IZARD W THE Wizard Messages - Suggested Guidlines Wizard will accept any message. Each message can be up to 15 sec- onds long. However, to maximize effectiveness, please follow the following guidelines as much as possible. Bear in mind that the Wizard is an FCC-approved device, intended for specific traffic advice, not generic messages (such as “Drive safely”). The antenna for this device must be mounted on top of the roof of the vehicle or on top of the construction site trailer away from near- by personnel. All personnel must remain at least 8“ from an unob- structed antenna to avoid extended periods of RF exposure. 1. Minimize background noise Recording in a quiet area (in a vehi- cle or off site) is best. When recording on site, try to choose a break in the traffic noise and hold the mic close to the mouth. 2. Keep the message short Most messages can be delivered in less than 10 seconds. Include only enough information to get the mes- sage across. 3. Keep the message relevant A pattern of broadcasting outdated or not at the moment applicable messages will eventually cause them to be ignored. 4. Include key information If the message only concerns north- bound traffic or a particular exit or location, say so. 5. Use a higher pitch Female voices are more likely to get every- one’s attention. Extremely low male voices do not transmit as well. 6. Speak clearly Be sure to enunciate and speak slowly enough to avoid run-together words 7. Be Pleasant In many situations, the message may be heard sever- al times. An unpleasant message will be annoying. 8. Identify the authority Messages should first announce the author- ity giving the message, i.e. “This is the Colorado DOT” or “This is the Maryland State Police”. This gives credibility to the message that follows. Highway Technologies, Inc. 81 Texaco Road, Mechanicsburg, PA 17050 717 691-8007 CASE Height – 5” Width – 8” Depth – 3“ Weight – 5 lbs.

In doing so, the FCC also permits CB stations to operate without station identification. Elimination of individual station licenses results in no lessening of the operating privileges or responsibilities of CB users. An operator of a CB radio station is still required to comply with the Communications Act and with the rules of CB Radio Service. Rules You Should Know In common with all other CB operators, you must comply with the general rules prohibiting music, profanity, promotion of illegal activities, selling of merchandise or services, and blasting others off the air with illegally amplified transmitters. Although one-way communications are generally not allowed, operation of the Wizard for its intended purpose is permitted. Rule 18 (d) provides specific permission to establish one-way communications concerning highway conditions to assist travelers. Since Rule 7 (b) reserves Channel 9 for emergency communications or travelers assistance, channel 9 may be a good choice as channel B. Why a Wizard? 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. The Wizard is not intended for unattended operation. An operator should be in control of the system at all times. Elimination of Licensing Rules You Should Know Standard Menu Structure Although the Wizard is capable of many variations of set- tings, experience to date has shown that most operators use only channel 19 with a brief message.

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 = 3960 mW G* = Antenna Gain = 2.15 dBi = INVLOG(2.15/10) = 1.64 *Antenna Gain based on an ideal ½-wave dipole. Therefore: R = 45cm (Continuous operation) From this calculation, the minimum safe distance is 45 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 18 cm. R = 18 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 18cm from personnel. For this reason the minimum safe distance is met by the typical mounting of the antenna. )()( 25.0464.13960××÷×=πmWR
