antenna noted. 6. The height of the substitution antenna was adjusted for maximum signal strength at the field strength measuring antenna. The level at the field strength antenna was noted. 5 TYPE OF EXHIBIT:TRANSMITTER EFFECTIVE RADIATED POWER FCC PART:1.1310 MANUFACTURER:RITRON, INC. 505 West Carmel Drive Carmel, IN 46032 MODEL:PBS-146D TYPE OF UNIT:VHF-FM Base Transceiver FCC ID:AIERIT16-146D DATE:April 23, 2003 EQUATIONS: The substitution antenna is specified from the manufacturer in terms of antenna factor rather than antenna gain. The conversion is: Ga(dbd) = 20 log f (MHz) – AF(dB) – 31.9 The effective radiated power (ERP) is then: ERP(dBm) = Pr(dBm) + Pgen(dBm) – Ps(dBm) – Ga(dBd) Where: Pr is the power level of the radio’s emission at the receiving antenna output. Pgen is the RF signal generator level at the substitution antenna output. Ps is the power level of the substitution antenna emission at the receiving antenna output. Ga is the gain of the substitution antenna. The ERP is converted to watts from dBm by: ERP(watts) = antilog 10 ((ERP(dBm) – 30)/10) 6 TYPE OF EXHIBIT:TRANSMITTER EFFECTIVE RADIATED POWER FCC PART: 1.1310 MANUFACTURER:RITRON, INC. 505 West Carmel Drive Carmel, IN 46032 MODEL:PBS-146D TYPE OF UNIT:VHF-FM Base Transceiver FCC ID:AIERIT16-146D DATE:April 23, 2003 RESULTS: PrPgenPsGaERPERP Antenna (dBm)(dBm)(dBm)(dBd)(dBm)(watts) ___________________________________________________ Nearson AFB-1545+7.00.0-22.0 -0.5+29.50.89 Nearson RAM-1545+11.20.0-22.0-0.5+33.72.34 Certifying Engineer:_______________________________ Kevin G.
