All personnel must remain at least 7” from an unobstructed antenna to avoid extended peri- ods of RF exposure. With trucks logging more than 50 billion vehicle miles on the nation's roads, more maintenance and more work zones increases the opportunity for more accidents. Higher speeds, inattentive driving and closer spacing contribute to rear-end vehicle collisions and hazardous conditions for road construction workers. The Wizard® is designed to provide advanced warning of impending traffic slowdowns to give all vehicles, especially heavy trucks, the necessary time to stop. The Wizard is a completely portable wireless broadcasting system adaptable to any work site, sending localized messages on selected CB channels. The Wizard counts down the selected interval for sending, listens for a break in activity on channels 9 and 19 (or other user selected and emergency CB chan- nels), and broadcasts when clear. Care is taken to not interfere with normal CB communication between vehicles. A short message alerts the driver to slow down. The message can be broad- cast on a second user selected channel if desired. Messages can be changed at the site, broadcast distances adjusted for traffic backup, and message frequency modified to compensate for average speeds. WARNING The Citizens Band (CB) Radio Service is under the jurisdiction of the Federal Communications Commission (FCC). Any adjustments or alterations which alter the performance of the transceiver's original FCC type acceptance, or change the frequency determining method, are strictly prohibited. Replacement or substitution of crystals, transistors, ICs, regulator diodes, or any other part of a unique nature, with parts other than those recommended by Highway Technologies, Inc., may cause violation of the technical regulations of Part 95 of the FCC rules or violation of type acceptance require- ments of Part 2 of the rules. This radio has been type accepted and certified by the FCC.

This could be for a snow plow, paint truck or crash truck. It is within 2 feet of the driver, who monitors the channel traffic to make sure the message is getting out. The antenna is placed on the roof of the vehicle with a magnetic mount. It can also be used in the front seat of a trooper car under similar circumstances. Our contemplation of remote operation was in response to PennDOT requests to be able to place a permanent roadside Wizard which could be activated by telephone for quicker response, especially during foul weather. The presumption was that having the Wizard listen electronically for busy conditions was equivalent to being under direct control. That model does not yet exist. If and when we wish to seek approval for such a device, we will request a suitable ruling. However, that issue does not apply to the current model. David C. Johnson Vice President Highway Technologies, Inc.

WIZARD® Work Zone Alert and Information Radio GENERAL DESCRIPTION The WIZARD is a safety device which broadcasts prerecorded traffic alert and warning voice messages to the motoring public to prevent accidents and improve traffic flow. It employs the Citizens Band radio to air these messages. The messages are transmitted at regular fixed intervals of 30, 60, or 90 seconds as determined by the operator of the WIZARD. Three messages - each with a length of up to 18 seconds - may be recorded for transmission. A typical message takes 12 seconds. The WIZARD can broadcast any one of the prerecorded messages on 2 selected CB radio channels in a sequential manner. As an example, MESSAGE # 2 might be selected for broadcast. It will be transmitted on channel A (the first CB channel assigned). Immediately thereafter, the same message could be broadcast on channel B if a second CB channel was assigned and active. With a standard configuration, the operator can choose channel 3, 9, 17,19, 21, or 36. Channel 19 is the favorite channel because it is the choice of truckers. However, on request to the factory, any of the 40 normal CB channels may be designated as one of the 6 available. SEQUENCE OF OPERATION 1. The operator selects the time interval between messages, and assigns one of the 6 available channels as Channel A. If desired, another channel may be assigned as channel B. Using the microphone, an alert message can be recorded. If a suitable message has previously been recorded, it can be selected instead. The message can be previewed by pressing the PUSH TO LISTEN switch. It can be re-recorded if needed to improve clarity and completeness. Once set up, the mode is switched to TRANSMIT, and the rest is automatic. 2. The WIZARD begins by examining channel A for activity. If the activity on this channel is below the factory set threshold, the channel is considered clear and the message is broadcast. If the channel is found to be "busy", activity is continuously monitored until it is found to be clear. The message is broadcast immediately after the channel is found to be clear. Once the message has been transmitted, the interval timer starts the countdown to the next channel A transmission. While it is counting down, the Wizard checks to see if channel B has been enabled. If so, activity is monitored on that channel until it is clear. Then the message is broadcast. 3. In a typical configuration, the channel chosen to be channel B is likely to be a relatively quiet channel that will usually be clear at first try. However, If channel B should be “busy” for very long, it will not be allowed to interfere with the next scheduled channel A transmission. Thus, if channel B is busy for more than 20 seconds, no message will be broadcast on this channel for this cycle. After the next channel A transmission, the system will test channel B again and transmit promptly when the channel is determined to be clear. IMPORTANT NOTE A UNIDEN (brand) Citizens Band transceiver model PRO 510 XL as produced by the manufacturer is used as the transmitter for the WIZARD. The F.C.C. I.D. number for this transceiver is AMW3K2-317. Please refer to the appropriate documents for this make and model of transceiver for details on the operation of this device. This unit is very similar to the previously approved unit (NB3103) except that a different Uniden model CB is used and the control circuitry is driven by a microprocessor rather than discrete components.

MPE Calculations FCC § 1.1307, Radio Frequency Exposure The EUT described in this report has been evaluated to the MPE limits for General Population/Uncontrolled Environment. As the manufacturer does not specify or sale any antenna with the radio the MPE calculations are based on commercially available CB antennas. According to Section 1.1310 of the FCC rules, the uncontrolled RF exposure limit for this frequency range is 180/f 2 (mW/cm 2 ). To comply with the exposure limits for this section, humans must not be too close to the transmit antenna. The following formula was used to calculate the minimum safe distance from the antenna that must be maintained during use (no time averaging was used): S = (PG)/(4πR 2 ) Where, S = Power Density P = Output Power at the Antenna Terminals in mW G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna in cm For this device, the calculation is as follows: (Based on worst case power and frequency) S = FCC Limit = 180/(26.9848) 2 mW/ cm 2 = 0.25 mW/ cm 2 P = Output Power = 3550 mW G* = Antenna Gain = 2.15 dBi = INVLOG(2.15/10) = 1.64 *Antenna Gain based on an ideal ½-wave dipole. Therefore: R = 43cm (Continuous operation) From this calculation, the minimum safe distance is 43 cm for continuous operation. Based on the worst- case usage of the device the source-based time averaging would be a 40% duty cycle. This would reduce the minimum safe distance to be 17.2 cm. R = 17.2 cm (Source-based time-averaging) The antenna for this radio is either located on top of a construction trailer roof or on top of a road construction vehicle and will be located greater than 17.2cm from personnel. For this reason the minimum safe distance is met by the typical mounting of the antenna. )()(25.0464.13550××÷×=πmWR
