The CRU consists of the main CRU device, a Base End Assembly (BEA) and a Head End Assembly (HEA). These three discrete devices make up the CRU. The CRU is intended for use by properly trained seismic field personnel. Regulatory and Safety Guidelines Regulations regarding the use of the radio modems vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. Other countries, such as United States, require end-user licensing. Consult your local communications governing agency for licensing information. Before operating a CRU with a radio modem, determine if authorization or a license to operate the unit is required in your country. Obtaining an operator’s permit or license for the CRU for the location or country-of-use is the responsibility of the end user. NOTE: This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Input/Output, Inc. 4 CRU User Guide NOTE: In United States, for the 217 – 220 MHz band, the maximum antenna height above average terrain (HAAT) is 152 meters (500 feet). Improper installation could void the user’s authority to operate the equipment. Certification Certification, covers technical parameters of the equipment related to emissions that can cause interference. Certification is granted to the manufacturer or importer of the transmission equipment, independent from the operation or licensing of the units. Some countries have unique technical requirements for operation in certain radio modem frequency bands. Unauthorized modification to the units voids the Certification, the warranty and the operational license of the equipment. CAUTION: Changes or modifications to this equipment not expressly approved, in writing, by Input/Output could void the user’s authority to operate the equipment. Input/Output, Inc. 5 CRU User Guide Licensing Many countries require that the operator of a radio, or radio modem, obtain a license prior to operating the radio, or radio modem. Some do not. Consult your local communications governing agency for licensing information. Obtaining an operator’s permit or license for the Firefly CRU for the location or country-of-use is the responsibility of the end user. Before operating this radio modem, you are legally required to obtain frequency licenses as required by the country-of-use. Please contact your local communications governing agency for the licensing requirements for each of these radio modems. Safety Exposure to radio frequency (RF) energy is an important safety consideration. The FCC has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment as a result of its actions in General Docket 79- 144 on March 13, 1986. Proper use of this radio modem results in exposure below government limits. The following precautions are recommended: • A 20 cm separation should be maintained between the antenna and all persons during normal operation, per Part 1.1307 of the FCC Rules and Regulations. • All equipment must be properly grounded according to Input/Output installation instructions for safe operation. • All equipment should be serviced only by a qualified technician. FCC ID Label Figure 1 is an example of the FCC ID label for the CRU radio. Figure 2 shows where the label is located on the CRU radio. The size of the label is approximately 1.75 X 3.50 inches.

The Schematic Diagrams submitted seem not to include the RF Circuitry or the Head End Amplifier (HEA).? Please update the schematics to include the RF circuitry of the VHF transceiver boards and the HEA. ANS1 Schematics of VHF transceiver board and HEA attached. VHF transceiver is identical to the one used in previously granted product MCV-FSU101 2. The image resolution of the Block Diagram exhibit is not sufficient to read the text. Please provide a new Block Diagram exhibit that is legible. ANS2 HEA, BEA and CRU block diagrams attached 3. The MPE exhibit is unclear on several issues. The limit is stated as 0.2mW/cm2, but the calculation at 30.6 cm is 0.47mW/cm2. There is a row for a 2% duty cycle, but no explanation as to why this is used. The manual states that a 20cm separation is required, but does not provide any antenna selection guidance restricting the gain for either power or MPE limits. ANS3 MPE has been corrected. The correct gain for highest gain antenna is 8.2 dBi. The correct duty cycle is 20%. MPE distance is approximately 27 cm, user manual calls out 30 cm. Antenna data sheet, corrected MPE, and updated user manual are attached 4. The general test equipment list in the test report indicates that the reference antenna calibration was due on 8/8/06. Was this antenna out of calibration during the radiated testing? ANS4 Revised report is attached with typo corrected 5. The FCC ID number in the External and Internal photo exhibits does not contain the '-' that is contained in the FCC ID number in all other exhibits. Additionally, the application seems to be for the CRU with the Head End Amplifier, but the HEA does not seem to show up in the External or Internal photo exhibits. Please update the photo exhibits accordingly. ANS5 Additional photos and corrected photo exhibit will be attached to a separate email 6. Please provide the DC Voltages and Currents information required by FCC 2.1033. ANS 6 The the peak current of the amplifier in the BEA with +33DBm out of the amplifier is 3.0 Amps, the Voltage is 27.5 Volts The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 30 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the e-mail address listed below the name of the sender. Best regards, Chris Harvey [email protected]
