When mounting the Universal Transceiver, machinery, walls, doors and other physical structures should be avoided in order to achieve maximum antenna performance. ASSEMBLY PROCEDURE – Universal Transceiver 1. Locate a clear wall, ceiling or non-metal rack area to mount the Universal Transceiver. The unit should be mounted at least one foot (1') from metal pipes or racks. Avoid mounting Universal Transceiver near any sources of potential noise interference such as electric motors, fluorescent lamps, radio transmitters, infrared devices, etc. (at least ten feet (10') of clear area is recommended). Line of site Operating Instructions 2 31082A obstructions may interfere with maximum signal strength and reception. 2. Using the Universal Transceiver mounting bracket as a guide, mark two spots to be drilled to support the unit. Use extreme caution to avoid drilling into walls containing wiring or pipes. ASSEMBLY PROCEDURE – Base Station PC 1. Determine a suitable wall or rack location to mount the Base Station PC within twenty-five feet (25') of the Universal Transceiver unit near a standard 110 VAC power supply and approved telephone jack. Use only the supplied hardware brackets when mounting the Base Station PC. Do not drill or tap any holes in the case of the Base Station PC. 2. Attach the RS232 nine-pin cable to the Universal Transceiver. Carefully route this cable to the Base Station PC and attach cable to RS232 receptacle. 3. Secure the RS232 Cable to wall and rack areas using approved cable ties and wall style cable fasteners. Do not allow anything to rest on the Base Station PC or its cables including other signal transmission cables or lines. 4. Attach an approved telecommunications cable to the receptacle port on the rear of the Base Station PC. Neatly secure the cable along its path using approved cable ties. 5. Attach the 110 VAC power cable to the rear of the Base Station PC. Plug the power cable in to the nearest 110 VAC power source. 6. Turn Base Station PC power on using the rocker switch located on the rear of the unit. There are no user serviceable parts in the Universal Transceiver or Base Station PC.

UNIVERSAL TRANSEIVER Professional Testing (EMI), Inc. FCC ID: OBH 22220 Page 2 of 2 The Universal Transceiver Module operates under Part 15and is classified as a “Mobile Device” by the guidance given in 47 CFR 2.1091 and OET Bulletin 65, which states: “Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer and transportable cellular telephones (“bag” phones), are considered to be mobile devices if they meet the 20 centimeter separation requirement.” The Universal Transceiver Module meets this description including the requirement that it be used more than 20 centimeters from the user. “...are subject to routine environmental evaluation for RF exposure use if they operate at frequencies of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 watts or more,...” The Universal Transceiver Module has a typical output power of 0 dBm or 1 mW. The peak, measured power in the fundamental was 90.0 dB (uV/m). Using the formula: P = .3 V 2 The measured power is 0.30 mW in the fundamental. An earlier reading of the fundamental, made without a preamplifier measured a result of 92.9 dB (uV/m), which yields a result of 0.59 mW. This measurement is considered less accurate than the value reported in the test report. However, it is reported here as it give a worst case measurement for this purpose. However, both measurements are clearly well below the requirement. Therefore, a routine environmental evaluation for RF exposure is not required.

The Universal Transceiver Module is used together with one or more Data Collection Modules and Temperature Sensor Units for gathering battery performance and vehicle utilization data. The EUT operates in the 902 - 928 MHz band and is designed for compliance with 47 CFR 15.249 of the FCC rules. The Universal Transceiver Module/Base Station consists of a DC to DC converter power supply, microprocessor and RF transceiver constructed entirely of surface mount components attached to a 2.4" X 2.4" PC board, mounted in a metal enclosure with an external, permanently attached antenna. The serial port of the small personal computer to which it is attached powers it. The device employs a bi-directional RF data link to gather data from Data Collection Modules attached to batteries. The device operates at a frequency of 916.5 MHz and employs on-off keying as the modulation method. Data is Manchester encoded and transmitted at an approximate rate of 12Khz. The device operates autonomously and is normally in the receive mode. Periodically, it may transmit a 200-millisecond burst of data to convey status information to Data Collection Modules or to request specific data from them. The Personal computer is a model ILH386V with a 386 processor operating at 25 MHz. The PC contains an internal hard disk drive, a floppy disk drive, a flash disk drive. Specific test requirements for this device include the following: 47 CFR 15.249 Fundamental Transmit Power 47 CFR 15.249 Spurious Radiated Power & 15.205 47 CFR 15.249 Occupied Bandwidth 15.231 & 2.989 (2.989 used as Procedural Reference) 47 CFR 15.203 Antenna Requirement 47 CFR 15.207 Conducted Emissions The system tested consisted of the following: Manufacturer & Model FCC ID # Description Lester Electrical, Inc.
