Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. Warning ( Part 15.21 ) Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. RF Exposure ( OET Bulletin 65 ) To comply with FCC RF exposure requirements for mobile transmitting devices, this transmitter should only be used or installed at locations where there is at least 2m separation distance between the antenna and all persons. Preface EZCom-LP is an OEM radio module for professional installation in products or assemblies for resale. This device is not intended or marketed for installation by end users. Should EZCom-LP be used for fixed point-to-point operation as defined in FCC rule 15.247.(b).iii the equipment operator, or if the equipment is professionally installed, the installer, is responsible for ensuring the system is used exclusively for point-to-point operations. RF Exposure Information When used in a fixed configuration with the Yagi antenna or a mobile configuration with the omni-directional antenna the antenna should be located at least 2 meters from normal human proximity. Physical Installation The unit should be firmly attached at four mounting points. The holes are sized for #6 screws and are 5.7” apart on in the long dimension and 1.125” apart in the short dimension. It is critical that the mounting method not touch any of the components mounted on the PCB. Vibration mounts should be used if the device is expected to see shock or vibration in excess of 1G. The SMA connectors should be secured with 8 ounce-inches of torque. Ensure that the cabling does not present more than a few pounds of stress to the connectors themselves. With enough leverage, (such as seen with 0.5” and larger coax) it is possible to break the solder joints on the connectors. Electrical Issues The system supply must be 5V +/- 2%. As the main power amplifier runs directly off the 5V supply with only passive filtering it’s important to keep the voltage within these limits. Under voltage will cause the unit’s microprocessor to enter reset mode. Over voltage could potentially damage the transmit section. A power supply able to deliver at least 1 Ampere should be used. Place the supply close to the radio (less than 3 feet), use 22 gauge or larger wire and if possible provide a 470uF or larger capacitor between power and ground where it enters the radio. The capacitor isn’t needed if the supply can be shown not to droop out of voltage tolerance when the radio transmits. Antennas Use only the following antennas: Antenex YB8966 9.2 dBd yagi, must have at least 2.3 dB of cable loss (60 feet of LMR400, or equiv.) Maxrad MFB9157 7 dBd omni, must have at least 0.2 dB of cable loss (5 feet of LMR400, or equiv.) Antennas of the same type but with lower gain may be substituted if desired so long as the cable lengths are not changed from those tested. Antennas of higher gain are prohibited. Contact Grayhill if you feel you must use a higher gain antenna. Yagi Installation Figure 1. Recommended Antenex Yagi antenna configuration. The Yagi antenna should be mounted on a tower or pole with clear line of sight to the target radios. As a Yagi antenna concentrates it’s gain along the direction of the long axis care should be tak…

Product Description The EZCom is DSSS Radio Transceiver is an OEM for professional installation in products or assemblies for resale. This device is not intended or marketed for installation by end users. The EUT is a 902 to 928 MHz Direct Sequence Spread Spectrum Transceiver. 8. Test Requirements The above mentioned tests were performed in order to determine the compliance of the transceiver with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.207 15.247b 15.247e 15.205 15.247c 15.209 15.247a2 15.247d All radiated emissions tests were performed to measure the emissions in the frequency bands described by the above sections, and to determine whether said emissions are below the limits established by the above sections. These tests were performed in accordance with the procedure described in the American National Standard for methods of measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (ANSI C63.4-2001). Another document used as reference for the EMI receiver specification was the International Special Committee on Radio Interference CISPR 16-1 (2002).
