SONY. DIGITAL AUDIO RECORDER PCM-7030 MAINTENANCE MANUAL 1st Edition (Revised 7) Serial No. 20001 and Higher (UC) Serial No. 50001 and Higher (EK) WARNING For the customers in U.S.A. This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instructions manual. may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference in which case the user at his own expense will be required to take whatever measures may be required to correct the interference. Important- To insure that the complete system (including this peripheral) is capable of complying with the FCC requirements. it is recommended that the user make sure that the individual equipment of the complete system has a label with one of the following statements. "This equipment has been tested with a Class A Computing Device and has been found to comply with Part 15 of FCC rules." SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 3.5 mAo Leakage current can be measured by anyone of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufac- turers' instructions to use these instruments. 2. -or"This equipment complies with the requirements in Part 15 of FCC rules for a Class A Computing Device." -or equivalent. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a YOM or battery-operated AC voltmeter. The "limit" indication is 5.25 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive YOM that is suitable. Nearly all battery operated digital multimeters that have a 20 V AC range are suitable. (See Fig. A) 3. The shielded interface cable recommended in this manual must be used with this equipment in order to comply with the limits for a computing device pursuant to Subpart J of Part 1 5 of FCC Rules. For the customers in Canada This apparatus complies with the Class A limits for radio noise emissions set out in Radio Interference Regulations. To Exposed Metal Pans on Set Pour les utilisateurs au Canada Cet appareil est conforme aux normes Classe A pour bruits radioelectriques. specifies dan
